摘　　要：对海南5个菠萝产区菠萝叶部真菌病害进行了调查研究。结果表明,共有6种真菌病害发生较普遍,危害较重,分别由胶孢炭疽菌Colletotrichum gloeosporioides、画眉草弯孢菌Curvularia eragrostidis、刺环裂壳孢菌Annellolacinia dinemasporioides、掌状拟盘多毛孢菌Pestalotiopsis palmarum、喙状凸脐蠕孢菌Exserohilum rostratum和金色毛壳菌Chaetomium aureum引起,其中喙状凸脐蠕孢菌E.rostratum和金色毛壳菌C.aureum为我国首次报道。本文同时对6种病害的发病症状和病原形态进行了初步描述。The fungal diseases on pineapple（Ananas comosus（L.） Merr.） leaf were primarily investigated in 5 producing regions of Hainan.The result showed that 6 kinds of fungal leaf diseases,caused by Colletotrichum gloeosporioides,Curvularia eragrostidis,Annellolacinia dinemasporioides,Pestalotiopsis palmarum,Exserohilum rostratum and Chaetomium aureum,respectively,were found to widely occur and had severe harm here,and the E.rostratum and C.aureum were firstly reported on pineapple in China.Besides,the symptoms and pathogen morphology of 6 kinds of fungal leaf diseases were primarily described.
