摘    要:为进行耐荫蕨类筛选,通过收集文献数据,选择比叶面积、比叶重、叶绿素含量、最大光合速率、光补偿点和光饱和点6个指标,计算各指标的表型可塑性指数(PPI)和耐荫临界值(STT).结果表明:蕨类植物的PPI变化范围为0.74~0.96,各指标的STT值分别为叶绿素质量分数1.9 mg.g-1、叶绿素a/b值2.3、比叶重36 g.cm-2、最大光合速率5.5 μmol,m-2.s-1、光补偿点24 μmol.m-2.s-1、光饱和点460μmol.m-2.s-1.利用STT值可以进行多途径的耐荫蕨类评价和筛选.

关 键 词:叶绿素含量  光合参数  表型可塑性指数  耐荫临界值  蕨类

Abstract:For the purpose of shade-tolerant fern screening,six indicators were chosen,which were specific leaf area,leaf mass per area,chlorophyll contents,maximum photosynthetic rate,light compensation point,and light saturation point,then the phenotypic plasticity index(PPI) and shade-tolerant threshold(STT) for the six indicators were calculated based on collected literature data.The results showed that the PPI of ferns varied within a range of 0.74-0.96.The STT values of each index were as follows: chlorophyll co...
