摘    要: 【目的】探讨北方果树(枣、桃、樱桃、葡萄)叶片内生理代谢指标变化与绿盲蝽对其偏好度之间的关系,分析各种果树在虫害胁迫下自身生理防卫机制及耐害补偿机制的差异,为绿盲蝽综合防治提供依据。【方法】田间调查受绿盲蝽危害的不同果树的被害指数并确定偏好度,生物化学方法研究受绿盲蝽危害后果树叶片内生理代谢指标的变化。【结果】受害后除桃树叶片内可溶性糖含量明显下降外,其它果树叶片可溶性糖含量均增加,以枣树叶片增加最显著,增加率达87.83%;各果树叶片内蛋白质含量均呈下降趋势,除偏好程度较高的桃树叶片内蛋白质显著下降外,其它果树受害叶片内蛋白质含量与对照间均无显著差异;受绿盲蝽危害后,4种果树叶片游离氨基酸含量均增加,增加率与绿盲蝽危害指数之间存在一定的正相关性;受害后4种果树叶片内过氧化物酶(POD)活性均有增加趋势,其中枣树叶片增加最显著,增加率达112.92%;超氧化物歧化酶(SOD)活性仅樱桃树叶片内有所下降,其它果树叶片受害后SOD活性均有增加,枣树叶片增加最显著,增加率达40.95%;4种果树受害叶片内CAT活性均与对照间无显著差异。【结论】受绿盲蝽危害后4种果树叶片内不同生理代谢指标变化规律存在差异。4种果树叶片内可溶性糖含量、游离氨基酸含量、POD和SOD活性变化率与绿盲蝽偏好程度之间存在一定的正相关性;蛋白质含量和CAT活性与绿盲蝽对其偏好程度之间无明显的相关性。

Abstract:【Objective】 The objective of this study is to elucidate the relationship between changes of physiological indexes in different fruit tree leaves of jujube, peach, cherry and grape and preference degree of Apolygus lucorum, and to analyze the physiological defense mechanism of damaged leaves by A. lucorum, providing a scientific basis for effective control of the pest. 【Method】The damage indexes of different fruit trees were investigated in the orchard, and biochemical analyses were conducted to study changes of various physiological indices in damaged leaves of different fruit trees. 【Result】Soluble sugar contents increased in four fruit tree leaves except peach leaves after damaged by A. lucorum, and increased up to 87.83% in jujube leaves. The content of protein decreased in four fruit trees leaves, and no significant difference in protein was found between pierced and contrast leaves except peach leaves. Free amino acid contents increased in four fruit tree leaves, with the increase rate having a positive correlation with damage index, contrast to the piercing of A. lucorum. The POD activities in four fruit tree leaves showed an increasing trend, and increased by 112.92% in jujube leaves. The SOD activities increased in other tree leaves except cherry leaves, with a high increase rate of 40.95% in jujube leaves. No significant difference in CAT was found between pierced and contrast leaves of four fruit trees. 【Conclusion】After damaged by A. lucorum, the changes of physiological indexes in different kinds of leaves were different. The changes of soluble sugar, amino acid contents, POD and SOD activities showed a positive correlation with the preference of A. lucorum, while the protein contents and CAT activities showed no significant correlation with the preference of A. lucorum.
Keywords:Apolygus lucorum  physiological indexes  jujube  peach  cherry  grape
