自然状态下黄山贡菊植株挥发性化学物质成分及生态功能

Identification of Volatile Chemical Components from Dendranthema morifolium cv. Gongju in Fields and Ecological Function

摘要: 对黄山贡菊植株采用动态顶空套袋采集法结合GC-MS分析技术，成功地采集和分析了黄山贡菊在自然状态下挥发性化学物质的成分。共确定了59种有机化学物质，包括30种烷烃类、5种酯类、4种醇类、3种醛类、4种烯烃类、1种醚类及3种酮类等。室内Y型管选择行为测试结果表明，α−蒎烯≥600 ng/μL时，对3龄若蚜具有显著的驱避作用（P<0.05）。研究为基于植物化学物质的黄山贡菊蚜虫综合治理提供了理论基础。

Abstract: Volatile chemical components of Dendranthema morifolium cv．Gongju in fields were successfully collected and analyzed by dynamic headspace bagging collection method combined with GC-MS analysis technology．59 volatile chemical components were identified, including 30 alkanes, 5 esters, 4 alcohols, 3 aldehydes, 4 olefins, 1 aether and 3 ketones．Test results of indoor Y-shaped tube selection behavior indicated that, when α−Pinene ≥ 600 ng/μL, it has a significant repellent effect on 3rd instar aphids（P<0.05）．It provided a theoretical basis for integrated management of tribute chrysanthemum aphid in Dendranthema morifolium cv．Gongju based on phytochemicals．
