摘　　要：选择3个不同产量水平的9个栽培大豆(Glycine max(L.)Merr.)品种,在相同的环境条件下种植,用LI-6400型光合作用测定系统,测定不同生育时期大豆叶片的净光合速率,用常规方法测定叶片叶绿素含量和比叶重。结果表明,高产大豆品种叶片比叶重、叶绿素含量和净光合速率均高于低产大豆品种。大豆产量与叶片净光合速率之间呈显著正相关。由于现代技术手段的改进,可方便地进行叶片净光合速率的瞬时、准确测定,因此可以把净光合速率作为选择高产大豆品种的一个有效指标。Total nine soybean （Glycine max （L.） Merr.） cultivars divided into three yield levels were planted under the same environmental condition.The net photosynthetic rate was measured by LI-6400 portable photosynthesis system;the chlorophyll content and the specific leaf weight were measured with the regularmethod.The results showed that the specific leaf weight,chlorophyll content and net photosynthetic rate of high yield varieties were higherthan those of low yield varieties.The yield had a significantly positive correlation with the net photosynthetic rate.As the results of modern technology improvement,the net photosynthetic rate could be measured quickly and exactly,as the selection index of high yield soybean,the netphotosynthetic rate would be putinto effective use in soybean breeding in the future.
