摘要: 为了研究溃疡病菌致病力分化与其产毒强弱间的关系，以来源于不同地区、不同寄主上的13个葡萄座腔菌Botryosphaeria dothidea菌株及其毒素原液（培养滤液）对北京杨Populus × beijingensis的 30 cm长枝条的致病程度及毒害程度为评价指标，对供试13个溃疡病菌菌株致病力分化、产毒强弱以及致病力分化与产毒强弱间的关系进行了研究。结果表明：供试13个溃疡病菌菌株致病力分化和其产毒强弱差异均极显著，达到0.01显著水平。聚类分析将13个菌株分成强、中、弱等3种不同的致病类群和强、中、弱等3种不同的产毒类群。不同溃疡病菌菌株产毒强弱与其致病力强弱有明显的正相关性，相关系数为0.854。图7表3参13

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.］
