科尔沁沙地菊科植物叶性状系统发育信号研究
|
摘要
科尔沁沙地植物叶性状的研究可揭示叶性状受环境驱动及其响应,但当前研究未充分考虑物种进化对叶性状的影响.以科尔沁沙地22种菊科植物为对象,研究比叶面积、叶片体积、叶重比、叶片组织密度、叶片干物质含量等叶片性状的系统发育信号.研究发现比叶面积、叶体积、叶重比、叶组织密度、叶厚度、叶干物质含量的K值(表征系统发育信号)分别为0.727,1.02,0.687,0.881,0.992,0.866.各叶性状系统发育信号均不显著(P>0.05).据此认为,科尔沁沙地菊科植物叶性状特征与系统发育关系不大.该研究可为深入理解环境因素与植物进化的相互作用提供参考,为当地植被恢复提供科学依据.
The studies of plant leaf traits in the Horqin Sandy Land reveal that the leaf traits are regulated by environmental factors and their response to environment.However,the effects of evolution on leaf traits are not fully considered.In this study,we studied the phylogenic signal of leaf traits,i.e.leaf area,leaf volume,leaf weight ratio,leaf tissue density,leaf dry matter content,in 22 species of Compositae in the Horqin Sandy Land.The results showed that the K value(phylogenetic signal) of leaf area,leaf volume,leaf weight ratio,leaf tissue density,leaf thickness and leaf dry matter content were 0.727,1.02,0.687,0.881,0.992,0.866,respectively.The phylogenetic signals of the above traits were not significant(P> 0.05).It is suggested that the leaf traits of Compositae in the Horqin Sandy Land are little influenced by phylogenetic evolution.This study might helpful for understanding the interaction between environmental factors and plant evolution and for promoting vegetation restoration in the Horqin Sandy Land.
