摘要: 从中国东北的大兴安岭、小兴安岭、张广才岭及长白山地区采集落叶松球果进行了测定分析,结果表明:大兴安岭和小兴岭的落叶松球果,其形态多呈椭圆形,相对稳定,变异较小。张广才岭和长白山的落叶松球果多呈广卵形和卵形,变异较大。球果的长度和宽度性状较不稳定,不宜作为东北地区落叶松属内种间分类的依据。

Abstract: Cones of Larix, collected from Daxingan Mountain, Xiaoxingan Mountain, Zhangguangcai Mountain and Changbai Mountain, were measured.The results indicate that most of cones in Daxingan and Xiaoxingan Mountain show elliptic and there is lower variation, that in Zhangguangcai Mountain and Changbai Mountain show oval and ovate and there is higher variation.They should not be regareded as taxomic evidence for Larix in Northeast of China because length and width of cones are variable.

Key words: Larch, Larix gmelinii, Larix olgensis, Cones
