摘　　要：杨树菌溃疡病已在东北杨树栽培区大面积发生。黑杨派、青杨派与黑杨派、黑杨派与青杨派的杂交种危害严重,其中以黑杨派的钻天杨、箭杆杨和黑杨派与青杨派的杂种北京杨、美×青高度感病树种,引起肿茎溃疡,损失严重。过去的造林已失败。通过抗病品种的调查,证明以小叶杨为母本的青杨派与黑杨派杂交种小钻类(包括小黑×黑小)具较高的抗逆性。通过症状观察、病原菌分离培养、过敏性反应和接种试验进行了病害诊断检测和玻片凝集反应,对健康和感病的样株进行了初步的血清学对照检测。The bacterial canker of poplars occurred throughout most of Northeast areas for poplar culture in China. Damaged Aigeiros section and intersection hybrids whithin Aigeiros and Tacamahaca sections. Populus pyramidalis, P. nigra var. thevestina belonging to Aigeiros section and P. pyramidalisx P, cathayana cv, Beijinensis, P. nigrax P. cathayana belonging to hybrids of Aigeiros(♀) and Tacamahaca sections are high susceptible. This disease causes swollen stem canker, brings about great losses and failure of afforestation, the hybrid (P. simoniixP, pyramidalis and P. sirnoniixP. nigra) are screened as high synthetical resistant (disease, pest, frozen). The disease diagnoses are made by symptom pathogenic isolation and culture, hypersensitive reaction and artificial inoculation on poplars, an initial serological test is done to detect healthy or infected samples by slide aggutination reaction.
