摘要:
 以中国伏牛山脉木札岭和小兴安岭帽儿山2个区域的散孔材树种枫桦（Betula costata）为对象，研究落叶后树枝和树根木质部中非结构性碳水化合物(NSC)含量的地域差异。结果表明，帽儿山枫桦树根和树枝的可溶性糖与淀粉含量均>木札岭；2个区域枫桦树根的可溶性糖与淀粉含量均>树枝。枫桦非结构性碳水化合物的地区差异以及组织差异是树木在休眠期应对环境变化特别是温度变化的结果。
Abstract:
 Taking Betula costata,a tree species for the production of diffuse-porous timber occurring in Muzhaling of Funiu Mountain range,and Maoersan of Xiaoxinganling Mountain range as research object,this paper studied the regional variations of the non-structural carbohydrates (NSC) content in the xylem structures of branches and roots after leaf abscission.The results showed that the soluble sugar and starch contents of in the roots and branches of B.costata in Maoersan were higher than those of Muzhaling.The soluble sugar and starch contents in branches were higher than those of roots in both two regions.It was suggested that the differences in the contents of these non-structural carbohydrates between two regions,and two tree organs were the responses of the trees to environmental changes during the dormancy period,especially temperature change.
