AB  - Seed vigor is the quality parameter which indicates germination under wide range of 
environmental conditions. This trait can be identified by standard germination test as so-called 
first count germination or germination energy. In addition, several tests for vigor evaluation 
were adopted by seed testing associations such as ISTA and AOSA. The main purpose for 
developing additional vigor tests is to obtain fast and reliable information on seed vigor which 
contributes to decision making in the inventory management. ISTA rules prescribes several 
tests for evaluating seed vigor, namely: conductivity test, accelerated ageing (AA) for soybean, 
controlled deterioration for Brassica seeds, Radicle emergence (RE) and Tetrazolium (TZ) 
vigor test for soybean. Seed testing laboratory of the Maize Research Institute is accredited by 
ISTA for RE vigor test, has internally developed cold-test and is capable for application of TZ 
vigor test for research purposes. These tests were applied on several maize seeds lots with 
declining germination energy and still highly rated final germination. Results of vigor tests 
were correlated with the standard germination quality parameters, germination energy and final 
count, in order to identify vigor test which provides the most approximate output to the standard 
germination test. Correlations were significant for all vigor tests, in average 0.882 and 0.713 
for germination first and final count, respectively. The highest compatibility between vigor and 
germination tests was identified for cold test with correlation coefficients of 0.952 and 0.839 
for germination first and final count, respectively. However, due to duration of cold test (2 
weeks), it is not capable of providing fast information. Therefore, other two vigor tests, TZ and 
RE, which are shorter and have high correlation with germination energy (0.901 and 0.811, 
respectively) and final count (0.713 and 0.728, respectively) can be recommended for this 
purpose.

AB  - Accuracy and random selection of seeds when testing the 1000 seeds weight in the laboratory is of great importance in order to ensure the representativeness of the sample and precise information for further packaging process. The aim of this research was to check whether the laboratory seed counter selects seeds by shape and size and whether there is a trend during operation at maximum and reduced speed. Ten species of different seed sizes were used. Ten replicates of 100 seeds were counted by counter, the number of seeds was manually checked and the weight measured. The analysis of the obtained results showed that the counter is precise, but weight results showed selection of smaller seeds (Capsicum annuum and Glycine max) at maximum counting speed. Trend of larger seed selection was observed in Medicago sativa and pelleted Beta vulgaris. Slower counting (50% of the maximum speed), is ensured precise counting without trends.
AB  - Praćenje i kontrola rada laboratorijske opreme je jedan od zahteva akreditacionih standarda za laboratorije za ispitivanje
semena. U dosadašnjoj praksi nije se obraćala pažnja da li prilikom rada brojača dolazi do selektivnog izbora semena koje se broji.
Preciznost i slučajan izbor semena kod ispitivanja mase 1000 semena u laboratoriji je od velike važnosti kako bi se obezbedila
reprezentativnost uzorka. Cilj ovog istraživanja je provera da li laboratorijski brojač semena u toku svog rada, pri maksimalnoj i
smanjenoj brzini selektuje seme po obliku i veličini i da li postoji trend. U radu je ispitivano 10 vrsta različite krupno će semena
(Capsicum annuum, peletirano seme Beta vulgaris, Brassica napus, Medicago sativa, Raphanus sativus, Sinapis alba, Triticum
aestivum, Helianthus annuus, Glycine max i Zea mays). Analizom dobijenih rezultata utvrđeno je da brojač precizno broji. Na osnovu
rezultata izmerene mase uočeno je da se na maksimalnoj brzini brojanja pojavljuje trend selektovanja prvo sitnijeg, a zatim krupnijeg
semena kod vrsta Capsicum annuum i Glycine max. Nasuprot tome, kod semena Medicago sativa i peletiranog semena Beta vulgaris,
uočen je trend selektovanja semena od krupnijeg ka sitnijem. Prilikom sporijeg brojanja (50% od maksimalne brzine), postiže se
slučajan odabir semena tj. ne pojavljuje se trend prilikom rada brojača, kod gore navedenih vrsta semena. Za ostale vrste nije uočen
trend postepenog smanjenja niti pove ćanja vrednosti mase u okviru ispitivanih 10 ponavljanja. Rezultati ovih analiza ukazuju na
važnost provere opreme kako u smislu tačnosti brojanja tako i selektovanja semena u cilju dobijanja tačnih rezultata ispitivanja mase
1000 semena.

AB  - The aim of this study was to determine variability of temperature sums for the occurrence of
pheno-phases of silking, tasselling and pollination of seed maize. Nine maize inbred lines
were tested in two production years. Compatibility and overlapping of silking, tasselling and
pollination of parental components in a seed crop are important for achieving high yields.
According to obtained data, the degree of accumulation of temperature sums was higher in the
first year than in the second production year for all stages, except for the beginning of
tasselling. The differences were statistically significant: the greatest and smallest differences
were obtained for tasselling (t2 - 70.9oC) and the beginning of silking (s1- 20.86oC),
respectively. The effect of genotypes on differences in temperature sums was the greatest for
all pheno-phases, p<0.005. The effect of the production year on the number of temperature
units necessary for silking and pollination was also high, but there was no high statistical
effect on the beginning of tasselling. Since maize is a plant species that is grown in different
regions, maize growing practices should be adjusted to the main aim of maize production, to
achieving high and stable yields.
