摘要
西瓜营养丰富、甘味多汁、清爽解渴,堪称＂夏季水果之王＂。我国西瓜生产面积和产量均居世界第一,西瓜已成为我国重要的经济作物之一。近年来,由于连作重茬,导致西瓜病害日益加重,严重制约西瓜产业的发展[1]。
In September of 2009,watermelons stored in low temperature conditions for 7 days were rotted and caused above 90% losses in Kaifeng.The fungus was isolated from diseased tissues and the morphological characteristics,pathogenicity and DNA sequence of 5.8S rDNA-ITS were studied.The fungus was identified as Colletotrichum orbiculare based on the morphological characteristics.DNA sequence of 5.8S rDNA-ITS of the isolate was 100% homologous with the other 5.8S rDNA-ITS sequences of C.orbiculare in GenBank.Inoculated watermelon with this isolate could produce the same symptoms as naturally infected plants.Reisolation of the fungus from lesions on inoculated fruit confirmed that the causal agent was C.orbiculare which caused watermelon rot during the storage period.
