摘　　要：培养基的ｐＨ值能影响李瑟组镰刀菌的生长速度、菌落形态、色泽、产孢量及大孢子形状等。ｐＨ３－４菌落偏向红色，ｐＨ６－７菌落为紫色，ｐＨ１０则有些菌株变为淡蓝色、灰色。但菌株能改变基物的ｐＨ值。李瑟组镰刀菌的６个菌株最适生长发育的ｐＨ值为６－７。The growth rate,colony morphology and color,sporulation and macroconidial shape were influenced by the cuIture medium pH. At pH 3-4,6-7,and 10 in the mediunm,the colony color was redish,purple,and paleblue or grey,respectively. The fungul growth may n1odify the substrate pH value.The optimum pH value for tested six strains of Section Liseloa of Fusarium was 60-7.
