摘要
在群体条件下，扁茎大豆（中国扁茎）结荚鼓粒期光合特性为：光合速率高于高产品种黑农３７，与高光效品种黑农４０相仿；具有高于黑农３７和黑农４０的单株叶面积，截获光能能力强；形成较多光合产物，并能有效地运往茎和花荚中，从而获得高于黑农３７和黑农４０的单株产量。这些光合特性有利于对其进行高光效育种改良。因此我们认为扁茎大豆可以做为高光效育种种质资源加以改造利用。
Under population condition, photosynthetic properties of fasciated stem soybean (Chinese Fasciated Stem) at pod setting and pod filling stages were measured and compared. The results were that photosynthetic rate of fasciated soybean was higher than high-yield variety, Heinong 37, and similar to high photosynthetic rate variety, Heinong 40; there was a larger leaf area per plant in fasciated stem which represented a strong ability of obtaining sunlight; more photosynthate was synthesized and transported effectively into stem, flowers and pods, so that higher yield could be achieved. These photosynthetic properties are useful to improve soybean by breeding.
