摘要

为明确江西茶树叶部病害及其病原真菌发生情况,制定行之有效的绿色防控对策。2019—2022年对江西省61个茶园进行茶树叶部病害实地调查,采集病叶,对病原真菌进行分离纯化后分别进行形态学观察和基于内在转录间隔区（Internal transcribed spacer,ITS）序列的分子鉴定。研究发现,为害江西茶树的叶部病害有25种,初步分离获得258株茶树叶部病原真菌,分布在19个属。叶部病害病原真菌中以刺盘孢属（Colletotrichum）和类拟盘多毛孢菌（Pestalotiopsis-Like）分离率最高,是叶部病害的主要病原真菌。链格孢属（Alternaria）、葡萄座腔菌属（Botryosphaeria）、间座壳属（Diaporthe）、镰孢属（Fusarium）、黑孢属（Nigrospora）、拟茎点霉属（Phomopsis）和叶点霉属（Phyllosticta）7个属的真菌在多个茶园病叶中被分离到,为次要病原真菌。茶饼病和茶白星病在高海拔茶区流行,茶煤病在个别茶园为害较重。

Abstract

To clarify the occurrence of tea leaf diseases and their pathogenic fungi in Jiangxi Province, and to formulate effective green prevention and control measures. From 2019 to 2022, the field investigation of tea leaf diseases was carried out in 61 tea gardens in Jiangxi Province. The diseased leaves were collected, and after isolation and purification of the pathogens, morphological observation and molecular identification based on internal transcribed spacer (ITS) sequences were carried out respectively. It was found that there were 25 kinds of tea leaf diseases in Jiangxi Province, and 258 strains of pathogenic fungi were isolated from tea leaves, which were distributed in 19 genera. Among the pathogenic fungi of leaf diseases, Colletotrichum and Pestalotiopsis-like fungi had the highest isolation rate and were the main pathogens of leaf diseases. A total of 7 genera, including Alternaria, Botryosphaeria, Diaporthe, Fusarium, Nigrospora, Phomopsis and Phyllosticta were isolated from diseased leaves of several tea gardens and were identified as secondary pathogens. Tea blister blight and tea white scab are prevalent in high-altitude tea areas, and tea sooty mould is more serious in individual tea gardens.
