Biomass of Rhodiola fastigiata

    Corresponding author: ZHENG Wei-lie

Abstract: Rhodiola fastigiata is a famous,rare medicinal plant found in China. In order to rational utilization of this plant,its biomass was analyzed in four different habitats of Sejila Mountain in Tibet(Xizang) using correlation analysis. Results showed that environmental conditions affected average moisture content with scape and leaf > belowground(root) > main and branch stems,but not the ratio of the average modular moisture content to the average moisture content. The ratio of the fresh weight of aboveground to belowground parts was 6.65;the dry weight ratio was 7.57;the average individual biomass was 5.721 3 g;and the resource capacity was 93.8 kg·hm-2. Biomass of main and branch stems,aboveground parts,and the individual plant showed similarities(P<0.01) to stem rings,which correlation curves was“S”shaped;these were fit to a logistics equation;their environmental capacities were 12.749 7,13.226 9 and 15.534 5,and their corresponding instantaneous growth rates were 0.277 9,0.338 6 and 0.316 9,respectively. Stem and leaf biomass as well as belowground parts had a significant (P<0.01) correlation with a polynomial,which were fit to a logistics equation. Also,basic diameter to biomass of various parts were fit to a power function with correlation coefficients of r =0.802 1 for the main and branch stems,r = 0.803 2 for the aboveground parts,and r = 0.812 9 for the individual plant.
