枣疯病病原的鉴定及致病机理研究

摘 要：枣疯病在我国普遍发生，会造成枣园（枣树）减产甚至绝产，严重威胁我国枣产业的健康发展。本文从形态学及分子生物学认知分类、活体培养保藏、检测鉴定、致病机理共4个维度，系统地总结了1947年以来国内对枣疯病病原的研究，以期为今后枣抗病品种的培育、特效专效农药及绿色防控新技术的研发提供参考。

Abstract： Jujube witches’ broom （JWB） is a widespread disease in China， leading to reduced or even complete loss of yield in jujube orchards， posing a severe threat to the healthy development of the jujube industry in China. This paper systematically summarized and evaluated the research on the pathogen JWB in China since 1947 from four aspects： morphological and molecular biological identification， live culture preservation， detection and identification， and pathogenic， to provide a reference for the future development of disease-resistant varieties， specific and effective pesticides， and new technologies for green control.

Keywords： Jujube witches’ broom; phytoplasma; identification and classification; living preservation; pathogenic mechanism
