Sažetak
Seme kukuruza odlikuje se raznovrsošću oblika i veličina, koje po srednoilineposrednoutičuna fiziološke osobine. Ciljrada je bio da se utvrdi značaj oblika i veličine semenana energiju I klijavost semena. U ogledu kao semenski material korišćeno je osam hibrida (ZP196, ZP260, ZP341, ZP360, ZP434, ZP 677, ZP684, ZP704. U laboratorijskim uslovima posmatrane su osobine oblika i veličine seme. Izvojeno je četiri frakcija SP. SO. SSP, SSO. Od osobina određena je masa semena, energija klijanja, klijavost. Genotip i frakcija semena imale su značajnog uticaja na varijansu formiranja mase semena R2 ≥0,911, dok za energiju i klijavost značaj ovih faktora je Mali sa koeficijentom determinacije R2 ≤0,129 odnosnoR2 ≤0,298. Struktura semena na klipu podeljena u frakcije ukazuje na veće prisustvo sinih frakcija u odnosu na srednje sitne, a po obliku ujenačenije su pljosnate frakcije, izmeđukojih ne postoji statistička značajnost. Energija klijanja i klijavost semena kod svih veličina i oblika semena je visoka iznad 95%. Najmanja energija i klijavost je za seme SO (94,2; 95,1), a najveća za seme SSP (97,1;98,0).Istraživanja su pokazala da podele semena po frakcijama ima značaja radi ujednačavanja semenskog materijala i jedan je od osnovnih uslova za dobru semensku i merkantilnu proizvodnju. Naročito je značajno u prvim fazama razvitka klijanaca, što kasnije ima uticaja na prinos useva.
