通过对8种苹果砧木的根、枝、叶组织解剖构造的研究,提出了上述各项组织构造与体积大小有关的解剖学指标。指出以一个指标决定砧木的矮化程度有其局限性;认为砧木根和枝的材皮比,导管密度,枝内导管占木质部百分率,叶的栅海比,可作为苹果砧木矮化性状的综合解剖学指标。
Through the anatomy of the root, branch and leaf tissue of eight kinds of apple rootstocks, anatomical indexes related to the size and structure of the above tissues were proposed. It is pointed out that there is a limitation to determine the dwarfing degree of rootstock with one index. It is considered that the ratio of root / shoot to root / shoot, the density of the tube, the percentage of xylem in the branch and the ratio of grate to leaf of the rootstock can be used as the comprehensive anatomy of dwarfing Learning indicators.
