| 摘 要： | 本文分别在盆栽及大田条件下对中国扁茎大豆不同叶位叶片的空间分布、叶片大小及光合生理特性进行了研究。结果表明，扁茎大豆主茎上叶片的数量明显多于普通型大豆，是普通型大豆的２．２倍，且在主茎上的分布不均匀，上部叶片较为密集。不同生育时期，其光合速率最大的叶片比普通型大豆偏下。上部叶片较小且光合速率较低。同一轮的叶片间光合生理参数也明显不同。

| Abstract: | The distribution, size and photosynthetic properties of leaves at different leaf positions of Chinese fasciated stem soybean were studied under pot and field conditions. The result shows that the number of leaves on main stem of fasciated stem soybean is obviously larger than (2.2 times) that of common soybeans. The distribution of leaves on main stem of fasciated stem soybean is not even, with more leaves on the upper part. The leaves with the greatest photosynthetic rate are lower an position than those of common soybean. The upper leaves are smaller and with lower photosynthetic rate. The photosynthetic physiological properties of leaves on the same verticil are also different. |
