摘要
通过去子叶试验研究了子叶对大豆植株主长发育及产量的影响。去掉一片或两片子叶抑制根系的生长,降低叶面积和干物质重量,影响产量及产量构成因素。
Effects of soybean cotyledons on plant growth and yield were studied by removing one or two cotyledons.The results showed that the removal of one or two cotyledons inhibited root growth,then retarded leaf extension,decreased leaf area,dry matter,yield and yield components.It is an effective practice of increasing yield to protect soybean cotyledons in seedling stage.
