不同浓度臭氧水对致病疫霉菌Phytophthora infestans孢子萌发抑制作用初报
臭氧水 致病疫霉菌 Phytophthora infestans (Mont.) de Bray 孢子萌发
2009/11/30
本文采用不同浓度臭氧水对致病疫霉菌Phytophthora infestans (Mont.) de Bary孢子囊萌发进行了试验，结果表明：臭氧水处理对孢子囊萌发的影响与臭氧水浓度密切相关，以9 mg/Kg臭氧水处理1 min可以抑制95%以上孢子囊萌发，以18 mg/Kg臭氧水处理1 min则100%抑制孢子囊萌发。无论在高浓度还是在低浓度条件下，处理时间1分钟或2分钟对孢子囊萌发没有产生显著...
