Abstract

The content of nonacosan-10-ol and n-alkanes in needle waxes of 12 Pinus taxa (P. halepensis, P. heldreichii, P. mugo, P. nigra ssp. nigra, P. nigra ssp. dalmatica, P. peuce, P. pinaster, P. pinea, P. ponderosa, P. strobus, P. sylvestris and P. wallichiana) were examined. In eight Pinus taxa (except of P. halepensis, P. pinaster, P. heldreichii and P. peuce) nonacosan-10-ol contents were examined for the first time. In all examined pines C29, C27 or C25 were the main n-alkane compounds. C range was mainly 18-–33. In six Pinus taxa (P. mugo, P. nigra ssp. dalmatica, P. sylvestris, P. pinea, P. strobus and P. wallichiana) carbon preference index and average chain length values were examined for the first time. In the plane of Axis 1 (PCA), P. strobus, P. mugo and P. wallichiana were strongly separated from P. heldreichii and P. pinea. In the plane of Axis 2, P. peuce, P. strobus and P. wallichiana as well as P. heldreichii and P. pinea diverged from other examined species. In DA, P. heldreichii, P. strobus, P. peuce and P. wallichiana diversed. CA divided sections Pinus and Pinaster from the section Strobi.

摘要

12种松属( P. halepensis , P.heldreichii , P. mugo , P. nigra ssp. nigra , P. nigra ssp. dalmatica , P. peuce ,对P. pinaster、P. pinea、P. ponderosa、P. strobus、P. sylvestris和P. wallichiana ) 进行了检查。在 8 个Pinus 类群中（除P. halepensis、P. pinaster、首次检测了P.heldreichii和P. peuce ) nonacosan-10-ol 含量。在所有检查过的松树中，C29、C27 或 C25 是主要的正构烷烃化合物。C范围主要是18--33。首次检测了6 个Pinus分类群（P. mugo、P. nigra ssp. dalmatica、P. sylvestris、P. pinea、P. strobus和P. wallichiana ）的碳偏好指数和平均链长值。在轴 1 (PCA) 平面上，P. strobus、P. mugo和P. wallichiana与P.heldreichii和P.pinea。在轴 2 的平面上，P. peuce、P. strobus和P. wallichiana以及P.heldreichii和P. pinea与其他检查的物种不同。在DA中，P.heldreichii、P. strobus、P. peuce和P. wallichiana多样化。CA 将Pinus和Pinaster部分与 Strobi部分分开。
