Sažetak
Ispitivan je uticaj skladištenja na kvalitet i stanje semena ovsa za tri sorte (Dinav, Vrbas i NS Tara) koje su selekcionisane u Srbiji. Sveže požnjeven ovas je uskladisten na 25±2°C na 12 i 20 meseci. Zabeležen je značajan pad vrednosti zapreminske 458.4-408.9 kg m-3 i apsolutne mase 26.6 - 24.2% tokom skladištenja semena ovsa. Sa dužinom vremena skladištenja smanjivalo se biološko svojstvo semena na sposobnost klijavosti 96.2-94.1%. Promene kiselinskog stepena (3.77-3.99 ml 1(Na OH)/100 g) su statistički veoma značajne (p<0.01). pH vrednost svežih uzoraka semena je bila 6,2 a nakon 20 meseci 5,8. Dužina skladistenja nije značajno uticala na svojstvo staklavosti. Genotip i zapreminska masa imaju visok uticaja na dužinu skladištenja (η2=0.8130 η2 =0.7621 i η2=0.6780). Interakcija ispitivanih faktora nije ispoljila statistički značajan uticaj na promenu stepena klijavosti semena ovsa (p>0.05). Dužina skladištenja semena ovsa najviše doprinosi porastu vrednosti kiselinskog stepena, a nešto manje genotip, kao i interakcija ovih faktora. Testirani genotipovi ovsa nemaju značajne razlike u pogledu staklavosti semena (p>0.05).
