摘要:
 对14个1年生杨树无性系(La、Pa、Ta、Qg、Ti、中林46、I-107、A23、A39、A46、A50、A54、84K、I-101)感染黑斑病和叶枯病进行了调查,并分析比较各个无性系的感病率、感病指数和相对感病指数。结果表明,白杨派A23、A46和A50对黑斑病抗病,黑杨派Pa和Ti对黑斑病抗病;白杨派A23、A39和A50对叶枯病高抗,A46和A54对叶枯病抗病,黑杨派Pa、Ti、Qg、 La、Ta均对叶枯病高抗。其中无性系A23、A50、Pa和Ti有较好的抗黑斑病和抗叶枯病能力,可以用作速生抗病性好的杨树新品种推广。
Abstract:
 An investigation was carried out on the disease resistance of 14 poplar clones(clone La,Pa,Ta,Qg,Ti,Zhonglin46,I-107,A23,A39,A46,A50,A54,84K,and I-101) to black spot and leaf blight at seedling stage.The infection rate,index,relative infection index of different clones tested were analyzed and compared.The results showed that clone A23,A46,A50 and Pa,and Ti were resistant to black spot disease,clone A23,A39 and A50 were highly resistant to leaf blight,and clone Pa,Ti,Qg,La,and Ta were highly resistant to leaf blight.Clone A23,A50,Pa,and Ti had good resistance to black spot and leaf blight,and could be used to popularize as new poplar varieties with good rapid growth and disease resistance.
