摘      要：Seventeen morphological and anatomical characteristics of the leaves were selected from five natural populations to explore the variation in leaf traits of Lits ea core ana *** and the effects of geographical environment on these *** analysis of variance,multiple comparisons,principal component analysis(PCA),and correlation analysis were conducted to explore the variations within and between populations and their correlation with geographical and climatic *** differences in the 17 leaf traits were observed within and among *** average,the relative contribution of within population variation to total variation was 24.8%,which was lower than among population variation(54.6%).The average differentiation coefficient of the traits was 65.8%,and the average coefficient of variation 11.8%,ranging from6.7%for main vein thickness to 21.4%for petiole *** PC A results showed that morphological characteristics were divided into two categories,and the level of variation was greater than that of leaf *** of the leaf traits were significantly correlated with geography and climate and showed a gradual variation with longitude,latitude,and *** areas with high temperatures,less rainfall,and strong seasonal rainfall,the leaves are larger,longer and *** study shows that variations in leaf traits of *** *** mainly come from variations among *** level of trait differentiation among populations is high and the level of variation within populations *** findings help further understand leaf morphological characteristics of this species and can provide a valuable reference for the protection and sustainable utilization of this natural resource.
