| 摘 要： | 运用CB-1102型光合蒸腾作用测定系统,研究了芸豆鼓粒期的净光合速率（Pn）日变化。结果表明：芸豆叶片净光合速率（Pn）日变化呈单峰型曲线,无光合午睡现象。上午10：00光合速率最大;11：00蒸腾速率最快;气孔导度的变化趋势与光合速率一致,10：00出现最大值;胞间CO2浓度呈现“早晚高,中间低”的变化规律。

| Abstract: | With CB-1102 Portable Photosynthetic System,the net photosynthetic rate of kidney bean leaf was studied at Seed filling stage.The results showed that daily changes of net photosynthetic rate of kidney bean presented a unimodal curve and no depression was observed at midday.photosynthetic rate reaches maximum at 10 o＇clock;The transpiration rate were highest at 11 o＇clock;The value of stoma conductance reaches it＇s peak at 10 o＇clock; |
| |
| Keywords: | kidney bean net photosynthetic rate transpiration rate value of stoma conductance intercellular CO2 concentration daily changes |
