【摘要】 对引起大蒲葵叶斑病的拟盘多毛孢(Pestalotiopsis neglecta)进行了生物学特性和形态学研究,结果表明该菌在10～30℃范围内均可生长,最适生长温度为25℃;该菌适宜在偏酸性基质中生长,最适pH值为5;供试碳源对菌丝生长的影响不显著,供试氮源中磷酸二氢铵较有利于菌丝生长。更多还原

【Abstract】 The biological characteristics and morphology of Pestalotiopsis neglecta,which could lead to leaf spot of Livistona saribus,were studied.The results showed that this pathogen could grow at the temperature from 10 ℃ to 30 ℃,and the optimum temperature for the growth was 25 ℃.It was suitable for Pestalotiopsis neglecta to grow in the nearly-acid substrate,and the optimum pH-value was 5.The tested carbon source had no significant influence on the hyphal growth,and among the tested nitrogen sources,ammonium dihydrogen phosphate was beneficial to the hyphal growth.更多还原
