seeds of different fractions obtained after seed processing and the initial seedling
growth.- Genetika, Vol 55, No.1, 289-300.
The shape and the size of maize seeds are the most variable traits, which are determined
by a genotype and environmental conditions. The aim of this study was to understand the
effects of the mechanism of the relationship and significance of seed variability on
germination and morphology of seedlings. The seeds of five hybrids ZP388, ZP434,
ZP555, ZP606, and ZP6263 were used in this study. The following seed traits were
analysed: physical ones: seed length (L), thickness (T) and the width (W); morphological
ones: seed weight (SW), seedling length (SLW), root length (RL), shoot length (SL) and
seed germination (G) as a phydiological trait.There are statistically significant differences
not only among physical traits of the seeds of the five hybrids (p≤0.05), but also among
the morphological traits (p≤0.05). Statisticlly significant differences (p≤0.05). in the

width (W), length(L) and thickness (T) of seeds of all hybrids were determined in the
small flat fraction (SP). The large rounded seed fraction (KO) mainly differed in the
width and thickness between hybrids ZP434 and ZP 555, while the large flat seed fraction
differed the most in the length between these two hybrids. Large-flat (KP) seed fractions
are also characterized by the highest germination (99%). As the seed weight increases, the
seedling weight decreases (R2=0.527). Segmentation within hybrids according to the
diversity of morphological and physiological properties of seeds was carried out
according to the seed size, fraction and seedling weight, while the other parameters were
less important. The characteristic of all hybrids is that large seeds of the KP fraction have
high germination and well-developed seedlings., Oblik i veličina semena kukuruza su najpromenljivije osobine koje određuju genotip i uslovi
životne sredine. Cilj ovog istraživanja je bio da se sagleda značaj varijabilnosti semena i njen
odnos sa klijavošću semena i morfologijom klijanaca. U radu je korišćeno seme pet hibrida
ZP388, ZP434, ZP555, ZP606 i ZP6263. Analizirane su sledeće osobine semena: fizičke: dužina
(L), debljina (T) i širina (V); morfološke: masa semena (SV), dužina semena (SLV), dužina
korena (RL), dužina izdanka (SL) i klijavost semena (G) kao fiziološka osobina.Postoje
statistički značajne razlike ne samo među fizičkim osobinama semena pet hibrida p≤0,05) već i
među morfološkim osobinama (p≤0,05). Statistički značajne razlike (p≤0,05). širina (V), dužina
(L) i debljina (T) semena svih hibrida su određene u sitno pljosnatoj frakciji (SP). Frakcija
krupnog okruglog semena (KO) se uglavnom razlikovala po širini i debljini između hibrida
ZP434 i ZP 555, dok se frakcija krupnog plosnatog semena najviše razlikovala po dužini između
ova dva hibrida. Krupno-plosnata (KP) frakcija semena takođe se odlikuju najvećom klijavošću
(99%). Sa povećanjem mase semena, težina semena se smanjuje (R2=0,527). Selekcija unutar
hibrida prema raznovrsnosti morfoloških i fizioloških osobina semena vršena je prema veličini
semena, frakciji i masi semena, dok su ostali parametri bili manje važni. Karakteristika svih
hibrida je da krupno seme KP frakcije ima visoku klijavost i dobro razvijene klijance.",
