| 摘 要： | 对干旱胁迫下3a生复叶槭的挥发物进行了鉴定。当复叶槭受到干旱胁迫时，9种化合物释放量升高(包括：丁醇、戊醇、反—2—己烯—1—醛、顺—3—己烯—1—醇、戊醛、戊酸、己醛、己酸、苯乙酮)，而长叶烯释放量降低：复叶槭复水后苯乙酮升高，但其他挥发物释放量降低。通过GC—EAD检测了光肩星天牛对其中某些化合物的触角电位反应，并使用诱捕器和人工合成单体进行了田间生测实验。丁醇、戊醇和顺—3—己烯—1—醇能引起光肩星天牛的触角反应，这一结果在田间实验中得到了证实。这表明干旱胁迫在光肩星天牛选择寄主植物方面起着重要作用。 |

| Abstract: | The volatile organic compounds emitted from 3-year-old ash-leaf maple seedlings (Acer negundo) under drought stress were identified. Emissions of nine volatile compounds, including butyl alcohol, pentyl alcohol, trans-2-hexen-1-al, cis-3-hexen-1-ol, pentanal, pentanoic acid, hexanal, hexanoic acid, and acetophenone, increased and a tenth compound, longifolene, decreased when the trees were subjected to water stress. After the trees were re-watered the amount of acetophenone increased, but the amounts of other volatiles including longifolene decreased. The response of Asian longhorned beetle (ALB, Anoplophora glabripennis M.) to volatiles was examined with GC-EAD, and with field bioassay using traps and synthetic compounds. Butyl alcohol, pentyl alcohol and cis-3-hexen-1-ol, elicited antennal responses from ALB. The activity was confirmed in the field test. Thus, drought stress appears to play an important role in the host selection behavior of ALB. |
