以蔓生长豇豆锦穗白豆角和新青青豆角为试材，研究其生长动态、叶面积形成、净同化率（ＮＡＲ）和豆荚产量形成等。结果表明，两个品种生育过程中植株和各个器官的生长动态均呈Ｓ形曲线变化。锦穗白豆角的生长量和叶面积都比新青青豆角大。两品种的ＮＡＲ在营养生长过程都较低，生殖生长过程则提高。新青青豆角的ＮＡＲ比锦穗白豆角稍高。两个品种的结荚能力和豆荚产量无明显差异，豆荚产量形成呈Ｓ形曲线变化。
The results showed that the growth dynamics, the formation of leaf area, the net assimilation rate (NAR) and the pod yield formation were studied by taking the vine as the starting material. The results showed that the growth dynamics of plants and organs showed a S-shaped curve during the growth of two cultivars. Spike white beans growth and leaf area are larger than the new green beans. The NAR of both cultivars was lower in vegetative growth and increased in reproductive growth. The fresh green beans NAR than the spikelets slightly higher. There was no significant difference in pod yield and pod yield between the two cultivars, and the pod yield changed in a S-shaped curve.
