摘要/Abstract

摘要： 梨上瘿螨Epitrimerus pyri (Nalepa)为害苹果梨Pyrus bretschneideri Rehd.叶片后，一些生理生化指标发生了变化。经光谱技术、化学方法和电物理方法测定，与健康叶片相比受害部位的叶绿素含量下降50.05%，可溶性糖含量下降19.86%，可溶性蛋白质含量上升29.17%，游离氨基酸含量上升21.59%，游离脯氨酸含量上升107.03%，过氧化氢酶活性增加22.62%，膜透性增加150.43%，而且受害部位周围组织的生理生化指标也发生了变化。

Abstract: Several physiological and biochemical indexes of leaves of Pyrus bretschneideri Rehd injured by Epitrimerus pyri (Nalepa) were measured. The results showed that, comparied with the normal leaves, the chlorophyll and soluble sugar of the infested leaves decreased by 50.05% and 19.86% respectively; and the soluble protein ,free amino acid， free proline, the activity of hydrogen peroxidase and the membrane permeability of the infested leaves increased by 29.17%, 21.59%,107.03%, 22.62% and 150.43% respectively by the means of the analysis of spectrum, chemistry and electric physics.
