摘  要:
采用Li-6400便携式光合作用测试系统对6个类型的流苏的光合生理指标进行了测定。结果表明,(1)类型四的光合速率日变化呈"双峰型"曲线,类型一、二、三、五、六呈"单峰型"曲线。(2)6个流苏类型的各个光合指标除去Gs均存在极显著的差异。(3)类型六光合能力最强,对光的适应力也很强,Tr稍大,所以在水分充足的情况下可能会生长得更好。

摘  要:
Photosynthetic and physiological index of 6 types of Chionanthus retusus were measured by using portable LI-6400 Photosynthesis System( LI-COR). The results showed that,( 1) The net photosynthetic rate of type IV had a bimodal pattern and had a clear midday depression. The net photosynthetic rate of type Ⅰ,Ⅱ,Ⅲ,ⅤandⅥ had a unimodal pattern;( 2) There were significant differences in photosynthetic indexes among these 6 types of Chionanthus retusus except for Gs;( 3) Type VI had the best photosynthetic capacity with better ability for adapting different light density,therefore it could grow better with enough water.
