油松针叶萜烯组分相对含量同 环 境 和 生 长 因 子 的 关 系

A sudy on the relationships between the relative contents of needle volatile terpenes with environmetal and growth factors of Pinus tabulaeformis Carr

    摘要
  • 摘要: 在山西、河北、陕西和甘肃4省，选择油松12个种源的36个林分、288株成年油松样木。利用GC及GC/MS分析技术和相关、回归等方法，测定分析了油松针叶萜烯化合物相对含量以及化合物总数同环境因子和生长因子之间的关系。结果表明，化合物总数随海拔高度的升高而减少；部分化合物相对含量同环境因子存在相关关系；各化合物相对含量同油松高生长的单相关作用很小而存在复相关作用。

     

    Abstract: 288 samples of mature Pinus tabulaeformis Carr.,which belong to 12 varieties and 36 stands and collected from four provinces:Shanxi,Hebei,Shaanxi and Gansu were analysed by GC,GC/MS technicals and regression methods.The results showed that:1)with the increasing of elevation,the total number of terpenes contained decreased,2)there were certain correlation between environmental factors and relative contents of some terpenes，3)there was no relationship existing between the relative contents of any single terpene with the tree height growth,but synthetical correlation might exist.
