| 摘 要： | 在自然生长条件下测定了野生苋菜的光合速率和蒸腾速率及环境因子的日变化规律,并分析了光合速率、蒸腾速率与环境因子的相关性。结果表明:光合速率和蒸腾速率的日变化呈"单峰"曲线,光合速率的峰值出现在12:00左右,蒸腾速率的峰值比光合速率的峰值晚2 h,出现在14:00左右。苋菜的Pn与PAR、Ta、Gs呈极显著的正相关(P<0.01),与Ca呈显著的正相关(P<0.05),与RH呈负相关。苋菜的Tr与Ta呈极显著的正相关(P<0.01),与RH呈极显著的负相关(P<0.01),与PAR、Gs、Ca呈显著的正相关(P<0.05)。

| Abstract: | In nature growing,the diurnal dynamics of photosynthetic rate(Pn) and transpiration rate(Tr) of edible amaranth,and environment factors,and analyzed correlation between photosynthetic rate or transpiration rate in leaves of edible amaranth and environment factors.The results showed that the curves of diurnal variation in Pn and Tr of edible amaranth leaves had one peaks,but there were differences in the time and the value of the peaks occurred in terms of Pn and Tr,the time of the peaks of Pn was at 12:00 o... |
