摘要
根据枸树导管解剖结构，用统计学方法建立了桑科植物水分长距离运输阻力的生物物理模型。结果表明，枸树水分长距离运输阻力与导管长度倒数呈极显著的线性关系，这与实际情况相符。
In this study,because of the anatomic structure of woody plants,and from the statis-tical point of view,the authors derived the relation between water long-distance translo-cation resistance and vessel mean length.The relation is linear between resistance and re-versed figure of vessel mean length.In experiment.Papyrifera(diffuse-porous wood)was used.and the relation was proved between water long-distance translocation resis-tance and vessel mean length.
