【目的】探讨中国油茶苗圃炭疽病原菌种类,揭示油茶苗圃炭疽病菌抗药性,为其防治提供依据和指导。 【方法】分离油茶苗圃炭疽病菌,并对分离菌株的ApMat基因进行PCR扩增和测序,通过对序列系统发育分析鉴定炭疽病原菌种类;采用区分剂量法测定所有菌株对杀菌剂多菌灵、乙霉威、戊唑醇和咪鲜胺的抗药性。【结果】湖南、江西、海南和广东4个省份分离的95株的油茶苗圃炭疽病病原菌主要是果生炭疽菌(Colletotrichum fructicola) 、暹罗炭疽菌(C. siamense) 、山茶炭疽菌(C. camelliae)和胶胞炭疽菌(C. gloeosporioides) 4个种,其中炭疽病菌分布范围最广、分离数量最多(83株,占总分离菌株的87.4%) 。抗药...

Objective: The objectives of this study were to identify the pathogens causing anthracnose of Camellia oleifera(oil-tea) in nursery in China and to reveal the resistance of anthracnose pathogens to fungicides, in order to provide targeted strategy for controlling oil-tea tree anthracnose. Method: The anthracnose pathogen was isolated from C. oleifera in nursery, and its ApMat gene was amplified and sequenced by PCR. The anthracnose pathogen species were identified by phylogenetic analysis. The resistance of all strains to fungicides carbendazim...
