摘  要:
为调查广西地区红锥(Castanopsis hystrix)叶部真菌性病害的种类,本研究从广西南宁市良凤江森林公园、博白林科所、博白林场和高峰林场4个地区采集红锥叶部病害样本,使用常规组织块分离法获取其致病菌,结合形态学观察和r DNA-ITS序列分析进行病害鉴定。结果表明:红锥叶部发生的主要病害有4种,分别为赤斑病(Pilidella granati)、褐斑病(Pestalotiopsis pauciseta)、炭疽病(Colletotrichum gloeosporioides)、藻斑病(Cephaleuros virescens Kunze);其中,前3种病害为在红锥上新发生的病害。

摘  要:
For investigating the species of fungal pathogen of leaf diseases on Castanopsis hystrix,the diseased samples of C. hystrix were collected from seedling garden in Nanning Liangfengjiang National Forest Park of Guangxi Province,the research institution of forestry in Bobai County,the center of forestry in Bobai County,the center of forestry in Gaofeng. By means of combining morphological characteristics with molecular biological techniques,there were four species of leaf diseases on C. hystrix,which were red spot( Pilidella granati),brown spot( Pestalotiopsis pauciseta),anthracnose( Colletotrichum gloeosporioides),algal spot( Cephaleuros virescens Kunze). Among them,the former three diseases are new diseases on C. hystrix.
