摘　　要：【目的】调查与诊断新疆哈密瓜主栽区甜瓜叶脉坏死病毒病,研究该病在甜瓜种植区的发生与分布状况,为鉴别与防治甜瓜叶脉坏死病毒病提供方法与依据。【方法】摩擦接菌法,对健康的哈密瓜植株进行侵染,用透射电子显微镜,分别观察大田采集感甜瓜叶脉坏死病毒病样品与人工侵染的哈密瓜植株叶片病原形态特征。【结果】摩擦接菌的哈密瓜植株发病症状与大田一致,通过镜检,确定新疆哈密瓜主栽区的病害是香甜瓜叶脉坏死病毒Melon vein necrosis virus(MVNV),病原是属于香石竹潜隐病毒属(Carmovirus)、属于线形病毒科(Flex iv iridae)。该病在新疆甜瓜主栽区均有发生,不同地区或者同一地区不同年份该病的消长变化有很大的差异。【结论】甜瓜叶脉坏死病毒病在新疆瓜区普遍发生,在部分地区已导致甜瓜生产绝收,该病的发生流行规律待进一步研究。【Objective】To investigate and analyze the occurrence and distribution of melon vein necrosis virus in the main melon planting area of in Xinjiang,and provide a method and basis for the identification and control of melon vein necrosis virus.【Method】Using mechanical inoculation method to perform inoculation on the healthy melon plants,and pathogen morphological characteristics of the leaves collected from infected MVNV melons in the field and artificially infected MVNV leaves of Hami melon were observed by transmission electron microscopy(TEM).【Result】The disease symptoms of artificially infected leaves were exactly the same with those in fields,and by transmission electron microscopy,it was confirmed that it belonged to the genus Carassius auratus(Carmovirus),which belongs to the family of linear virus(Flex iv iridae).Through investigation,it was made clear that the disease occurred in the main planting areas of Xinjiang melon,and the variation of the disease in different regions and different years in the same area was very different.【Conclusion】Melon vein necrosis virus generally occurs in melon growing area in Xinjiang,and in some areas it has led to the total production failure of muskmelon crops.The conclusion occurrence and epidemic regularity of this virus need to be further studied.
