我国北方百里香功能性状与环境的适应性研究
Study on the Adaptation of Functional Traits of Thymus mongolicus to the Environment in Northern China
摘要
Abstract
This study examined 59 wild samples of Thymus mongolicus collected from Inner Mongolia Autonomous Region and Shanxi Province in China.By assessing eight functional traits of the stems and leaves,and employing descriptive statistics,correlation analysis,principal component analysis(PCA),and cluster analysis,we investigated the variations in functional traits among different regions and their rela-tionship with environmental factors.The aim was to provide scientific basis and reference for the protection and utilization of T.mongolicus.The results revealed a high degree of overall variation in the functional traits of T.mongolicus,with coefficient of variation ranging from 19.02%to 63.67%.Notably,stem node length exhibited the highest coefficient of variation,whereas leaf length showed the lowest.Signifi-cant correlations observed between functional traits and environmental factors,specifically,stem length was positively correlated with altitude,and leaf width was negatively correlated with latitude.Further-more,multiple functional traits were significantly correlated with each other,with stem node number posi-tively correlated with leaf number and negatively correlated with stem node length.The eight functional traits could be grouped into three principal components,accounting for 82.01%of the total variance.Based on these functional traits,latitude,and longitude,cluster analysis classified the 59 samples into three distinct groups.关键词
