| 摘 要： | 为了探讨阴生植物在遮荫条件下的光合特性,以12种阴生园林植物为试材,对其在不同光照条件下的净光合速率日变化、日平均净光合速率、表观量子效率及光补偿点进行比较研究.结果表明:植物净光合速率日变化随光照条件的不同而发生改变,当光强较弱时,植物的净光合速率日变化由双峰曲线变为单峰曲线;在一定光照条件范围内,日平均净光合速率及表观量子效率随着遮荫度的增大而增强,在某一遮荫度条件下达到最大值,此后则随遮荫度增加而递减;植物在不同光强环境下的光补偿点随着遮荫度的增加而减小.方差分析表明,不同光照处理对12种植物各光合指标的影响均达极显著差异.适度遮荫有利于阴生植物生长和光合性能的提高. |

| Abstract: | Twelve species of shade plant were used to study the photosynthetic characteristics under sun-shading conditions.The net photosynthetic rate change,average net photosynthetic rate,apparent quantum yield and light compensation point was investigated under different sun shading conditions.The results showed that the photosynthetic characteristics changed under different shading treatments.When the sun light was weak,the net photosynthetic rate varied from a two-peak curve to a single-peak one,which only happened under a certain sun-shading degree.With the increase of sun-shading degree,the daily average net photosynthetic rate and the apparent quantum yield increased to a peak,and then fell down while the light compensation point decreased continuously.There were extremely significant differences for each index of photosynthetic characteristics among 12 species of shade plant under different sun-shading treatments.Proper sun-shading is beneficial to the growth of shade plant and improvement of photosynthetic characteristics. |
