海滨雀稗弯孢霉叶斑病病原鉴定及生物学特性研究

摘要

弯孢霉叶斑病是高尔夫草坪养护管理中的一种重要病害 ,为明确该病害的致病病原及相关特性 ,对海滨雀稗弯孢霉叶斑病的病原进行了种类鉴定、致病性测定和生物学特性研究.结果表明 :海滨雀稗弯孢叶斑病致病菌为新月弯孢霉[Curvularia lunata(Wakker) Boedijn];该菌菌丝生长最适温度为30℃ ,pH为7 ,不同光照对菌丝生长无明显影响 ,以麦芽糖为碳源、蛋白胨为氮源比较适合菌丝的生长.%The Curvularia leaf spot is one of the important diseases in golf courses maintenance management .In order to effectively clear the basic characteristics of the disease pathogen ,species identification ,the pathogenic determination and the biological characteristics of the Curvularia leaf spot on Paspalum vaginatum were re-searched .The results showed that the Curvularia leaf spot on Paspalum vaginatum pathogens belonged to Curvularialunata (Wakker)Boedijn .Pathogenic bacteria of which the mycelium's optimum temperature for growth was 30℃ and pH was 7 .Different illumination had no effect on the growth of the mycelium .Using maltose as the carbon source and peptone as the nitrogen source were more suitable for the growth of the myce-lium .
