| 摘 要： | 通过对不同抗性的杨树寄主在不同接种时间段的木质素的沉积进行了跟踪。染色后观察发现:在受到落叶松-杨栅锈菌侵染后1～2d不亲和组合叶肉组织中木质素积累就很多,3d后积累比较明显。木质素积累的整个进程基本表现为木质素积累在近免疫、高抗品种较多,感病品种中很少,而免疫品种中无明显变化。

| Abstract: | The lignin deposition in the leaves of host poplars with different resistance in different inoculation durations was traced by dyeing methods.It was found that after the infected by Melampsora larici-populina Kleb.,the lignin accumulation in the 1~2 d mesophyll tissue of incompatible combination was very little,while the accumulation after 3 d was relatively obvious;the whole processes of lignin accumulation basically appeared as more in nearly immune and high resistance varieties,very little in susceptible varieties and no obvious change in immune varieties. |
