摘要
通过调查不同海拔锥栗林分和锥栗品种受栗瘿蜂危害的情况,研究海拔对锥栗抗栗瘿蜂性表达的影响。结果表明:高海拔不利于锥栗抗栗瘿蜂性的表达;品种抗栗瘿蜂性在不同海拔地区的表达程度与品种抗性大小有关,品种抗性越高,其抗虫性表达受海拔的影响越小,在高海拔地区越能体现其对栗瘿蜂的抑制作用。
The results showed that high elevation did harm to the resistance expression of Castanea henryi to Dryocosmus kuriphilus, the expression degrees of variety resistances to D.kuriphilus in the areas with different elevations were relative to the variety resistance degree,the higher the variety resistance was, the smaller the effect of elevation on the expression was, and the more fully its control effect on D.kuriphilus was reflected in the area with high elevation.
