摘要: 中国东北部的落叶松属植物,在分类学上常被视为2个种[2,3]。然而对其种鳞的形态、正常种鳞的数量及针叶长度的研究统计结果表明,以上性状存在地理上的差异,然而又有明显的连续变异特征,证明长白山及东北东部分布的落叶松,在起源上晚于兴安落叶松(Larix gmelinii),应是兴安落叶松在东北东部的地理变异种。

关键词: 落叶松, 种鳞, 针叶, 地理变异

Abstract: Larix are often considered to have two species in northeast of China.But the statistic analysis of the shape of seed scales, number of normal seed scales and the length of needle leaves indicates:There are geographic differences and marked continuous variation features in all above characters.It demonstrated that:Larix that distributes in Changbai mountain and east area is later than Larix gmelinii in origin.In fact it is a geographic variation species of Larix gmelinii in northeast area.

Key words: Larix, Seed scales, Needle leaf, Geographic variation
