Abstract

In this study，11 indexes closely related to the growth potential and ornamental value of 20 Guoqing chrysanthemums with small inflorescences in their growth stage were measured and their drought resistance was evaluated by an analysis of variance，a principal components analysis，and a subordinate function analysis. Results of the principal components analysis showed the indexes could be classified into 3 component parts with 7 indexes closely related to drought-resistance; namely，stress indexes of root-shoot ratio，underground biomass，number of branches after topping，flowering phase of population，flowering quantity，flower diameter，and the number of ligulate flowers. Using the average of subordinate function，drought resistance was also divided into three classes.［Ch，1 fig. 5 tab. 20 ref.］
