| 摘 要： | 为探讨植物挥发物的日动态变化,以樟树Cinnamomum camphora花为实验材料,采用动态顶空气体循环采集法和热脱附/气相色谱/质谱联用技术（TDS-GC-MS）,对5个时间点（7：30,10：00,12：30,15：00,17：30）樟树花挥发物进行收集鉴定。结果表明：樟树花释放挥发物中共检测出51种化合物,主要成分为萜烯类化合物。15：00时樟树花挥发物释放量及种类最多（40种,8 049.5峰面积单位）,主要有芳樟醇（相对含量37.0%）,环氧芳樟醇（12.7%）,（Z）-罗勒烯（7.2%）和紫苏烯（6.2%）;樟树花挥发物释放量及种类显著增加与受到强光和高温胁迫有密切联系。

| Abstract: | In order to make clear the diurnal variation of plant volatiles,we collected the VOCs from Cinnamomum camphora flowers using the dynamic headspace air-circulation method at 7:30,10:00,12:30,15:00 and 17:30,identified the main compounds of VOCs with thermal desorption system/gas chromatography/mass spectrum(TDS-GC-MS).Results showed that C.camphora flowers emitted 51 types of VOCs,mainly as terpenoids.At 15:00,species and emission of the VOCs were highest(40 species and 8 049.5 peak area units),mainly as lin... |
