Abstract:

To investigate the effect of leaf source on photosynthetic characteristics and yield in multifoliolate soybean,the multifoliolate soybean strain Mu 5796-3 was selected as material and five treatments of removing the extra two leaflets at different growth stages were set in this study.The results showed that the difference of chlorophyll content at R6 stage among treatments didn’t reach significant level.The net photosynthetic rate (Pn),leaf area per plant and leaf area index (LAI) of not removing the extra leaflets(T5) were significantly higher than those removing the extra leaflet at whole growth periods(CK).Thereby leading to the increase of seed number per plant and 100-seed weight,increased seed yield of T5 treatment.Considering the better agronomic and yield performance of soybean strain Mu 5796-3,it could be used as parent in soybean breeding.
