摘　　要：为了探明影响桃褐腐病发生和发展的因素，研究了温度、pH值、光照、营养条件等对桃褐腐病菌的生长和分生孢子萌发的影响。结果显示：桃褐腐病菌营养生长最适温度范围为20～25℃；最适pH值范围为6～7；光暗交替有利于该菌生长；供试的7种培养基中，PDA＋KNO3对生长最有利。分生孢子萌发的最适温度为25℃，最适pH值为8，最适营养液为1％蛋白胨液。The effect of temperature, pH, illumination and nutrition on mycelial growth and conidial germination of Monilinia fructicola was studied. For the fungal growth, the optimum temperature was 20-25 ℃, the optimum pH was 6-7 and the optimum illumination was 12 h light alternated with 12h dark. For conidial germination, the optimum temperature was 25 ℃, the optimum pH was 8, and the optimum nutrition was 1% peptone.
