| 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].瓜类炭疽菌Colletotrichum orbiculare( Berk.&Mont.)Arx]引起的西瓜腐烂病几乎在世界各瓜区均有发生,一旦发病就会造成严重的损失2].以往对炭疽病病原的分类、鉴定,主要是基于形态学特性、致病性测定的传统方法.

| Abstract: | 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.Inocul... |
