Study of Response Curve about Fraxinus griffithii on Karst Hills in Guilin
摘要
Abstract
[Objective] The research aimed to discover the physioecology of Fraxinus griffithii. [Method] The response curve of Fs griffithii in Fraxinus griffithii community was measured using LI-6400 photosynthesis system (LI-COR. USA). [Result] In August the light saturation point of F. griffithii was high and light compensation point was low, which was favorable of F. griffithii adapting to the environment in karst hills. In November, the light saturation point decreased while the light compensation point increased. In August carboxylase efficiency of F. griffithii was 0.04, and that in November was lower, which was only 0.01. [Conclusion] F. griffithii had some adaptation mechanism to low light environment and it had strong utilization availability of weak light关键词
