Wheat seed quality as affected by grain size

Abstract

Four seed fractions of winter wheat were analyzed ( lt 2.2 mm, 2.2-2.5 mm, 2.5-2.8 mm, and >2.8 mm). Thousand-grain weight, germination energy and total germination were tested under laboratory conditions. The average value of 1000-grain weight increased with increasing seed size. On average, the most and least abundant fractions were >2.8 mm (43.2%) and 2.2-2.5 mm (9.2%), respectively. The highest percentage of germination (94%) was found in the lt 2.5-2.8 mm and 2.2-2.5 mm fractions and the lowest in the lt 2.2 mm one.

Analizirane su četiri frakcije semena ozime pšenice lt 2,2mm, 2,2-2,5mm, 2,5-2,8mm i >2.8mm. U laboratorijskim uslovima ispitana je masa 1000 zrna, energija klijanja i ukupno klijanje. Prosečna vrednost mase 1000 zrna se povećava sa povećavanjem krupnoće semena. Rezultati su pokazali da je u proseku najveći udeo zrna imala frakcija gt 2,8mm od 43,2%, a najmanji frakcija 2,2-2,5mm sa udelom od 9,2%. Najveći procenat klijanja 94% bio je kod frakcije lt 2,5-2,8mm i 2,2-2,5mm, a najmanji 87% kod frakcije lt 2,2mm.
