隶属函数值法对5种岭南乡土植物耐阴性的综合评价

Comprehensive Evaluation on Shade-tolerant of 5 Indigenous Plant Species in Lingnan Region by Subordinate Function Values Analysis

采用隶属函数法对5种岭南乡土植物耐阴性进行综合评价,选取的耐阴性因子分别为MDA、SOD、可溶性糖、可溶性蛋白、叶绿素a/b、叶绿素含量。评价结果表明5种植物耐阴性的大小顺序是:小叶山龙眼>香叶树>黄果厚壳桂>红鳞蒲桃>黄牛奶树。

The shade tolerance of 5 indigenous plant species in Lingnan region was evaluated with the subordinate function values analysis.The contents of MDA,SOD,soluble sugar,solube protein and Chlorophyll and the ratio of Chlorophyll a：Chlorophyll b in each species were used as the indices for assessing their shade tolerant.The results show that the abilities of 5 indigenous plant species to tolerate shade were：Helicia cochinchinensis Lour.＞ Lindera communis Hemsl.＞ Cryptocarya concinna ＞ Syzygium hancei Merr.et Perry ＞ Symplocos laurina Wall.
