泡桐丛枝病和枣疯病病害症状相似,病原皆为MLO。传播媒介前者是茶翅蝽和虻蝽,后者为中拟菱蚊叶蝉(简称枣叶蝉)。1981年6月,将40多头饲枣疯病病毒7天的枣叶蝉成虫,接于锦纶纱笼内的5株泡桐实生苗上,8月中旬成虫全部死亡。1982年8月上旬,有一株苗木呈现典型的丛枝病症状,3个月后逐渐枯死。1983年初,又有一株苗木表现丛枝症状。1982年9月初、10底分别将枣叶蝉传毒发病的泡桐苗上的小叶柄、叶脉进行固定包埋,做超簿切片进行电镜观察。发现叶脉
Paulownia witches broom disease and jujube disease similar symptoms, pathogens are MLO. The former is a tea-leaf bugs and stink bugs, the latter for the mosquito leafhopper (referred to as jujube leafhopper). In June 1981, more than 40 adult juvenile datehoppers feeding juvenile goat bovine viruses were placed on 5 juvenile Paulownia saplings in nylon sarongs, and all adults died in mid August. In early August 1982, a seedling showed symptoms of typical cuckoo and gradually died after 3 months. In early 1983, another seedling showed the symptoms of twig. At the beginning of September 1982, at the end of 10, the petiole and veins on the Paulownia seedlings, which were the main pathogens of the leafhopper, were immobilized and embedded. Veins found
