摘要
通过拮抗实验,研究了59个野菊内生真菌菌株对油茶炭疽病及油茶稍枯病病原菌的拮抗性.结果表明:89.8%供试真菌菌株对油茶病原菌孢子萌发或菌丝生长有抑制作用.拮抗菌株在代谢过程中能产生抑制病原菌生长发育的抑菌物质,这些物质存在于菌丝内或分泌于菌丝外.筛选得到2个油茶病原菌强拮抗菌株,大茎点霉菌Y11和Y29.
Through antagonistic test,the antagonistic characteristics of 59 endophytic fungus strains from Chrysanthemum indicum to two species of pathogens on Camellia oleifera were studied.The results showed that 89.8% strains of the endophytic fungi tested can inhibit the spore bourgeon and hypha growth of the pathogen on Camellia oleifera.The antagonistic fungus strains could produce some substances,existed in hypha cells or excreted out of mycelium,to restrain fungi.Two strains of endophytic fungi,Y11 and Y29,having strong antagonistic characteristic were gained by selection.
