作为对昆虫取食的反应，番茄植株(Lycopsieon Esculentum)释放水平增加的挥发性有机化合物；即单萜和倍半萜在受伤的情况下局部和系统地释放，而C-6绿叶挥发性物质只从受损的叶片中释放，外源C-6-番茄挥发性(E)-2-己烯醛(100 Nmol)增加了局部和系统萜类的释放，而等摩尔量的茉莉酸甲酯只引发局部的萜类排放。(CO2)-C-13标记研究表明，化学处理或昆虫取食后立即释放的单萜或倍半萜不需要从头合成。对植物施加的乙醛剂量与受虫害的叶片自然释放的乙醛水平进行了比较测量。(C)2002爱思唯尔科学有限公司。保留所有权利。
In response to insect feeding, tomato plants (Lycopersieon esculentum) release elevated levels of volatile organic compounds; that is, monoterpenes and sesquiterpenes are released both locally and systemically with wounding while C-6 green leaf volatiles are released only from damaged leaves, With the exogenous application (100 nmol) of the C-6-tomato-volatile (E)-2-hexenal, an increase in the release of local and systemic terpenes was-observed, while an equimolar amount of methyl jasmonate triggered only local emissions of terpenes. Labeling studies with (CO2)-C-13 showed that de novo synthesis was not required for monoterpene or sesquiterpene release immediately following chemical treatment or insect feeding. Comparative measurements were made between aldehyde doses applied to the plant and levels naturally released from leaves with insect damage. (C) 2002 Elsevier Science Ltd. All rights reserved.
