摘    要:对北京地区28种常见树种树皮及枝皮进行了解剖研究,结果表明,研究的4种裸子植物树皮的韧皮部均无典型韧皮纤维而有树脂细胞,在24种被子植物韧皮部中均有典型韧皮纤维。根据周皮与次生韧皮部是否交互排列,把被子植物分为两类,在这两类中又根据周皮层数与韧皮纤维排列各分成3个类型。另外,白皮松、红松在韧皮部树脂细胞层数明显,旱柳、国槐、刺槐、毛白杨、加杨的韧皮纤维束数与年龄大致相当,可作为树龄测定依据,但对许多其他类型,不太适合。

关 键 词:树皮形态 解剖构造 树皮年轮

Abstract:In this paper, anatomical studies on barks and barks of branches of 28 common tree species in Beijing region were conducted. The results showed that: phloems of barks of 4 gymnosperms studied had no typical phloem fibres but had resin cells. There were typical phloem fibres in phloems of 24 angiosperms. On the basis of whether peripheral bark and phloem arranged reciprocally, angiosperms were classified into two groups, 3 types were further classified respectively in each group according to layers of peripheral bark and arraying of phloem fibre. Meanwhile, layers of resin cells in phloems of Pinus bungeana and Pinus koraiensis were apparent, and numbers of phloem fibre bundle were about the same as the ages of Salix matsudana,Sophora japonica, Robinia peseudoacacia, Populus tomentosa and Populus canadensis, these could be the basis for measurement of ages, but were not suitable to other types.
Keywords:bark   morphology   anatomical structure   year rings of bark
