摘　　要：蛋黄果(Lucuma nervosa A. DC),为山榄科(Saptaceae)蛋黄果(Lucuma)属多年生常绿果树,于20世纪30年代引入中国,目前在广西、海南、云南等地均有种植[1]。蛋黄果果实营养物质丰富,果肉富含糖类、膳食纤维、微量元素,还含有多种微量元素[2],深受消费者喜爱。近年来,随着种植面积不断扩大,蛋黄果病害问题逐渐显现。Brown rot symptoms on fruit of Lucuma nervosa were observed in Guangxi South Subtropical Agricultural Science Research Institute.The samples were collected from the field,the pathogen was isolated by tissue isolation,and its pathogenicity was verified by the Koch′s rule.The pathogen was identified as Lasiodiplodia pseudotheobromae by combining morphological characteristics and ITS-TUB-RPB2-TEF1 sequence analysis.This is the first report of Lasiodiplodia pseudotheobromae causing brown rot on Lucuma nervosa fruit in the world.
