摘要

对2004年以来甘肃省百合科、苋科、木犀科、大戟科、桔梗科药用植物链格孢属引起的病害进行了鉴定,结果如下:芍药叶斑病病原为细链格孢[Alternaria alternata (Fr.:Fr.)Keissler],青葙叶斑病病原为青葙链格孢[A.ce-losiae (Tassi)O.Sǎvul],连翘灰斑病病原为A.forsythiae Harter,引起连翘灰斑病、甘遂褐斑病病原为甘遂链格孢(A.kansuiae T.Y.Zhang&.Z.Zhang),沙参黑斑病的病原为茄链格孢[A.solani(Ellis et Martin)Sorauer].%Field survey and identification of Alternaria on Liliaceae,Amaranthaceae,Oleaceae,Euphorbiaceae and Campanulaceae were conducted in Gansu Province from 2004.The results revealed that the pathogen of Paeonia lactiflora leaf spot was A.alternata (Fr.:Fr.)Keissler; the pathogen of Celosia argentea leaf spot was A.celosiae (Tassi) O.Sǎvul.; the pathogen of Forsythia suspensa grey spot was A.forsythiae ; the pathogen of Euphorbia kansui brown spot was A.kansuiae T.Y.Zhang & J.Z.Zhang,and the pathogen of Adenophora stricta black spot was A.solani (Ellis et Martin)Sorauer.
