摘　　要：从广西大学芒果园的紫花芒和 4号芒的病果上分离出芒果蒂腐病菌Diplodinasp .,对其生物学特性研究结果表明 ,最适宜该菌生长的温度及pH分别为 2 5～ 2 8℃、5 .5。不同光照条件对菌丝生长、子座及分生孢子器的形成影响较大 ,其中以荧光最利于菌丝生长 ,而黑光最利于子座及分生孢子器的形成。该菌对丙环唑的敏感性大于其它测试药剂。Diplodina sp ,which caused stem end rot of mango,was isolated from two mango cultivars,Shihaomang and Zihuamang grown in the ochard of Guangxi University.The optimum temperature and pH for growth of the pathogen were 25～28℃ and 5.5,respectively.Florescent light was found to be more effective for the growth of mycelia and black light for the production of stroma.When lactose was used as carbon source and L-glutamic acid as nitrogen source,the fungus grown more faster than the other substance.The pathogen was more sensitive to propiconazole than the other fungicides tested.
