Abstract

The correlations of the dry weight of genet and the number and the dry weight of stolon,the dry weight of ramet,as well as the ratios of dry weight of stolon and ramet/dry weight of genet of L.brachystachya have been analyzed based on the samples collected from 5 plots at different altitudes on the Qinghai-Xizang Plateau.The results show that except the habitats affected by human activities,there was a significant linear correlation between dry weight of genet and the number of stolon,the dry weight of stolon per cm(P<0.01).However,the dry weight of genet does not affect the dry weight of ramet directly.The ratios of the dry weight of stolon and ramet/the dry weight of genet in plot 1(the highest altitude) and 5(the lowest altitude) are the highest.Dry weight of L.brachystachya has an significant effect on its clonal growth,this effect varys with altitude.

Key words： L.brachystachya The dry weight of genet Clonal growth Qinghai-Xizang Plateau
