【摘要】 测定了从福建省得到的水葫芦致病菌——尾孢霉属菌株FJ24,在不同光照、温度、pH值、碳源、氮源和培养基等条件下菌丝的生长情况。结果表明,全黑暗条件有利于菌丝生长,温度为30℃、pH值为7.6时菌丝生长最快。最适培养基为MDYEA,最适碳源是可溶性淀粉,最适氮源为乙酸铵。更多还原

【Abstract】 Growth characteristic of fungus threads of water hyacinth pathogenic Cercospora sp.strain FJ24 collected from Fujian Province was studied under culture in vitro with various environmental factors including light,temperature,pH,carbon source,nitrogen source,medium and so on.The results show that the fungus threads grow best under condition of thorough darkness,and the fungus threads grow fast at 30 ℃ and pH 7.6.MDYEA,soluble starch and acetate ammonium might be the most suitable medium,carbon source and nitrogenous sources respectively.更多还原
