AB  - Phytate, as an important mineral storage compound in seeds, is vital for seed/grain development; it is often considered to be an antinutritional substance. The objective of this study was to develop a rapid and inexpensive colorimetric method of measuring phytate and inorganic P (Pi) concentrations from maize, soybean and sunflower seed/grain extracts, by combining adequate precision and simplicity, ideal for breeders interested in improving simultaneously Pi and phytate levels. The investigated extraction mediums: double distilled (DD) H2O, 2.4 % HCl and 5 % trichloracetic acid (TCA) were proved to be suitable for the analysis of phytic acid and inorganic phosphorus in seed extracts. The advantages of 5 % TCA over to DD H2O and 2.4 % HCl were reflected through the low limit of detection for both phytic acid and Pi and good recovery with low bias. A low detection limit for Pi is important for samples with naturally low Pi concentrations, such as soybean seeds.
AB  - Fitat je važan za razvoj semena i služi za skladištenje minerala. On se uglavnom smatra za antinutritivnu supstancu. Cilj istraživanja je bio da se razvije brza i jeftina kolorimetrijska metoda za merenje koncentracije fitata i neorganskog fosfora (Pi) iz ekstrakta semena kukuruza, soje i suncokreta, kombinujući određenu preciznost i jednostavnost, idealne za selekcionere zainte- resovane za istovremeno poboljšanje odnosa Pi i fitata u semenu. Ispitivana ekstrakciona sredstva: bidestilovana voda (DD H2O), 2,4 % HCl i 5 % trihlorsirćetna kiselina (TCA) su se pokazale pogodnim za analizu fitinske kiseline i Pi iz ekstrakta semena. Prednost 5 % TCA u odnosu na DD H2O i 2,4 % HCl se ogleda u niskoj granici detekcije za fitinsku kiselinu i Pi, dobrom recoveryju i niskim vrednostima odstupanja (bias). Niska granica detekcije za Pi je važna za uzorke sa prirodno niskom Pi koncentracijom, kao što je seme soje.

AB  - Irrigation, as a major solution to drought, is connected with irreversible nitrogen losses due to leaching. Improvement of soil management through the application of biodegradable polymers, as soil water bearers, gives a new approach in drought control. Trials were performed to examine the influence of Super-Hydro-Grow polymer (SHG), a starch-based polymer, on maize growth and grain yield, compared with rain-fed and irrigation cropping practices. The climatic conditions during 2006 were moderate compared to the ones in 2007, which was a relatively dry year. The positive impact of the polymer on plant growth was observed through the significant increases in the fresh matter of the shoots and grain yield, compared to the other treatments. In addition to maintaining soil moisture (as its main function) during the vegetative period, the polymer suppressed soil N deprivation making it advantageous cropping practice. Furthermore, the extended effect of the SHG polymer on the subsequent rotational crops should be considered.

AB  - The difference in the growth of maize seedlings originating from seeds injured by accelerated ageing, as well as those altered by restoring with low 2,4-D (2,4-dichlorophenoxyacetic acid) concentrations was examined, from the point of view of free energy and redox potential. The ageing decreased germination ability, the seedling growth and free energy, with no remarkable influence on the redox capacity. Meanwhile, the 2,4-D treatment increased the germination percentage and the seedling growth, by better energy utilisation, with shifting of the redox balance to a reducing environment. From this point of view, the free energy and the redox potential are useful tools for the determination of biological vitality.

Starenje je smanjilo sposobnost klijanja semena, rast klijanaca i njihovu slobodnu energiju, bez znatnog uticaja na redoks potencijal. Sa druge strane, 2,4-D je uticao na bolje iskorišćenje energije i pomeranje redoks ravnoteže ka redukovanoj sredini, povećavajući klijavost i rast klijanca.

AB  - High weed infestation of seed crops often makes various measures that should be performed at the optimum time difficult, hence post-emergence herbicides have become the usual way of weed control in maize seed crops. The introduction of sulfonylurea herbicides has resulted in a higher susceptibility in maize inbreds. The aim of this study was to examine the effects of six post-emergence herbicides, including sulfonylurea herbicides, on the contents of fresh matter, soluble proteins, free thiolic groups and total phenolics in one-month-old plants, as well as on the grain yield of 15 commercial ZP maize inbred lines. The obtained results show that inbred plants have a whole range of responses to herbicide application. The changes in content of phenolics did not vary over a broad range among the applied herbicides; they followed mainly the level observed in control plants. However, greater variations between the results were obtained for the content of free thiolics, which are defenders against oxidative attack. The overall influence of herbicides could be considered as a decrease in the content of thiolics. Most of the applied herbicides expressed temporary stress, evidenced by a decrease in the fresh matter of the shoots, without affecting of yield at the end of vegetation. This could be connected to recovery mechanisms that include the activity of antioxidants, primarily of thiolics.

AB  - Two maize hybrids with a different ability to maintain seed germination were examined during the course of accelerated aging (AA). Initially, the similar seed reduction potential of the GSSG/2GSH half-cell increased in H1 (dent hybrid) without influencing the seed germination ability up to the 6th day of AA, while in H2 (sweet corn hybrid), it was not changed up to the 6th day of AA but with a significant later loss of seed germination ability. During the AA course, the amount of free thiol decreased in H1 and increased in H2. Irrespective of the continual increase of the differential Gibbs energy during AA, the characteristics of the examined hybrids are possibly connected to the different metabolic pathways of the seeds: H1 is characterized by higher entropy and positive enthalpy values, while H2 had negative entropy values and a decreasing trend of enthalpy, indicating a shift of the system from a relatively ordered to a disordered state. The different types of nanomolecular switches, resulting in a faster decrease of GSH in the H2 than in the H1 hybrids, indicate that a combination of the GSSG/2GSH half-cell potential and thermodynamics could be a useful tool to quantify plant stress.

Količina PSH se smanjivala kod H1, dok je rasla kod H2 tokom tretmana starenja. Bez obzira na kontinuiran pad slobodne energije tokom ubrzanog starenja, osobine semena ispitivanih hibrida su možda bile vezane za drugačije metaboličke puteve: H1 karakteriše visoka entropija i pozitivne vrednosti entalpije, dok je za H2 karakteristična relativno niska entropija, uz negativne vrednosti entalpije, ukazujući na pomeranje sistema iz relativno uređenog u neuređeno stanje. Drugačiji tipovi nanomolekulskih prekidača, utičući na brži pad GSH kod H2 u odnosu na H1, ističu da se kombinacija GSSG/2GSH ćelijskog potencijala i termodinamike mogu koristiti pri kvantifikaciji biljnog stresa.

AB  - The specific sowing structure of maize seed crops requires special attention to weed management. The maize inbred lines are susceptible to a range of stress factors, so as the herbicide application could introduce temporary or permanent stress, dependently on genotype susceptibility and agro-meteorological conditions. The aim of experiment was to investigate the influence of post-emergence herbicides on content of the phytic and inorganic phosphorus 48 hours after herbicide application (4-6 leaves phase) and then 21 days after application, as well as on the grain yield of 10 ZP maize inbreds. The difference in phytic P content after 21 days was followed by yield alterations in the majority of inbreds. Decrease of the phytic P influenced by herbicides, in relation to control, 48 hours and particularly 21 days after application, could be tied to phytate positive impact to stress tolerance, owing to its antioxidative activity; so as, at the most of inbreds was observed permanent stress, with no significant influence on grain yield. Meanwhile, during the period of 21 days after herbicide application, the inorganic P content correlated with phytic P content, without significant alterations of grain yield.
AB  - U semenskim usevima kukuruza, zbog specifične strukture setve se posebna pažnja obraća na kontrolu korova. Samooplodne linije kukruza su inače osetljive prema brojnim stresnim faktorima. Primena herbicida može dovesti do pojave privremenog ili permanentnog stresa, zavisno od osetljivosti genotipa i agro-meteoroloških uslova. Cilj eksperimenta je bio da se ispita uticaj herbicida koji se primenjuju nakon nicanja kukuruza, na sadržaj fitinskog i neorganskog fosfora 48 sati nakon aplikacije herbicida (u fazi 4-6 listova), a potom nakon 21 dana, kao i na prinos zrna 10 komercijalnih ZP linija kukuruza. Razliku u sadržaju fitinskog P nakon 21 dana od tretiranja pratila je promena prinosa kod većine linija. Takođe, smanjenje sadržaja fitinskog P pod uticajem herbicida u odnosu na kontrolu, 48 sati nakon tretiranja, a posebno nakon 21 dana bi moglo biti vezano za pozitivnu ulogu fitata u toleratnosti na stres, zahvaljujući njegovoj antioksidativnoj aktivnosti, tako da je kod većine tretiranih linija bio zabeležen privremeni stres, bez značajnijeg uticaja na prinos. Sa druge strane, sadržaj neorganskog fosfora u periodu do 21 dana od momenta tretiranja herbicidima u većem stepenu je bio u korelaciji sa sadržajem fitinskog fosfora, ne utičući značajnije na formiranje prinosa.

AB  - The phytate function in plants is still not completely understood: it is the primary storage P form in seeds that is utilized during germination and early seedling development. Approaches to resolve problem of the bad nutritive quality of grain phytate include engineering of crops with reduced levels of seed phytic acid. The objective of this study was to investigate genetic variability and correlation of phytic (Pphy) and inorganic phosphorus (Pi) and soluble proteins among 28 maize populations, consisted into three groups: low-, intermediate- and high-phytic populations, with the aim to determine the potential of enhancing the P profile of maize plants and high grain yield through selection. The highest genetic variability of Pi and Pphy content in leaves was expressed in group with intermediate Pphy content in grain. Meanwhile, leaves of low-phytic populations were characterized with low Pphy, too (averagely 18%) and high content of soluble proteins (averagely 15%) in relation to high- and intermediate-phytic populations. Additionally, the lowest genetic variability of protein content was also noticeable in leaves of low-phytic populations. Positive correlation between Pi and protein content was observed in leaves of low- and high-phytic populations. The negative correlation between Pphy and Pi was detected in maize grain, but correlation was significant only in intermediate-phytic group. The highest, but not significant, average yield was observed in group of low-phytic populations, as well as its relative high genetic variability. That indicates that development of high yielding genotypes with lower phytate in grain is reasonable, and could be potentially useful in enhancing the sustainability and decreasing of environmental impact in agricultural production.

Najveća genetska varijabilnost Pi i Pphy je bila ispoljena u listovima kukuruza populacija sa srednjim nivoom fitata u zrnu. Međutim, nisko fitinske populacije su pored niskog sadržaja Pphy u listovima (prosečno za 18%) imale i viši nivo rastvorljivih proteina (prosečno za 15%), u odnosu na visoko i srednje fitinske populacije. Takođe, najniža genetska varijabilnost u sadržaju proteina je bila prisutna u listovima nisko fitinskih populacija.

Najveći prosecan prinos, ali ne značajno, je bio prisutan kod nisko fitinskih populacija, uz najveću genetsku varijabilnost. Ovo ukazuje na mogućnost razvijanja visokoprinosnih genotipova sa niskim nivoom fitata u zrnu, što bi moglo biti potencijalno korisno sa aspekta održivosti i smanjenja uticaja okoline na poljoprivrednu proizvodnju.

AB  - Analysis of 60 maize populations was conducted to identify genotypes that had either low or high concentration of phytate. Genetic variability in seed phytate content was observed, with values ranging from 1,147 to 4, 13 g kg-1. Inorganic phosphorus (Pi) concentrations were between 0, 35 and 1, 29 and averaged 0, 65 g kg-1. Three groups of populations were identified as having low, intermediate and high phytate content. The low phytate concentration was measured in eight, intermediate in 25 and high in 27 populations. Positive correlation was found between phytate and protein. Population 216 had the lowest phytate concentration of 1, 14 gkg-1, and a Pi concentration 40% greater than Pi mean but lower than average protein content. This population will be used for further breeding genotypes with low phytate content and good agronomic traits.

AB  - In recent years breeding programmes with the aim of deriving soya bean genotypes with a reduced phytate content and an increased concentration of inorganic phosphorus in grain have been developed all over the world. The objective of the present study was to determine the genetic variability of the contents of phosphorus, phytate and inorganic phosphorus in seeds of soya bean genotypes and according to obtain results to select genotypes for the further selection programmes for the reduced phytate content. Thirteen genotypes were observed and the phytate content in them varied from 3.35 g kg-1 to 4.43 g kg-1 (4.02 g kg-1 on the average). The concentration of inorganic phosphorus significantly differed over observed genotypes and ranged from 0.16 g kg-1 to 0.516 g kg-1. The cultivar Lana, with the reduced trypsin inhibitor content, has a low phytate content and a high inorganic phosphorus content. The genotype L1701 with naturally low phytate content shall be included into selection programmes for the reduced phytate content in soya bean seeds.
AB  - Poslednjih godina u svetu su razvijeni selekcioni programi sa ciljem stvaranja genotipova soje sa smanjenim sadržajem fitina uz povećanje koncentracije neorganskog fosfora u semenu. Cilj našeg rada je utvrđivanje genetičke varijabilnosti sadržaja fosfora, fitina i neorganskog fosfora u semenu genotipova soje i na osnovu dobijenih rezultata izbor genotipova za buduće programe selekcije na smanjeni sadržaj fitina. Ispitano je trinaest genotipova i utvrđeno je da se sadržaj fitina kretao od 3,35 g kg-1 do 4,43 g kg-1, prosečno 4,02 g kg-1. Koncetrancija neorganskog fosfora se značajno razlikovala između ispitivanih genotipova i bila je u opsegu od 0,16 g kg-1do 0,516 g kg-1. Sorta Lana, sa smanjenim sadržajem tripsin inhibitora, ima nizak sadržaj fitina i visok sadržaj neorganskog fosfora. Genotip L1701, sa prirodno niskim sadržajem fitina, biće uključen u selekcione programe za smanjeni sadržaj fitina u semenu soje.

abstract = "In recent years breeding programmes with the aim of deriving soya bean genotypes with a reduced phytate content and an increased concentration of inorganic phosphorus in grain have been developed all over the world. The objective of the present study was to determine the genetic variability of the contents of phosphorus, phytate and inorganic phosphorus in seeds of soya bean genotypes and according to obtain results to select genotypes for the further selection programmes for the reduced phytate content. Thirteen genotypes were observed and the phytate content in them varied from 3.35 g kg-1 to 4.43 g kg-1 (4.02 g kg-1 on the average). The concentration of inorganic phosphorus significantly differed over observed genotypes and ranged from 0.16 g kg-1 to 0.516 g kg-1. The cultivar Lana, with the reduced trypsin inhibitor content, has a low phytate content and a high inorganic phosphorus content. The genotype L1701 with naturally low phytate content shall be included into selection programmes for the reduced phytate content in soya bean seeds., Poslednjih godina u svetu su razvijeni selekcioni programi sa ciljem stvaranja genotipova soje sa smanjenim sadržajem fitina uz povećanje koncentracije neorganskog fosfora u semenu. Cilj našeg rada je utvrđivanje genetičke varijabilnosti sadržaja fosfora, fitina i neorganskog fosfora u semenu genotipova soje i na osnovu dobijenih rezultata izbor genotipova za buduće programe selekcije na smanjeni sadržaj fitina. Ispitano je trinaest genotipova i utvrđeno je da se sadržaj fitina kretao od 3,35 g kg-1 do 4,43 g kg-1, prosečno 4,02 g kg-1. Koncetrancija neorganskog fosfora se značajno razlikovala između ispitivanih genotipova i bila je u opsegu od 0,16 g kg-1do 0,516 g kg-1. Sorta Lana, sa smanjenim sadržajem tripsin inhibitora, ima nizak sadržaj fitina i visok sadržaj neorganskog fosfora. Genotip L1701, sa prirodno niskim sadržajem fitina, biće uključen u selekcione programe za smanjeni sadržaj fitina u semenu soje.",

AB  - The modification was done with a purpose to find the integral medium for extraction of some organic and nonorganic substances responsible for seed germination and plant growth: phytine, PO4 ion, as well as, stress protecting substances of a different origin: total soluble phenols and thiols in seeds and leaves. This modification implied the selection of the extraction medium suitable for the quantitative isolation of substances from the common extracts of the initial material (seed, leaf). It was shown that highly diluted 0.15% tri-sodium-citrate can be used as a universal extraction medium for phytine, ortho-phosphate ion, soluble total thiols and total phenols. This medium allowed the efficient extraction of phytine and phosphate from degermed milled maize seeds. Also, it is sensitive enough to make difference between their content in young and mature maize leaves. Two weighted samples of 0.1-0.5 g, from the average sample of 25 seeds or seedlings, five young plants, as well as, two leaves (above and bellow maize cob) from three plants in the tasseling stage, with the addition of 8-15 ml of the above mentioned solution, provided a spectrophotometrical determination of these substances in 2-3 replicates. The procedure was developed to be suitable for the introduction and breeding, including a unique minimum average sample for all observed parameters. The application of precise and rapid spectrophotometrical methods, modified for large sample series, provides the reduction in the number of replicates to two (the statistical minimum), hence there is enough space for the introduction of the other desirable analyses.

AB  - A dynamics of seed mass defect and a previous process of the water input during germination was determined by a trial with five soybean cultivars and four sunflower hybrids, following the ISTA Rules. It was noticed that leaching, which led to the mass defect (smDef), was permanent during 8 and 10 days of soybean and sunflower germination, respectively. The two confronted processes, the liquid input and the solid output, could be operable at the level of a thermodynamic parameter of Gibbs free energy (G), i.e. net supplemental free energy (netGspl). Hence, this type of free energy - net supplement, differentiates in two examined plant species (between the first and the last day of germination): soybean in a range from -53.23 to -69.82 J mol-1 seedling-1 and sunflower from -46.35 to -91.94 J mol-1 seedling-1. Furthermore, the daily change of net supplemental energy underlined the three points ingenotypes of both species: after the first, before the last day of germination and in the maximum (-67.50 and -75.25 J mol-1 seedling-1 in soybean, then, -94.97 and -103.79 J mol-1 seedling-1 in sunflower) between the 4th and the 7th day of germination depending on a genotype.

AB  - The 2,4-D was applied as hormetic, to increase germination ability and growth of seedlings originated from 19 maize inbred lines seeds (germination between 2 and 97%). The seeds were soaked in solution of 2,4-D, diluted to hormetic concentration. After germination capacity was determined, normal seedlings were fractionated into: root, shoot and seed rest, in order to establish fresh and dry weights and volume of free water in them. Sum of hydrolysis, biosynthesis and free energy were calculated. Increased germination percentage, by 2,4-D was not linear for all germination values, meaning that germination was more than doubled in seeds with initial germination below 10%. On the other hand, germination increase was only 2% in seeds with initial germination over 90%. Additionally, fresh weight of root and shoot increased up to 90 and 49%, respectively as consequence of promoted hydrolysis and biosynthesis. The high values of free energy (> +7 KJ) in control seedlings indicated that potential energy was spent, thus lowering growth and biosynthesis levels. The 2,4-D treated seedlings, with potential energy about +/- 0.1 KJ point out that processes in seedling are spontaneous, i.e. are oscillating about equilibrium, enabling more efficient utilization of seed substance, affirmed by elevated biosynthesis and growth.

AB  - The five maize inbred lines were subjected to concomitant treatments of herbicides: EPTC, alachlor and S-metolachlor and extended low temperature (22°C during 6 days and 10°C during 15 days). The fresh and dry substance and water content were determined. The calculated parameters fluctuated: concentration between 72 and 219 g L- 1; then, pseudo-specific density between 47 and 51 µmol mg -1. The free energy, spend for 1 mg of dry substance biosynthesis was higher in low temperature conditions and in alachlor treatment at both temperature conditions. Meanwhile, the changes of differential free energy, enthalpy and entropy, as thermodynamical parameters, followed the changes of fresh, dry substance and water volume in root and shoot of examined inbreeds, therefore the inbreeds with lower values of differential free energy, enthalpy and entropy had the higher tolerance to herbicide treatments.
AB  - Pet samooplodnih linija kukuruza bilo je izloženo kombiniovanom tretmanu herbicida: EPTC, alachlora i S-metolachlora u kombinaciji sa produženom niskom temperaturom (22°C tokom 6 dana i 10°C tokom 15 dana). Određivan je sadržaj sveže i suve supstence i sadržaj vode. Obračunski parametari su varirali: između 72 i 219 g L-1, zatim, pseudo-specific density između 47 I 51 µmol mg -1. Slobodna energija, utrošena za biosintezu 1 mg suve supstance imala je niže vrednosti pri nižoj temperature i u tretmanu sa alahlorom, u oba temperaturna režima. Takođe, promene diferencijalne slobodne energije, entalpije i entropije, kao termodinamičkih parametara, pratile su promene sveže i suve supstance i sadržaj vode u korenu i izdanku svih ispitivanih linija. Sa druge strane, linije koje su imale niže vrednosti diferencijalne slobodne energije, entalpije i entropije, imale su i veću tolerantnost prema upotrebljenim herbicidima.

The free energy, spend for 1 mg of dry substance biosynthesis was higher in low temperature conditions and in alachlor treatment at both temperature conditions. Meanwhile, the changes of differential free energy, enthalpy and entropy, as thermodynamical parameters, followed the changes of fresh, dry substance and water volume in root and shoot of examined inbreeds, therefore the inbreeds with lower values of differential free energy, enthalpy and entropy had the higher tolerance to herbicide treatments., Pet samooplodnih linija kukuruza bilo je izloženo kombiniovanom tretmanu herbicida: EPTC, alachlora i S-metolachlora u kombinaciji sa produženom niskom temperaturom (22°C tokom 6 dana i 10°C tokom 15 dana). Određivan je sadržaj sveže i suve supstence i sadržaj vode. Obračunski parametari su varirali: između 72 i 219 g L-1, zatim, pseudo-specific density između 47 I 51 µmol mg -1. Slobodna energija, utrošena za biosintezu 1 mg suve supstance imala je niže vrednosti pri nižoj temperature i u tretmanu sa alahlorom, u oba temperaturna režima. Takođe, promene diferencijalne slobodne energije, entalpije i entropije, kao termodinamičkih parametara, pratile su promene sveže i suve supstance i sadržaj vode u korenu i izdanku svih ispitivanih linija. Sa druge strane, linije koje su imale niže vrednosti diferencijalne slobodne energije, entalpije i entropije, imale su i veću tolerantnost prema upotrebljenim herbicidima.",

AB  - The two herbicides and their combined treatment influenced the change of water input in each of 15 investigated maize inbreds. The water volume (ml) fluctuated between 11 to 110% in shoot and 23 to 275% in root, what introduced the change of free energy (G) from -254.6 to -151.6 KJ in shoot and from -248.0 to -172.3 KJ in root. The difference in free, potential energy between non- and treatment (oΔtreatG) was in shoot from 11.1 to 90.2 KJ and in root from 16.8 to 75.7 KJ. Further, the lower magnitude of oΔtreatG amplitude between root and shoot implicated the tolerance of genotypes to applied herbicides. The energy, spent in biosynthesis of 1mg dry substance was amounted from 75.6 to 16.8 KJ mg-1; the applied herbicide treatments assembled the group of genotypes with lowered necessity of this energy, what has the positive implications in the sense of thermodynamics.

AB  - From 15 maize inbreds, submitted to alachlor and atrazine treatment in controlled conditions, after 14 days growing in sand under distilled water, fresh and dry weight and length of root and shoot were determined. The parameters derived of those measurements: concentration (gL-1), root: shoot relation and pseudospecific density (d, d-1, µmol mg-1) classified the mechanisms of herbicide influence in whole plants and roots or shoots. Thus, alachlor lowered weights, lengths, root: shoot relation and elevated concentration in all inbreeds, underlining the suppression of water input and root as the target. The atrazine, on the contrary, downed concentration, promoting the water-induced growth. The applications of diluted or combined herbicides’ forms segregated the genotypes to tolerant or sensitive as whole plant or partially root or shoot, only. The pseudo-specific density separated the genotypes to non- or stable system to hold up the induced change.

Bila su izvršena merenja sveže i suve mase, dužine korena i izdanka. Dobijeni parametri su poslužili za izračunavanje: koncentracije (gL-1), koren: izdanak relacije i pseudospecifične gustine (d, d-1, µmol mg-1).

Potrebno je naglasiti i smanjenu apsorpciju vode u koren, kao mesto sa najintenzivnijom reakcijom na alahlor. Sa druge strane, atrazin je smanjio koncentraciju, vodeći tzv. vodom indukovanom porastu.

AB  - A trial with four maize inbred lines with the ability to have different durations of seed germination in the course of the accelerated ageing (AA) treatment was set up. Changes of the content of total, reduced and oxidized glutathione (expressed as monomers) were observed in the seeds and seedlings before and after the treatment. For the first time, changes of glutathione in whole seedlings, as well as in the rest of the seed, were analyzed. It was noticed that maize in breds with a smaller decrease of the total glutathione but with an increase of the oxidized form had the ability of prolonged germination. In the control seed- lings, the amount of total glutathione was lower than in the treated ones. Maize seeds which lost germination faster had greater losses of total glutathione with an increased content of the oxidized form in seedlings. The ability of prolonged germination together with the possibility of glutathione synthesis in seedlings are genotypic traits.

AB  - A trial with four maize inbred lines with the ability to have different durations of seed germination in the course of the accelerated ageing (AA) treatment was set up. Changes of the content of total, reduced and oxidized glutathione (expressed as monomers) were observed in the seeds and seedlings before and after the treatment. For the first time, changes of glutathione in whole seedlings, as well as in die rest of the seed, were analysed. It was noticed that maize inbreds with a smaller decrease of the total glutathione but with an increase of the oxidized form had die ability of prolonged germination. In the control seedlings, the amount of total glutathione was lower than in the treated ones. Maize seeds which lost germination faster had greater losses of total glutathione with an increased content of the oxidized form in seedlings. The ability of prolonged germination together with the possibility of glutathione synthesis in seedlings are genotypic traits.

AB  - The ageing processes of living organisms, including seeds, relate, to a great extent, to the activity of free radicals. The aim of this study was to investigate changes of the most important antioxidative substances carotenoids, phenolic and thiolic compounds and reduced glutathione (GSH) in seeds of six maize genotypes with different ability to maintain germination. The germination decrease in all maize genotypes was followed by the decrease of all observed antioxidants. The greatest decrease was observed in GSH and thiols, while change of phenolic compounds was sigmoidal. The analysis of the share of certain observed antioxidants in the antioxidative capacity shows that maintenance of germination of all maize genotypes depended on changes of the GSH content.
AB  - Proces starenja svih živih organizama, pa i semena u velikoj meri je vezan za slobodnoradikalsku aktivnost. Cilj rada bio je da se ispitaju promene najznačajnijih antioksidativnih materija: karotinoida, fenolnih i tiolnih jedinjenja i redukovanog glutationa (GSH) u semenu šest genotipova kukuruza sa različitim očuvanjem klijavosti. Pad klijavosti semena prati i pad sadržaja svih ispitivanih antioksidanata, uz najizraženiji pad GSH i tiolnih jedinjenja i sigmoidalnu promenu fenolnih jedinjenja. Analizom pojedinačnog udela ispitanih antioksidanata u antioksidativnom kapacitetu zaključili smo da održanje klijavosti svih genotipova kukuruza u najvećoj meri zavisi od promena sadržaja GSH.

AB  - Selenium as a good free radicals trapper was incorporated in lettuce which is important in dietetical nurishent, in doses of 0, 1, 5 and 10 mg G! Se, together With Hoaglands solution in sand culture. The dose of 1mg 1 Se was separated for a practical use because it didn't affect yield. The dietetical quality was highered with decrease of antinutrients content and with increase of selenium content.
AB  - Salata je povrtarska vrsta vrlo cenjena u dijetetskoj ishrani. Stoga je postavljen ogled koji ima za cilj ispitivanje uticaja različitih doza selena (0, 1, 5 i 10 mg t1 Se) na nivo nutritivnih i antinutritivnih materija kod salate gajene kao peščane kulture. Selen je smanjio prinos salate, a povećao je sadržaj suve materije listova. Pri visokim dozama Se je smanjio sadržaj N, P, K, Ca i Mg, a povećao je sadržaj S i Se, što znači da salata lako usvaja Se. Takođe, Seje. od ostalih nutritivnih materija smanjio učešće glutationa, slobodnih tiolnih aminokiselina, fenolnih jedinjenja i vitamina C, povećao je sadržaj β - karotina i nije uticao na promenu nivoa hlorofila. Seje uticao i na promene antinutritivnih materija: povećao je nivo nitrata i celuloze, a smanjio je nivo nitrita i fitina, tako da su visoke doze Se delovale negativno na kvalitet salate. Doza od 1 mg 1 Se nije negativno uticala na nivo hranljivih materija, uz veći ni­vo Se, tako daje povećala nutritivni kvalitet salate.

AB  - Lettuce, a vegetable crop, is very recommendable in diets, but it is also susceptible to saline media. The trial with lettuce, as a sand culture, was set up during spring and autumn. The control variant was watered with modified Hogland solution, while the variant in which effects of salinity were observed was watered by mineral water St. George from Torda with extremely high degree of salinity. Saline mineral water did not affect changes of lettuce yield, nor content of phosphorus, potassium, sodium, vitamin C, P-carotene and chlorophyll, but it led to the decrease of nitrogen content (especially of nitrite form) and the increase of magnesium, sulphur and chlorine. Nevertheless, the nutritive value of lettuce was not reduced.
AB  - Salata je povrtarska vrsta koja je vrlo cenjena u dijetetskoj ishrani, a osetljiva je na zaslanjenje podloge. Salata je gajena tokom proleća i jeseni kao peščana kultura. Za razliku od kontrolne salate koja je zalivana sa modifikovanim Hoagland-ovim rastvorom, salata kod koje je ispitivan uticaj zaslanjenja zalivana je sa mineralnom vodom Sveti Đorde iz Torde, sa izrazito visokim stepenom zaslanjenja. Zaslanjena mineralna voda nije uticala na promenu prinosa salate, kao i sadržaja fosfora, kalijuma, natrijuma, vitamina C, hlorofda i B-karotina, ali je dovela do smanjenja sadržaja azota (posebno nitratnog oblika) i povećanja sadržaja magnezijuma, sumpora i hlora, što ne umanjuje njenu nutritivnu vrednost.
