摘要
利用气相色谱和气质联用分析技术,对陕西省宁陕县旬阳坝林场8株成年油松的针叶挥发性萜烯化合物相对百分含量的季节变化进行了测定。结果表明,18种主要化合物的相对含量中有11种存在着显著或极显著的季节性差异,这种差异主要发生在夏季与冬季之间。
he seasonal variation of foliar volatile terpenes of Pinus tabulaeformis were determinated. The needle samples were collected in Xunyangba , Ningshan County,shaanxi Province from Noveinber of 1984 to November of 1985 in every two months. The results indicated that there were significant seasonal variations on relative contents in 11 of total 18 volatile terpenes.The difference occured mainly between summer and winter.
