Germination of maize hybrids seed stored after harvest.

In this investigation used three maize hybrids that are belongs to different group of ripening: \nFAO 3, FAO 4 and FAO 6. The seed of those hybrids used for investigation of genotypic \ndivergences for seed germination, energy of germination, content of abnormal emergence of \nseeds, content of dead seeds. Hybrid seed for analysis produced on the experimental field of \nthe Institute of Maize in Zemun Polje, Belgrade. The viability of the maize hybrids seeds were \ndetermined in experimental analysis carried out in laboratory for quality of seed in the Maize \nResearch Institute Zemun Polje, Belgrade. According to standard method on filter paper were \nestimated the values of seed germination. The three experiment of seed germination carried \nout: 2 months after harvest, 9 months after harvest and 18 months after harvest. In average \nfor each test the highest percentage of seed germination were found for hybrid ZP FAO3: \n92.75% for seed after 2 months of harvest, 92.00% for seed 9 monhts after harvest and \n91.50% for seeds after 18 months of harvest. This hybrid had the lowest percentage of \nungerminated seeds (2.75%) and the least content of dead seed (~5.00%). The lowest value of \nseed germination (86.33%) and the highest values of ungerminated seed (~3.00%) as well the \nhighest content of dead seed (10.33%) had hybrid belongs FAO 4 group. The obtained results \nindicate differences of germination in analyzed maize genotypes.
