Data from: Scaling of phloem structure and optimality of photoassimilate transport in conifer needles

Conifer needle phloem geometryThis data contains the measurements for phloem geometry (number of sieve tubes, sieve tube area as function of distance from the tip) for 3-6 needles of four conifer species (Abies nordmanniana, Pinus cembra, Pinus palustris, Picea omerika)DataSupplement.zip

针叶树针叶韧皮部几何数据集
本数据集收录了4种针叶树（Abies nordmanniana、Pinus cembra、Pinus palustris、Picea omerika）的3~6枚针叶的韧皮部（phloem）几何参数测量数据，测量指标包括筛管（sieve tubes）数量以及筛管面积随距针叶顶端距离的变化规律。数据集文件为DataSupplement.zip。
