| 摘 要： | 杨树不同品系对杨干象抗性差异很大,以美洲黑杨为亲本的多数外来品种对杨干象抗性差,也使杨干象种群迅速扩大。该文根据调查的3年生和4年生连续2 a的不同杨树品系的平均虫口密度,根据聚类分析的方法将其划分为高感虫品系、感虫品系、低抗虫品系、中抗虫品系和高抗虫品系5个级别,结合杨树品系的类型、形态特征等进行分析,为生产上选用杨树抗性品系和减少杨干象大发生的危害及抗虫育种等方面提供参考。 |
| 关 键 词： | 杨树品系 抗虫性 杨干象 |

| Abstract: | As it has marked difference on resisting Crptorrhynchus lapathi in different poplar strains.Pest density of different poplar strains with three or four yeas old was investigated.All poplar strains were divided to five grades by using method of cluster analysis.Based on our investigative data,type and morphological character of poplar strain,poplar resistant strains were elected and applied. |
| Keywords: | poplar strains pest resistance Crptorrhynchus lapathi |
