| 摘 要： | 根据分布于世界６个地区的松属５１个种的核型分析结果和每种松树的染色体长度比以平均臂比绘制了核型演变图．作者认为松属的核型进化趋势是：（１）由对称类型往不对称的类型进化；（２）双线管束亚属是由单维管束亚属演变而来的；（３）松属种间具有一致的起源；（４）白皮松的核型是属于单维管束亚属往及维管束亚属过渡的类型．

| Abstract: | The results of karyotype analysis of 51 species of genus pinus in the six districtsof the world are reported in this paper. According to the data about shape,anatomy and geography distribution etc.,the karyotype evolution of genus pinus tends to be as follows:1) It evolves from symmetrical karyotype to asymmetrical one;2) Sugen Pinus is evolved from Subgen Strobus;3) Different species of genus pinus share the same origin;4) The karyotype of P.bungeana is one transiting from Subgen Strobus to Subgen.Pinus. |
