| 摘 要： | 从24个油松种源单株采集2年生枝条上的针叶,进行单萜烯组分分析,研究种源综合萜烯组分变异性与地理空间变异的关系。结果表明:茨烯相对质量分数在种源间的变异幅度较大,其相对质量分数的差异在油松全分布区范围内存在着显著的地理变异趋势。油松种源差异显著,可分为北部类群、中部类群、西南类群和山东类群等4个类群,类群间单萜烯组分分化显著。观察到α-蒎烯、茨烯和β-蒎烯等成分的质量分数与其种源产地经纬度有机明显的地理变异规律。

| Abstract: | With two-year shoots of needles from 24 provenances of Chinese pine tree, by monoterpene component analysis, we studied the relationship between a source component variant specific integrated terpene and geographical space.Camphene relative content variation among provenances was larger, and there was significant geographical variation trend for the relative content in a significant range of the distribution area of Pinus tabulaeformis.There are significant differences between provenances of P.tabulaeformis, which can be divided into four groups including the northern group, the central group, the southwest group and the Shandong group, and the groups of monoterpene components are significantly differentiated.There is obvious geographic variation between the contents of α-pinene, camphene and β-pinene and other ingredients, and the latitude and longitude of the origin source. |
