摘　　要：毛叶枣灰霉病菌是半知菌类葡萄孢属灰葡萄孢Botrytis cinerea Pers..病菌生长、产孢的最适培养基为马铃薯葡萄糖琼脂培养基(PDA);该菌的生长温度范围是5～28℃,产孢温度范围是5～20℃,最适于菌丝体生长、产孢和孢子萌发的温度分别为20℃、15℃和20℃;病菌在pH值3～9时均能生长和产孢,最适pH值为5～6,其孢子萌发的pH值范围是2～10,最适为5～6;在饱和湿度下孢子才可萌发;马铃薯葡萄糖液和枣叶汁可显著促进分生孢子萌发.＂The indian jujube grey mould was caused by Botrytis cinerea Pers.. The optimal medium of the pathogen for the mycelium growth and sporulation was PDA. The temperature for the mycelium growth and sporulation was 5 - 28℃ and 5 - 20℃ respectively, and the optimum temperature for mycelium growth, sporulation and conidia germination was 20℃, 15℃ and 20℃ respectively. The pH value for mycelium growth and sporulation ranged from 3 to 9 and the optimum pH ranged from 5-6. The pH value for the conidia germination was 2 -10 and the optimum pH was 5 -6. Saturated h indian jujube lea umidity was necessary for germination of the conidia. The potato dextrose liquor and liquor could promote conidia germination obviously.
