锥栗对栗瘿蜂抗性与营养元素关系研究

通过测定不同抗性锥栗品种叶片N、P、K、Ca、Mg、Mn、Cu等7种营养元素的含量,研究锥栗品种对栗瘿蜂抗性与营养元素的关系。研究结果表明:K元素与锥栗品种的抗虫性有关,当锥栗受栗瘿蜂危害时,高抗品种植株内K含量下降到较低的水平,高感品种的K含量保持在较高的水平;N、P、Ca、Mg、Mn、Cu等6种营养元素与锥栗品种的抗栗瘿蜂性无关。

Relation between the Castanea henryi Resistance to Dryocosmus kuriphilus and Nutrient Element

Through the study of relation between the Castanea henry/ resistance to Dryocosmus kuriphilus and nutrient element, the results showed that K had the relationship with C. henry/ variety resistance, when C. henry/ was damaged by D. kuriphilus, K content decreased to the relatively low level inside the high-resistance variety plant, high sensitive variety K content kept in the relatively high level; 6 kinds of nutrient elements of N, P, Ca, Mg, Mn, and Cu had not the relationship with C. henryi resistance to D. kuriphilus.
