【摘要】 以3个微胚乳超高油玉米自交系干种子为材料,用不同剂量的γ-射线进行辐射,对辐射当代苗高的影响进行研究。结果表明:在所使用的剂量范围内,辐射当代苗高降低,随着辐射剂量的增加降低越明显。根据苗高降低的程度确定该类型玉米自交系干种子的适宜辐射剂量大致为120～180Gy。更多还原

【Abstract】 Dry seeds of three micro-endosperm super-high oil corn inbred lines were irradiated by different γ-ray dose; the effects on seedling height of F1 generation were studied. The results showed that in the used range of irradiation dose, seedling height were declined, and the more irradiation dose increased, the more declined. According to the decline extent of seedling height, ascertained the proper irradiation dose to dry seeds of inbred lines from these kinds of corn was about from 120 to 180 Gy.更多还原
