薄皮马尾松调查研究初报

PRELIMINARY INVESTIGATION OF THIN BARK MASSON PINE

对湖北省宜昌地区的薄皮马尾松进行调查研究表明,薄皮马尾松在形态特征、解刮结构及木材物理力学性质等诸方面,都与普通马尾松存在较大差异,可认为是马尾松的一个变种。它生长快、树干通直、材质好,比普通马尾松具有更为优良的性状和更高的经济价值,且具有较稳定的遗传性状。经进行PCA分析,证明其皮薄具有独特效应,是优良的松树种质资源,应予引起足够的重视,加强保护和开发利用。

Investigation on the thin bark masson pine in Yichang Prefecture, Hubei Province indicates that it varies greatly from the common masson pine in morphological character, anatomical structure, and physical and mechanical properties. It is known as a variety of the common masson pine. The variety grows fast. with a straight bole and good wood property, and with better character, higher economic value; and more stable genetic traits. The analysis of PCA demonstrates that its thin bark has a unique effect, and it is a superior pine gene resource to which great importance must be attached in order to strengthen its protection and exploitation.
