| 摘 要： | 樟子松(Pinus sylvestrisvar.mongolica)、赤松(P.densiflora)、油松(P.tabulaefor-mis)均属于松科、松属、双维管亚属中的油松组。它们的共同特征是:叶二针一束,叶鞘宿存,针叶内有两条维管束,树脂道边生。但是,他们在形态特征、针叶内部结构及生态生物学特性方面也有显著的区别。根据这些区别,以准确辨认这三种松树,在生态环境的建设改造中不致于选错树种,从而造成人力和经济上的损失。

| Abstract: | Pinus sylvestris var.mongolica,P.densiflora and P.tabulaeformis were Pinaceae,Pinus,Sect.Pinus of Subgen.Pinus.Their common characteristics were: two leaves in a fascicle,persistent sheath,two vascular bundles in needle-like leaf,but there were great differences on morphological features,internal structure of needle-like leaf and bio-ecological characteristics.According to these differences,three kinds of pine trees could be accurately identified. |
