AB  - The mode of action of agrochemicals on plants implies the totality of their effect on plant metabolism, growth and development. The effects of different doses of 24-epibrassinolide (24-EBL) as a class of brassinosteroid phytohormones on growth and other physiological processes in maize plants during different development stages are reviewed in order to assess the influence of these agrochemicals on various factors determining the yield of maize as an important agricultural crop. In addition, several examples are given of the effects of these phytohormones on other crops, fruits and vegetables, in terms of their effect on yield, yield quality, and increase in crop resistance to some types of stress. Own results are discussed in the context of other literature data.

AB  - Način delovanja agrohemikalija na biljke podrazumeva ukupan uticaj na metabolizam, rast i razvoj biljaka. U tom smislu u ovom radu je prikazan efekat 24-epibrasinolida (24-EBL), kao klase fitohormona brasinosteroida, na rast i druge fiziološke procese u biljkama kukuruza u različitim dozama i u različitim razvojnim fazama, kako bi se procenio uticaj na razne faktore koji određuju prinos ovog važnog poljoprivrednog useva.

AB  - The phenomenon of a midday decrease in quantum and all other efficiencies of photosynthesis has been acknowledged. Quantum efficiency of PSII in nettle is known to be lower at midday than in the morning or evening. On other hand, the parameters of induction of Chla fluorescence in stinging nettle (Urtica dioica L.) during the daytime were shown to depend on temperature alone. An increase in temperature also slowed down processes in reaction centres (RCs) and on the acceptor side of PSII, which showed its effect on electron transport in PSII and overall photosynthesis. A similar situation was found for red currant (Ribes spp.). The temperature effect was considered to be transient thermal inhibition of photosynthesis caused by diurnal changes in temperature.
AB  - Razmatran je fenomen podnevne inhibicije kvantne efikasnosti i drugih aspekata fotosinteze. Parametri kvantne efikasnosti PSII kod koprive su niži u podne nego ujutro ili uveče. Nađeno je, u oglednim uslovima, da parametri indukcije fluorescencije Chla kod koprive (Urtica dioica L.) tokom dana zavise samo od promena temperature. Porast temperature usporava procese u reakcionom centru (RC) i na akceptorskoj strani PIII, što utiče na transport elektrona u PSII, kao i na ukupnu fotosintezu. Slična situacija je zapažena i kod ribizle (Ribes spp.). Zapaženi efekat temperature može se razmatrati kao privremena termalna inhibicija fotosinteze usled diurnalnih promena temperature. Mišljenja smo da je taj fenomen karakteristika ispitivanih biljaka iz jedne planinske ekološke niše, kao i specifičnih uslova merenja.

AB  - Effects of the herbicide sulphosate on growth, accumulation and distribution of dry weight and photosynthesis were investigated in maize plants grown in field conditions and previosly subjected to influence of kinetine, because of potentially protective role of this phytohormone. This phytohormone not protected maize plants from phytotoxic action of herbicide sulphosate, because of inhibition of growth, accumulation and distribution of dry weight and also photosynthesis, irrespective of kind of pretreatment of plants (with or without kinetine).

AB  - Chla fluorescence, as a mode of estimation of photosynthesis, is especially sensitive to changes in temperature and light intensity (PAR). This enables us to study the influence of those ecophysiological parameters on photosynthesis in native plants. In this article, we examined the effect of annual changes in temperature and PAR on the parameters of Chla fluorescence in Stellaria media (L.), a plant species more frequent in colder periods of the year, and Plantago maior (L.), which is more frequent in warmer periods. Lower PAR and temperature slowed down the electron transport in PS2, but lower temperatures reduced the quantum efficacy of PS2 and improved processes in the antennae system and the size of plastoquinone pool of PS2 in Stellaria media (L.). Lower temperatures reduced quantum efficacy and slowed down the electron transport in PS2 in Plantago maior (L.). The facts that PAR (as well as temperature) affects photosynthesis, and that lower temperatures activate processes in the antennae system and those on the acceptor side of PS2 as a 'counterbalance' to the inhibition of quantum efficacy and electron transport in PS2, caused by low temperatures, point at possible explanations of low-temperature resistance of photosynthesis in Stellaria media (L.). On the other hand, low temperatures caused inhibition of quantum efficacy and electron transport in the PS2 of Plantago maior (L.), which caused low-temperature photoinhibition and stepped quenching of all physiological processes in the species. This might be the reason for the different levels of acclimation to low temperatures and different life strategies of the two species living in close vicinity.
AB  - Fluorescencija Chla, kao pokazatelj fotosinteze, posebno je osetljiva na promene temperature i intenziteta svetlosti (PAR). To omogućava praćenje uticaja ovih ekofizioloških parametara na fotosintezu nativnih biljaka. U ovom radu dat je pregled uticaja godišnjih promena temperature i PAR na parametre fluorescencije Chla kod Stellaria media (L.), biljne vrste zastupljenije u hladnijem delu godine i Plantago maior (L.), biljne vrste zastupljenije u toplijem delu godine. Manje vrednosti PAR i temperature usporavaju transport elektrona u PS2, sniženje temperature umanjuje kvantnu efikasnost u PS2 i pozitivno deluje na antenske procese i veličinu pula plastohinona u PS2 kod Stellaria media (L.). Sniženje temperature umanjuje kvantni prinos i usporava transport elektrona u PS2 kod Plantago maior (L.).

abstract = "Chla fluorescence, as a mode of estimation of photosynthesis, is especially sensitive to changes in temperature and light intensity (PAR). This enables us to study the influence of those ecophysiological parameters on photosynthesis in native plants. In this article, we examined the effect of annual changes in temperature and PAR on the parameters of Chla fluorescence in Stellaria media (L.), a plant species more frequent in colder periods of the year, and Plantago maior (L.), which is more frequent in warmer periods. Lower PAR and temperature slowed down the electron transport in PS2, but lower temperatures reduced the quantum efficacy of PS2 and improved processes in the antennae system and the size of plastoquinone pool of PS2 in Stellaria media (L.). Lower temperatures reduced quantum efficacy and slowed down the electron transport in PS2 in Plantago maior (L.). The facts that PAR (as well as temperature) affects photosynthesis, and that lower temperatures activate processes in the antennae system and those on the acceptor side of PS2 as a 'counterbalance' to the inhibition of quantum efficacy and electron transport in PS2, caused by low temperatures, point at possible explanations of low-temperature resistance of photosynthesis in Stellaria media (L.). On the other hand, low temperatures caused inhibition of quantum efficacy and electron transport in the PS2 of Plantago maior (L.), which caused low-temperature photoinhibition and stepped quenching of all physiological processes in the species. This might be the reason for the different levels of acclimation to low temperatures and different life strategies of the two species living in close vicinity., Fluorescencija Chla, kao pokazatelj fotosinteze, posebno je osetljiva na promene temperature i intenziteta svetlosti (PAR). To omogućava praćenje uticaja ovih ekofizioloških parametara na fotosintezu nativnih biljaka. U ovom radu dat je pregled uticaja godišnjih promena temperature i PAR na parametre fluorescencije Chla kod Stellaria media (L.), biljne vrste zastupljenije u hladnijem delu godine i Plantago maior (L.), biljne vrste zastupljenije u toplijem delu godine. Manje vrednosti PAR i temperature usporavaju transport elektrona u PS2, sniženje temperature umanjuje kvantnu efikasnost u PS2 i pozitivno deluje na antenske procese i veličinu pula plastohinona u PS2 kod Stellaria media (L.). Sniženje temperature umanjuje kvantni prinos i usporava transport elektrona u PS2 kod Plantago maior (L.). Činjenica da i PAR (pored temperature) deluje na fotosintezu, kao i da sniženje temperature aktivira antenske i procese na akceptorskoj strani PS2, kao "protivtežu" inhibiciji kvantne efikasnosti i transporta elektrona u PS2, uzrokovanoj niskim temperaturama, ukazuje na moguće uzroke niskotemperaturne otpornosti fotosinteze kod Stellaria media (L.). Nasuprot tome, kod Plantago maior (L.) niska temperatura uzrokuje inhibiciju kvantne efikasnosti i transporta elektrona u PS2, što dovodi do niskotemperaturne fotoinhibicije i postepenog gašenja svih fizioloških procesa kod te vrste.

AB  - The effects of PAR and temperature on induction of Chl a fluorescence were observed on leaves of 20 plant species in their natural environments. Light affects the acceptor side of PS2. Temperature regulation of PS2 activity proceeds by affecting the RC and acceptor side of PS2. The impact of higher temperature can be attributed to greater fluidity of the thylakoid membranes. Photosynthetically active radiation and temperature under the given conditions are in highly significant positive correlation, so it is not clear whether this impact is due to individual or complementary mechanisms of PAR and/or temperature affecting photosynthetic processes in the thylakoid membranes. Also, it is not clear whether species specificity has any significance in the plant photosynthetic response to changes of PAR and temperature. Changes of PAR and temperature during induction of Chl a fluorescence do not affect Pindex, as a parameter of total photosynthesis.
AB  - Praćen je uticaj PAR i temperature na indukciju fluorescencije Chl a na listovima 20 biljnih vrsta u njihovom prirodnom okruženju. Svetlost deluje na akceptorsku stranu PS2. Regulacija aktivnosti PS2 temperaturom odvija se uticajem na RC i akceptorsku stranu PS2. Uticaj povišene temperature moguće je objasniti i povećanom fluidnošću tilakoidnih membrana. PAR i temperatura u datim uslovima nalaze se u visokoznačajnoj pozitivnoj korelaciji, tako da nije jasno da li se radi o posebnim ili komplementarnim mehanizmima dejstva PAR i/ili temperature na fotosintetske procese u tilakoidnim membranama. Takođe nije jasno da li specijska specifičnost ima neki značaj u fotosintetskoj reakciji biljaka na promene PAR i temperature. U ovim procesima promene PAR i temperature ne utiču na Pindex, kao pokazatelj ukupne fotosinteze.
