【摘要】 为了评估漂浮育苗剪叶传播烟草从顶病的风险,以剪刀剪病叶后再剪苗和剪刀蘸取病烟汁液后再剪苗2种剪叶方法研究了漂浮育苗剪叶对烟草丛顶病和烟草普通花叶病的传播效果。调查数据显示,2种剪叶方法均不能传播烟草丛顶病,但能传播烟草普通花叶病,其平均发病率分别为36.67%和63.33%。实验结果表明,漂浮育苗剪叶不易传播烟草丛顶病,但易于传播烟草普通花叶病。更多还原

【Abstract】 To evaluate the risk of clipping-leaves to transmiting tobacco bushy top disease in floating system,tobacco seedling were clipped using scissors clipped the leaves with tobacco bushy top virus(TBTV) and tobacco mosaic virus(TMV)and dipped the two virus solution,respectively.The incidence of TBTV and TMV were investigated after 28 days,the data indicated that the two clipping treatment methods in floating system can not transmitted TBTV,but the average incidence of TMV were 36.67% and 63.33%,respectively.The results suggested that clipping treatment in floating system is not easy to transmit TBTV,but is easy to transmit TMV.更多还原
