摘要
山竹作为重要的特色热带水果,近年在海南种植面积不断扩大。但山竹病害频繁发生,严重制约着其产业的健康发展。作者于2018年5月至2019年9月对海南省保亭县山竹病害进行了调查,发现叶斑病和枝条溃疡病对山竹危害较为严重。为了明确病害的病源,本研究通过形态学观察、ITS序列分析结果以及科赫法则验证致病性测定,将病原菌分别鉴定为胶孢炭疽菌(Colletotrichum gloeosporioides)和小孢拟盘多毛孢(Pestalotiopsis microspora)。该研究结果可为山竹病害诊断和防治提供科学依据。
As mangosteen is such a significant unique tropical fruit,its planting scale has been increasing in Hainan in recent years.While disease occurs to mangosteen frequently which have severely restricted the healthy growth of the industry.In this study a survey of mangosteen diseases had been conducted in Baoting county in Hainan Province from May 2018 to September 2019,through which it was found out that mangosteen was seriously affected by leaf spot disease and branch canker.In order to clarify the pathogen of these two diseases,the author had verified the pathogenicity identification through morphological observation,ITS sequence analysis results and Koch's postulates,and identified the pathogens of leaf spot and branch canker to be Colletotrichum gloeosporioides and Pestalotiopsis microspora respectively.The results of this study can provide a scientific basis for diagnosis and prevention of mangosteen diseases.
