| 摘 要： | 在抗虫鉴定的基础上,对大豆抗食心虫品种(系)的抗性机制进行了研究。发现豆荚硅元素含量高是抗虫的主要原因之一;豆荚表皮细胞呈近圆形突起、直径小或表皮细胞下小细胞层数多、表皮下有特长形细胞者;豆荚隔离层细胞呈短椭圆形、直径小、排列紧密者均有较强抗性。抗性与荚皮厚度、隔离层厚度及隔离层细胞排列方向无关。

| Abstract: | On the basis of evaluation for the soybean resistaccc to soybean pod borer, the resistance mechanism of different soybean varieties were studied. It was found that resistance against pod borers mainly derives from the high content of silicon in the pod. The resistant soybean varieties also have the following characters.The epidemis cells of the bean pod were small quasi-round protuberances. Under the epidemis cells, there were either many layers of smaller cells, or longer cells. The segregation layer cells, of the bean pod, in the small elliptical shape and arranged closely, demonstrated strong resistance. The resistance had no relation with the thickness of the pod,the thickness of the segregation layer, and the direction of arrangement of the segregation cells. |
