日本石松（Pinuspumila Regel）是高山高寒地区的优势树种。对十八个 P. pumila 自然种群进行了研究，以确定遗传多样性的范围和分布。与其他针叶树相比，该物种内的遗传多样性程度较高（HT = 0.271），种群间的遗传分化也较高（GST = 0.170）。俄罗斯前期对P. pumila的研究表明，种内遗传变异也较高，但种群间遗传分化较低。我们推断，这种差异源于两国地理分布的差异和生态的差异。总体而言，每个种群内的遗传变异在南方边缘种群中往往比北方种群中要小。种群之间的遗传关系反映了地理位置，如算术平均值的未加权配对方法所示......
Japanese stone pine (Pinuspumila Regel) is a dominant species characteristic of alpine zones of high mountains. Eighteen natural populations of P. pumila were studied in an effort to determine the extent and distribution of genetic diversity. The extent of genetic diversity within this species was high (HT = 0.271), and the genetic differentiation among populations was also high (GST = 0.170) compared with those of other conifers. In previous studies of P. pumila in Russia, the genetic variation within the species was also high, but the genetic differentiation among populations was low. We infer that this difference originates from differences in geographic distribution and ecological differences between the two countries. The genetic variation within each population tended, as a whole, to be smaller within marginal southern populations than within northern populations. Genetic relationships among populations reflect the geographic locations, as shown by unweighted pair-group method with arithmetic means ...
