| 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. |
