摘要
从加拿大进境油菜籽中随机选取船载油菜籽、筒仓油菜籽、菜籽粕和下脚料4类加工过程的样品调查油菜茎基溃疡病菌的发生情况。结果表明,18份船载油菜籽、7份筒仓油菜籽和11份下脚料样品的油菜茎基溃疡病菌PCR检测都呈阳性,而8份菜籽粕样品全为阴性。3份阳性样品的病原菌分离、鉴定与致病性测试结果证实了PCR的检测结果。
In this research,four types of samples,including shipborne rapeseed,storage silo rapeseed、rapeseed dregs and byproduct,were randomly selected from processed rapeseeds to investigate the ocurrence of Leptosphaeria maculans.The results showed that all eighteen shipborne rapeseeds,seven storage silo rapeseeds,and eleven byproducts were positive in PCR detection of Leptosphaeria maculans,but eight rapeseed dregs were negative in such detection.The results from pathogen isolation,charcterization and pathogenicity testing of three samples comfirmed the PCR detection.
