Characteristics of Biomass Allocation and Allometric Growth Analysis of Draba Nemorosa L.in Different Habitats
In order to understand the characteristics of biomass allocation and its allometric growth rela-tionship,the differences in biomass allocation,phenotypic plasticity and the ratio of reproductive and nutrient components were investigated and analyzed in different habitats,and the allometric growth rela-tionship between plant organs was analyzed by standardized spindle regression,and the distribution law and adaptation strategies of Draba nemorosa L.were revealed in different habitats.The results showed that there were significant differences in the biomass and distribution pattern of Draba nemorosa L.in different habitats,and the biomass allocation of each organ was in the aboveground part>the underground part,the inflorescence biomass allocation ratio was the largest,the root part was the smallest,the phenotypic plasticity of basal leaves was the highest.There were significant differences in the allometric growth rela-tionship between aboveground,underground and inflorescence biomass under different habitats,The overall biomass allocation rate of Draba nemorosa L.showed that the inflorescence biomass>aboveground biomass>underground biomass,and the allometric growth relationship was not unique in different habi-tats,reflecting the growth and adaptation strategies of Draba nemorosa L..
