| 摘 要： | 利用单因素完全随机试验,开展了相同品种不同粒重大豆幼苗根系活力变异研究。结果表明:嫩丰16和东农42两个大豆品种不同粒重幼苗根系体积、总吸收面积、活跃吸收面积间存在极显著差异;籽粒越大幼苗根系体积、总吸收面积、活跃吸收面积越大,说明不同粒重对幼苗根系活力性状有极显著的影响。

| Abstract: | The variance on the seedling root activities of different seed weight from the same soybean variety was studied by completely random design. The result showed that there were very significant variation among the volumes, total absorbing areas, living absorbing areas of seedling roots from different seed weight of soybean varieties Nenfeng 16 and Dongnong 42. The volumes, total absorbing areas, living absorbing areas of seedling roots get the larger, the bigger the seed is. It indicated that the effect of different seed weights from the same soybean variety on the seedling root activities was very significant. |
