Anatomical structures and analysis of starch accumulation in fruit tree roots

在许多果树中，研究了与其发育相关的根的形态和解剖变化。不同土壤水分条件下，木参内胚层呈卡斯帕里斯带状，外胚层呈根伸长。特别地，研究了蔷薇科果树的phi增厚和木质素在靠近表皮和下皮层的皮层细胞壁的积累。本文报道了桃金娘科植物（飞果、腊苹果等）根中柱鞘细胞的两个解剖学特征：(1)经组织学检查证实，根中柱鞘细胞层呈里氏带；(2)在根中柱鞘细胞间存在厚壁细胞。

Morphological and anatomical changes in roots associated with their development were investigated in many fruit trees. The suberin lamellae formation with Casparian strip in endodermis and exodermis with root elongation under different soil water conditions. Particularly, phi thickening in Rosaceae fruit trees and lignin accumulation in the cell wall of the cortex near the epidermal and hypodermal layers was examined. Two anatomical features in cells derived from the pericycle of the roots in Myrtaceae(feijoa and wax apple etc.) were reported :(1) appearance of endodermis-like cell layer with a Casparian strip which was confirmed by histological examination and (2) occurrence of thick wall cell between endodermis-like cells.
