Projekat

Unapređenje proizvodnje kukuruza i sirka u uslovima stresa (MPNTR - 31073)

Sažetak

Cilj ovog ispitivanja bio je da se kod partija semena sa različitim udelom atipičnih ponika ispitaju parametri brzine klijanja u polju, broj biljaka u reproduktivnoj fazi i prinos. Ovakvi ponici se u standardnom testu klijavosti ne ubrajaju u klijava zrna, jer se pretpostavlja da neće dati normalnu biljku. Testirano je pet partija hibrida NS 640 sa različitim udelom atipičnih ponika. Rezultati su pokazali da je u povoljnim uslovima veliki broj atipičnih klijanaca nikao, dostigao reproduktivnu fazu i učestvovao u formiranju prinosa. Sa druge strane, nicanje partija sa velikim brojem atipičnih klijanaca je bilo usporeno. Laboratorijska klijavost i energija klijanja su bile u većoj korelaciji sa parametrima brzine nicanja, dok je ukupna klijavost (normalni i atipični klijanci) bila u većoj korelaciji sa prinosom. Ipak, u nepovoljnim uslovima spoljašnje sredine, atipični klijanci imaju manje šanse da se razviju u normalnu biljku.
