| 摘 要： | 通过对罗望子的光合速率、气孔导度及其相应环境因子的测定,探讨元谋干热河谷罗望子旱季的光合生理生态特征.结果表明,罗望子旱季的光合速率Pn日变化曲线呈单蜂型,无光合"午休"现象发生.Pn与PAR、Tr呈极显著正相关,与RH呈极显著负相关.对Pn影响最大的因子PAR,其次是RH、Tr、Gs、VPD.罗望子在元谋干热河谷有较强的适应性.

| Abstract: | In order to analyze the photosynthesis characters of Tamarindus indica L.in dry-hot valley,the Pn,Gs and other indexes were studied in the dry season in Yuanmou county.The results showed that the diurnal course of Pn presented a single peak curve and did not showed the midday depression of photosynthesis.There was a positive correlation between Pn and PAR,the same correlation between Pn,Tr,Gs and VPD.There was a negative correlation between Pn and RH.Pn was more affected by PAR than other factors.In sum the... |
