摘要
通过田间调查发现,铜陵白姜姜瘟病在铜陵当地表现出木质部黄心和黑心2种症状,通过TTC平板分离、致病性测定、16SrDNA以及青枯菌特异性鞭毛基因(fliC)检测表明,导致2种不同姜瘟病症状的病原菌均为青枯雷尔氏菌(Ralstonia solanacearum),但二者致病性存在明显差异。
Field investigation revealed that plants infected with ginger bacterial wilt of white ginger showed two different symptoms, yellow-heart and black-heart in the xylem. Through the experiments of TTC plate separation, pathogenicity determination, sequencing of 16S rDNA and flagellum gene （fliC）, we found that both the two different symptoms were caused by Rlastonia solanacearum, but their pathogenicity had significant difference.
