Abstract

To study the relationship between pathogenic differentiation and toxin-producing capability，thirteen strains and their culture filtrates of Botryosphaeria dothidea （Moug. ex Fr.） Ces. ＆ de Not. from different regions and hosts were inoculated to the 30 cm long cutting of Populus × beijingensis，and we analyzed the pathogenic differentiations and toxin-producing capabilities，as well as their correlation using the degree of pathogenicity and toxicity on 30 cm long cutting of Populus × beijingensis as the appraisal index. Results showed that there were very significant differences （P＜0.01） in pathogenicity and their toxin-producing capability among these isolates. According to the disease and toxicity index，the 13 isolates were correspondently divided into 3 groups of strong，medium，and weak pathogenicity and toxicity by cluster analysis. There was obvious positive correlation （r = 0.854，P＜0.001） between pathogenicity and toxin-producing capability. ［Ch，7 fig. 3 tab. 13 ref.］
