【摘要】 探讨了白粉菌无性型特征,尤其是分生孢子形态、纤维体的显著与否、芽管形态及着生部位等形状在白粉菌分类中的作用.描述了 Arthrocladiella mougeotii(Lev.)Vassik.等6属7种白粉菌的无性型特征.结果表明,在缺乏有性型或完全采用有性型易与其它种混淆时,综合无性型特征进行白粉菌分类是完全可行的.更多还原

【Abstract】 The effect on the anamorph in the powdery mildews’ classification is studied in this article.Especially,the morphology of conidia,the fibrosi bodies,the type and position of germ tubes were explored and discussed,and the dignostic characteristics of the anamorph on Arthrocladiella mougeotii,Blumeria graminis,Erysiphe cichoracearum,E.galeopsidis, Oidium sp.,Podosphaera leucotricha and Sphaerotheca fuliginea are described in details. The results indicated that the powdery mildews can be identified with a combination of sever- al characteristics of the anamorph,especially when the telemorphs are infrequently observed or easily confused.更多还原
