| 摘 要： | 测定12个品种大豆叶片全氮含量(％)表明:各节位叶片全氮含量总平均值为4.51％。从初生叶到11—12节位叶片随节位上升,全氮含量逐渐增加。5—6、7—8、9—10节位叶片全氮含量与总平均值呈显著正相关。早熟品种植株12节位以下叶片的各节位叶片全氮含量的平均值高于晚熟品种。

| Abstract: | A comparative study of N percentage was made on leaves at different nodes of 12 soybean (Glycine max (L.) Merrill) cultivars. The N percentage was high in the leaves at 5-12 th nodes of main stem. Early maturing cultivars had higher N percentage than late ones. The mean values of N percentage in early and late maturing cultivars were 4.64% and 4.46% respectively. A positive correlation was found between N percentage in leaves at 5-8 th nodes of early maturing cultivars and the mean value of percentage of all leaves, as well as between the leaves at 7-10th nodes of late maturing cultivars and the mean value of all leaves. |
