中文摘要：

Large sample sampling was adopted in this paper for the statistical analysis of leaves of four populations of Vetiveria zizanioides( introduced,local wild,domesticated wild populations of different years). The results showed that four populations varied in different degrees in terms of tiller height,leaf biomass,and leaf biomass ratio. Leaf length,leaf width,and ratio of leaf width to length of different populations also varied,but had similar power-function change regularity,and showed converging leaf biomass growth pattern and leaf growth process.
