摘要

对小青黑杨（PoPulus Pseudo-simonii Kitag.x p.nigra L.）和它的母本小青杨（Populus pseudo-simonii Kitag.）对比研究表明,在环境、树龄、经营措施等条件相同情况下,小青黑杨生长速度明显超过小青杨（快50%,见表1）,而解剖特征如木纤维形态、导管分子、组织比量等以及木材密度,则两者相近。生长轮增宽是细胞个数的增加。小青黑杨生长达到速生要求,但材质井未降低。

Abstract

This paper deals with the hybrid of Populus pseudo-simonii Kitag. x P. nigra L. in comparison with its parents of P.pseudo-simonii Kitag. The results show that hybrid grows faster than its parents and other features are not much difference, for example, fiber characteritics, vessel element characteristics, wood density and so on. These two poplar species can be used for paper making in juvenile trees. The increase of the width of ring is due to the increase of the number of cells.
