摘要
云南山茶(Camellia reticulata Lindl.)为世界著名观赏花木,在云南栽培历史悠久,其花大繁茂、花姿多样、花色绚丽,在冬春季节构成了云南高原的独特景观,为“云南八大名花”之首,是昆明市的市花,观赏价值极高[1-3]。滇山茶常见的病害有枝枯病、花腐病、炭疽病、花叶病、媒污病等[4-5],生产和培育者只是从发病症状来判断病因,从而进行病害防治工作,但却不能精确、高效地完成防治工作。
In 2021,typical branches of Camellia reticulata dieback disease were collected from Zixi mountain,Chuxiong City,Yunnan Province,and one strain was obtained by tissue isolation and single-spore culturing method.Based on pathogenicity determination,morphological characteristics and phylogenetic analysis of ITS,GAPDH,CAL,ACT,CHS-1 and TUB gene sequences,the pathogen was identified as Colletotrichum camelliae.This is the first report that Colletotrichum camelliae caused Camellia reticulata dieback disease in China.
