摘　　要：本研究采用组织分离法从鸡蛋花(Plumeria rubra Linn.cv.Acutifolia)叶片中分离出一株病原真菌菌株,命名为JD3,并对菌落形态特征和ITS序列分析。结果显示,鉴定JD3菌株为胶孢炭疽菌(Colletotrichum gloeosporioides),该菌株能够利用多种碳源和氮源,其中D-甘露糖醇为最佳碳源,酸水解酪蛋白为最佳氮源。本研究结果可为诊断和防治鸡蛋花炭疽病提供参考。In this study,a pathogenic fungal strain,named JD3,was isolated from the leaves of Flos Plumeriae(Plumeria rubra Linn.cv.Acutifolia)by tissue isolation method,and analyzed for colony morphological characteristics and ITS sequence.The results showed that strain JD3 was identified as Colletotrichum gloeosporioides,and the strain was able to utilize a variety of carbon and nitrogen sources,among which D-mannitol was the best carbon source and acid-hydrolyzed casein was the best nitrogen source.The results of this study can provide reference for the diagnosis and control of anthracnose of Flos Plumeriae.
