AB  - Five direct and reciprocal early hybrids, five direct and reciprocal late hybrids and a total
of their 12 parental inbred lines were used in order to test reciprocal effects among
hybrids in early germination phase and seed quality of their parental inbred lines. Five
hybrids were of early maturity FAO 300-400 group, and five of late maturity FAO 500-
600 group. In the early group one line of Lancaster origin (L1) was in common, and in
direct crosses used as male parent, while in reciprocal crosses as female parent. The same
case was with late hybrids where another Lancaster line (L2) was in common. In 2015
and 2016 all the material was multiplied in hand pollination and after six months of
storage three tests according to ISTA standards were performed: standard germination test
(SGT), cold-test (CT) and vigor radicle test (RE). According to the Analysis of variance,
a strong reciprocal effect was found among early hybrids for four out of five parameters
in RE and SGT, while it was found only for RE in late hybrids. However, in CT none of
the parameters had significant reciprocal effect. Two tested Lancaster inbreds were
superior in the hybrids over non-Lancaster lines when used as maternal components,
while as lines per se they did not display such superiority. Mid-parent heterosis (MPH)
ranged from -62.32% to 211.11% in RE test, with an average of 44.26%; from -10.15% to
17.93% in SGT test, with an average of 6.27%, and from -5.31% to 4.49% in CT, with an
average of 0.64%. Significant differences of MPH were found for nine pairs of reciprocal
hybrids for RE, three pairs for SGT and seven pairs for CT. This shows that reciprocal
differences in MPH were higher as the applied level of stress during early seed growth
raised. All the results showed very complicated mode of inheritance of tested traits in the
early developmental stages of young plants, including the phenomenon of heterosis which
is expressed already at the germination stage.

AB  - Praćenje i kontrola rada laboratorijske opreme je jedan od zahteva standarda za laboratorije za 
ispitivanje semena. Period i način kontrole zavise od učestalosti korišćenja opreme, njene strarosti itd. U Laboratoriji za ispitivanje semena Instituta za kukuruz „Zemun Polje“, brojač semena koristi se u ispitivanju mase 1000 semena radi ubrzanja procesa rada i jednom godišnje se redovno proverava njegova tačnost brojanja. Međutim, 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 i ispravno donela odluka o daljem procesu pakovanja. Određivanje mase semena prema ISTA Pravilima se može izvesti na dva načina: brojanjem cele frakcije čistog semena i brojanje ponavljanja od po 100 semena. U oba slučaja brojanje se može izvesti ručno ili korišćenjem brojača. Cilj ovog istraživanja je provera da li laboratorijski brojač semena u toku svog rada, u zavisnosti od brzine, selektuje seme po obliku i veličini i da li postoji trend. U radu je ispitivano 10 vrsta različite krupnoće semena (Capsicum annuum, peletirano seme Beta vulgaris, Brassica napus, Medicago sativa, Raphanus sativus, Sinapis alba, Triticum aestivum, Helianthus annuus, Glycine max i Zea mays). Brojač je podešen na dve brzine brojanja (maksimalna brzina automatski zadata i 50% od maksimalne brzine). Brojano je 10 ponavljanja po 100 semena. Posle svakog ponavljanja izbrojanog na brojaču, ručno je proveravan broj semena i merena je masa. Analizom dobijenih rezultata utvrđeno je da brojač precizno broji, a na osnovu rezultata izmerene mase uočeno je da se na maksimalnoj brzini pojavljuje trend prilikom rada brojača kod vrsta Capsicum annuum i Glycine max (selektovanje semena od sitnijeg ka krupnijem). 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), ne pojavljuje se trend prilikom rada brojača, kod gore navedenih vrsta semena. Za ostale vrste nije uočen trend (proseci mase 1000 semena za obe posmatrane brzine su skoro identični). 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  - 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), ensured precise counting without trends.

AB  - Standard laboratory germination seed test provides information on seed performance under defined environmental conditions aiming to estimate field planting value. Purpose of this study was to compare results from the standard germination test with seedling emergence in different outside temperature conditions. Sowing was done in three periods during spring, in trays exposed to outside conditions. Data obtained showed that differences in the germination, detected in the standard laboratory test, were also confirmed in field conditions. Expression of these differences, however, was dependent on temperature conditions during different sowing periods. Low temperatures during the early sowing were more discriminative than later temperature increase which completely reduced differences detected in the standard germination test.
