植物的耐阴性评价

Assessment of Plant Shade Tolerance

对近年来与植物耐阴性有关的部分研究工作进行了整理,综述了科研工作者们在评价植物耐阴性时常用的几种方法。国内的工作主要采用的评价依据是植物的形态特征和生理特征。常用的形态特征如比叶面积,常用的生理指标如光补偿点、光饱和点、最大光合速率、叶绿素含量等。经常用到的方法有统计学指标,如生长速率和死亡率;以及环境指标,即植物在自然界所偏好的生存环境的光照条件。

This article summarized the research about plant shade tolerance assessment published in recent years to give a comparison on different shade tolerance assessment methods.Shade tolerance are mainly assessed by their morphological characteristics like specific leaf area,demographic traits like growth rate and mortality rate,physiological traits like light compensation point,light saturation point,photosynthetic rate and chlorophyll content,and habitat preference,i.e.where were the species tend to be found in natural f orests.It compared advantages and shortages of these methods and provided suggestions for shade tolerance assessment.
