以湖南省6个红榉种源（天然种群）为研究对象，对其木材基本密度和径向全干干缩率等物理性质进行测定分析。结果表明：不同红榉种源间木材基本密度的差异达极显著，而种源内木材基本密度比较稳定，变异较小；不同种源间木材径向全干干缩率不存在显著差异，但种源内不同个体间的差异显著。红榉木材基本密度与径向全干干缩率相关性不显著。这2个性状基本上相互独立遗传，且两者与各地理气候因子相关性也不显著。

Woods of six Zelkova schneideriana Hand-Mazz.provenances in Hunan Province were taken as research mate-rials,and such physical properties as basic density and radial dry shrinkage were tested and analyzed.The results showed as following:(1 )There were highly significant differences of the basic density among different provenances,while theirs CV were rather stable;(2 )There were no significant differences of radial dry shrinkage among different provenances, while the individuals within one provenance revealed rather higher difference;(3)Basic density was not closely related to radial dry shrinkage.The independent selection of basic density and radial shrinkage were expected to generate improved effects.And both of them had no significant correlation to the geographic and meteorological factors too.
