摘　　要：通过不同培养条件对诱抗菌桃褐腐病菌生长和产孢试验研究 ,明确了该菌最适生长温度范围为 19～2 7℃ ,最佳产孢温度范围为 17～ 2 3℃ ;不同光照条件对桃褐腐病菌生长影响不大 ,但对产孢影响较大 ,12h/12h光暗交替处理可明显提高产孢量 ;病菌对酸碱度适应性很强 ,生长和产孢的最适pH值为 5 .5～ 6 .0。The growth and sporulation of Minilinia Laxa, the pathogen of induced resistance under different culture condition were studied, which revealed that the pathogen optimum temperature for growth and sporulation were 19～27℃ and 17～23℃ respectively. The growth was not much affected by different lumination conditions, but the sporulation was greatly affected. The sporulation improved greatly with the treatment of sivitching 12h light to 12h darkness alternativly. The pathogen adapts to different pH conditions while the optimum pH is 5.5～6.0.
