Leaf morphological characters of 22 compositae herbaceous species in Horqin sandy land

Abstract

Abstract: The study on the leaf traits of 22 compositae herbaceous species in Horqin sandy land indicated that there was a positive correlation between leaf volume and leaf thickness(r=0.782),while the correlations between leaf thickness and leaf tissue density,specific leaf area and leaf tissue density,and leaf volume and leaf tissue density were negative,with r values being-0.767,-0.559 and-0.505,respectively.No significant correlations were observed among other leaf traits.Based on the categorical or binary data,these 22 species were divided into 3 groups by cluster analysis.One-way ANOVA analysis suggested that there was a markedly significant difference among the groups in their leaf thickness,volume,weight ratio,and tissue density.
