摘要
笔者于2022年4月在广西南亚热带农业科学研究所澳洲坚果种质资源圃内发现澳洲坚果干花病,该病害危害花序,造成花瓣变褐、花序轴干枯甚至整个花序干枯死亡。本研究根据柯赫氏法则鉴定病原菌,并依据其形态学特征及TEF-TUB-ITS多基因联合建树明确病原种类,结果显示其致病菌为亚洲新拟盘多毛孢Neopestalotiopsis asiatica与腐生新拟盘多毛孢N.saprophytica。这是亚洲新拟盘多毛孢与腐生新拟盘多毛孢造成澳洲坚果干花病的首次报道。
In Macadamia integrifolia germplasm resource nursery of Guangxi South Subtropical Agricultural Science Research Institute,the dry flower disease of macadamia was found.By Koch’s postulates,morphological characterization and multi-sequence phylogenetic analyses of TEF-TUB-ITS,the pathogens were identified as Neopestalotiopsis asiatica and N.saprophytica.This is the first report on N.asiatica and N.saprophytica causing macadamia dry flower disease in China as well as in the world.
