Natural populations of Picea glehnii distributes in various altitudes from lowland nemoral (300m asl.) to alpine zone (1400m asl.) in central Hokkaido. We investigated morphological and physiological traits of needles from these natural populations ranging from 300m to 1400m asl.Clines along the altitude were detected in both morphological (needle density and thickness) and physiological traits (the ratio of chlorophyll a+b / nitrogen). Since the similar clines were observed in altitudinal transplant replications (530, 730, 930, and 1100m asl.), phenotypic plasticity might be one of the causes of this altitudinal differences. We found that Abies sachalinensis showed strong local adaptation to the original altitudinal zones in the same mountainous slope through the reciprocal transplant experiments. Therefore, we concluded that the extent of genetic adaptation to altitude of P. glehnii was lower than that of A. sachalinensis. Subsequently, we used microsatellite and allozyme markers, in order to evaluate genetic differentiation among populations of P. glehnii and to detect non-neutral loci against natural selection along the altitude. The extent of genetic differentiation obtained by microsatellite markers was lower than that by allozyme markers. None of microsatellite loci were related to the environment. In contrast, certain allozyme variation was detected only in alpine population. Previous studies had revealed that seedling growth from dwarf populations in alpine zones was significantly lower than that from middle-altitude populations. These findings indicated that dwarf populations in alpine zones might be different ecotype from other populations of P. glehnii in central Hokkaido.

云杉天然种群分布于从低地到海拔300 m的不同海拔高度。到高山区（海拔1400米）位于北海道中部。对海拔300 ~ 1400 m的天然群体针叶的形态和生理性状进行了研究，结果表明，针叶的形态（密度和厚度）和生理（叶绿素a+B /氮）均存在沿着海拔梯度的变异。由于在海拔530、730、930和1100米的移植重复中观察到类似的渐变，表型可塑性可能是造成这种海拔差异的原因之一。通过对高山冷杉的倒栽试验发现，高山冷杉对同一山坡地的原始海拔带具有较强的局部适应性。因此，葛氏松对海拔高度的遗传适应程度低于蒙古松。sachalinensis。随后，我们利用微卫星和等位酶标记，以评估居群间的遗传分化和检测非中性位点沿沿着海拔的自然选择。微卫星标记所获得的遗传分化程度低于等位酶标记。没有微卫星位点与环境相关。与此相反，某些等位酶的变异，仅在高山种群。以往的研究表明，高寒地区矮生种群的幼苗生长显著低于中海拔种群。这些结果表明，高山地区的矮生居群可能是不同于北海道中部其它居群的生态型。
