摘要
对寒旱区克拉玛依市的51个杨树种、品种(无性系)的杨二尾舟蛾危害指数和相对抗性指数进行了调查和分析,结果表明:除准噶尔3号属低抗水平外,其余50个种、品种(无性系)均属于中感和高感水平;不同杂交组合的相对抗性指数差异显著;同一杂交组合的不同种(或品种)间抗性也存在显著差异。
The pathogenic index and confrontational index of Cerura erminea with 51 poplar species or varieties (clones) of Kelamyi in cold and arid regions were investigated. The results showed that 50 poplar species or varieties (clones) indicated high susceptibility and medium susceptibility, but Junngar No. 3 indicated low resistance only. And the different poplar hybrid combinations from the same cross showed evidently diversity in resistance.
