AB  - The aim of this study was to observe direct and joint effects of three factors (genotypes,
ecological environmental conditions and the applied crop density) on the level of defoliation intensity
and yield. Three inbred lines (G) of maize (G1–L217RfC, G2–L335/99 and G3–L76B004) were used
in the study. The trials were performed in two years (Y) (Y1 = 2016 and Y2 = 2017) and in two
locations (L) (L1 and L2) under four ecological conditions of the year–location interaction (E1–E4)
and in two densities (D1 and D2) (50,000 and 65,000 plants ha−1
). Prior to tasselling, the following
five treatments of detasseling and defoliation (T) were applied: T1—control, no leaf removal only
detasseling, T2–T5—removal of tassels and top leaves (from one to four top leaves). The defoliation
treatments had the most pronounced effect on the yield reduction in G1 (T1–Tn+1 . . . T5), p < 0.05.
The ecological conditions on yield variability were expressed under poor weather conditions (E3 and
E4), while lower densities were less favorable for the application of defoliation treatments. The result
of joint effects of factors was the lowest grain yield (896 kg/ha) in G3 in the variant E3D1 for T2 and
the highest grain yield (11,389 kg/ha) in G3 in the variant E2D2 for T1. The smallest effect of the
defoliation treatment was on the kernel row number (KRN)

AB  - Od frakcionog sastava semena zavisi tehnologija dorade. Uvođenje novih i
poboljšanih rešenja u doradi hibridnog semena kukuruza doprinosi poboljšavanje osobina
tog semena radi ispunjavanja agrotehničko-tehnoloških zahteva u proizvodnji merkantilnih
useva. Cilj rada je da se utvrdi procentualno učešće četiri osnovne frakcije semena (sitno
okrugla SO, sitno pljosnata-SP, srednjesitno okrugla-SSO, srednje sitno pljosnata-SSP) u
sastavu semenskog materijala, njihovo variranje u odnosu na lokaciju proizvodnje i njihov
uticaj na klijavost i energiju klijanja. Materijal koriščen u istraživanju su četiri genotipa iz
FAO grupe 100 i 200, ZP196, ZP 209, ZP256 i ZP 260. Podela materijala na frakcije urađena je
u laboratorijskim uslovima, kao i ocena energije i klijavosti semena. Rezultati su pokazali da
je najzastupljenija frakcija kod tri hibrida SO (ZP196, ZP 209, ZP256), a kod četvrtog ZP 260
je SSO frakcija. Procenat zastupljenosti pojedinih frakcija kreće se od 14,9% za SSP frakciju
do 54,3% za SSO frakciju. Ovaj procentualni odnos bitno se nemenja u odnosu na lokaciju
proizvodnje. Klijavost i energija kod svih posmatranih hibrida i frakcija bila je visoka, iznad
90%. Veća odstupanja između energije i kljavosti semena zabeležena su jedino kod SSO
frakcije semena.
Analiza dobijenih rezultata ukazuje da se pravilnom tehnologijom dorade i
poznavanjem odnosa frakcija hibrida koje uvodimo u proizvodnju omogućuje maksimalno
koriščenje potencijala koje nam pruža genotip.
AB  - Processing methods depend on the composition of seed fractions. The introduction of
new and improved solutions in processing of hybrid maize seed contributes to the
improvement of such seed in order to satisfy requirements of cropping and growing
practices of commercial crop production. The objective of this study was to establish the
percentage share of four basic seed fractions (SO, SP, SSO, SSP) in the seed material, their
variation over production locations and their influence on 1000-kernel weight, germination
and germination energy. Four genotypes of the FAO maturity groups 100 and 200 (ZP196, ZP
209, ZP256 and ZP 260) were used as the material in the study. Distribution of materials on
fractions was performed in the laboratory, as well as the assessment of energy and seed
germination. The results showed that the SO is most frequent fraction in three hybrids
(ZP196, COP 209, ZP256), while SSO is most common in the fourth NG 260 CSF. The
percentage share of certain fractions ranged from 14.9% for the SSP fraction to 54.3% for the
CSF fraction. This percentage ratio does not change significantly in relation to the location of
production. Germination and energy of all observed hybrids and fractions was high, over
90%. Larger discrepancies between energy and seed germination were recorded only at SSO
seed fraction. Analysed results schow that the potential of a genotype will be maximally used, if the fraction ratios of hybrids introduced to the production is known and if the proper processing is applied.
