中文摘要: |
近5年来, 湖南麻阳苗族自治县的柑橘种植园发生柑橘炭疽病。采集发病柑橘植株, 分离其病原菌, 从病原菌的培养性状和形态学特征、内转录区(ITS)序列分析和系统发育关系比较等方面对该病原菌进行了鉴定, 并探索了枯草芽胞杆菌(Bacillus subtilis)CGMCC 1.354对其的抑制作用。结果表明:该地区柑橘炭疽病菌为盘长孢状刺盘孢(Colletotrichum gloeosporioides)。枯草芽胞杆菌CGMCC 1.354对该病原菌具有较强的抑制作用, 其分泌的抑菌物质能抑制柑橘炭疽病菌菌丝生长和孢子萌发。 |
英文摘要: |
Anthracnose on citrus has occurred in Mayang Miao Autonomous County, Hunan Province in the recent five years. The pathogen causing citrus anthracnose was isolated from citrus orchards of Mayang Miao Autonomous County. Based on cultural and morphological characteristics, ribosomal DNA (rDNA) internal transcribed spacer (ITS) sequence analysis and phylogenetic relationships with other species of Colletotrichum, the pathogen was identified as Colletotrichum gloeosporioides. Bacillus subtilis CGMCC 1.354 showed strong antagonistic activity against the pathogen, and the antifungal substance produced by B. subtilis CGMCC 1.354 strongly inhibited the hyphal growth and spore germination of C. gloeosporioides. |
