摘要: 室内试验表明,雪腐格氏霉(Gerlachianivalis)侵染小麦的适宜温度为17~20℃,20℃以上有利于病菌在寄主组织中扩展。相对湿度在93%以上2~3天,病害就会普遍发生,持续时间越长,发病越严重。在20℃及饱和湿度下,光强8000~10000lx,每天光照6h,最适于病菌侵入和扩展,长时间光照不利于病害发生。

关键词: 雪腐格氏霉, 侵染条件, 小麦

Abstract: The experiment results showed that the optimum temperature for Gerlachia nivalis penetration is 17~20℃,and for disease development in tissure of the host is above 20℃.The infection occured above RH 93% in 2~3 days,and the longer the period sustained,the severer the disease occured.Under 20℃ and saturated humidity condition,when light intensity is 8000 10000lx,and lihgt controlled 6h every day,it is suitable for infect and extensive.Long time sustained light is not suitable for disease occured.

Key words: Gerlachia nivalis, Infection condition, Wheat
