摘要: 松科的系统发育研究历来已久,但由于性状进化的不同步性和属间进化缺少中间环节,致使科的分类系统和各属之间的演化关系至今未得到令人满意的解决。本文在钻研已有文献的基础上,筛选出松科属间综合分类性状36个,有序进化性状20个,借助计算机,以属为分类单位,进行表征分析研究确定松科分类系统,结果将松科分为三个亚科:松亚科Subfam.Pinoideae:仅Pinus Linn;落叶松亚科Subfam.Laricoideae Melchior & Werderm.emend.N.Li ex L.K.Fu:含四属:Cathaya Chun & Kuang, Larix Mill., Picea A.Dietr., Pseudotsuga Carr.;冷杉亚科Subfam.Abietideae Pilger, emend.Frankis:含五属:Abies Mill., Cedrus Trew, Keteleeria Carr., Pseudolarix Gordon, Tsuga Carr.。运用分支分析探讨各属的演化关系,并综合表征和分支分析结果,结合古植物学资料,构思和绘出了以地质年代为纵作标的松科系统发育树。

Abstract: The systematic studies of the family Pinaceae Lindl. is made by means of cluster analysis based on 36 systematic characters. The results indicate that the family is divided into three subfamilies:Subfam.Pinoideae:only one genus:Pinus Linn.; Subfam.Laricoideae Melchior & Werderm. emend. N.Li et L. K. Fu.:includes four genra:Cathaya Chun & Kuang, Larix Mill., Picea A. Dietr., Pseudotsuga Carr; Subfam. Abietoideae Pilger, emend. Frankis:include five genra:Abies Mill., Cedrus Trew, Keteleeria Carr., Pseudolarix Gordon, Tsuga Carr.The inter-generic evolutionary relationships in the family is also studied by means of cladistic analysis based on 20 polarizing data, taking geologic time as a longitudinal coo rdinate, a dendrog ram showing the probable phylogenetic relationships of the family is presented in this paper.
