东北两种桦木导管和纤维细胞特征及其与气候关系
characteristics of tree trunk xylem vessels and fibre cells of two species of Betula in northeast China and their relationships with the climate
[目的]明确桦木属树种在气候影响下,树干导管及木纤维细胞对气候的响应与适应策略,从而更好地理解宏观生长-气候关系,为预测东北地区温带森林生产力与植被生产力提供理论基础与科学依据。[方法]本研究主要以黑龙江凤凰山国家森林公园内的白桦(Betula platyphylla)和枫桦(Betula costata)为研究对象,运用树木年代学和木材解剖学方法,测量并比较了 2 种桦木年轮宽度(RW)、导管数量(VN)、平均导管面积(MVA)、导管总面积(T…查看全部>>
[Objective]To clarify the response and adaptation strategies of trunk conduits and wood fibre cells of Betula spp.to climate under the influence of climate,so as to better understand the macroscopic growth-climate relationship,and to provide theoretical basis and scientific evidence for the prediction of the productivity of temperate forests and vegetation productivity in Northeast China.[Method]In this study,we measured and compared the annual ring width(RW…查看全部>>
