| 于2002-2006年，对吉林省现行推广的杨树品种烂皮病的发生原因、发病规律及抗性差异进行调查,在此基础上进行防治试验。结果表明，在各品种的适生区域内，晚花杨(Populus×eurameicana‘Serotina’)、格尔里杨(Populus×curameicana‘Gelrica’)、西+加杨(Populus suaveolens+P.canadensis)、黄快杨(Populus simonii×P.pyramidalis ‘Huangkuai’)、白林2号杨(Populus‘Bailin-2’)及中延1号杨(Populus ‘Zhongyan’)高度抗病；中绥12号杨(Populus deltoides × P.cathayana ‘Zhongsui-12’)、大青杨优良无性系(Populus ussuriensis ‘ Jilin’)较抗病；大青杨(Populus ussuriensis)、银中杨(Populus alba × P.berolinensis)中度感病；迎春5号杨(Populus nigra × P.simonii‘Zhonglin Sanbei-1’)、北京杨(Populus pyramidalis × P.cathayana)、小×黑杨(Populus pseudo-simonii×Populus nigra)、吉林杨（山地1号）(Populus deltoids ‘Jilinsis’)、长林1号杨(Populus×beijingensis‘Changlin-1’)欧美杨107(Populus×euramericana ‘Neva’)、欧美杨108(Populus×euramericana‘Guariento’)易感病。对发病率在50%以上的造林地，应采用苗木平茬处理措施；当杨树幼林地苗木发病率在50%以下时，以21%过氧乙酸水剂（1∶10）、10%混合氨基酸铜络合物（1∶10）和50%多菌灵（1∶25）涂干防治可取得较好效果。其中以21%过氧乙酸水剂（1∶10）防治效果最好，为82%~95%。 |
| 英文摘要: |
| Cytospora canker of poplars is a common and serious trunk disease of seedlings and young trees in Jilin Province.In 2002-2007, the authors investigated the causes for the disease occurrence, epidemic pattern and different resistance among the present poplar cultures in Jilin.Among the poplar varieties, Populus×eurameicana ‘Serotina’, Populus×curameicana ‘Gelrica’, Populus suaveolens+P.canadensis, Populus simonii×P.pyramidalis ‘Huangkuai’, Populus ‘Bailin-2’ and Populus ‘Zhongyan’ are highly resistant, and Populus deltoides×(P.cathayana‘Zhongsui-12’) and Populus ussuriensis ‘Jilin’ are moderately resistant; Populus ussuriensis and Populus alba×P.berolinensis are moderately susceptible, and Populus nigra×P.simonii ‘Zhonglin Sanbei-1’, Populus pyramidalis×P.cathayana, Populus pseudo-simonii×Populus nigra, etc.are susceptible.The results of tests for controlling the disease showed that when over 50% of the young trees were infected with the disease, the plantation should be cut, but if less than 50% of the young trees were infected, the plantation could be controlled by chemicals.In the liniment tests, 21% peracetic acid AS (1∶10) was better than 10% cupric amino acid complex AS (1∶10) and 50% carbendazim WP (1∶25), with the control efficacy between 82%-95%. |
