枣树根、枝细胞和叶片栅栏、海绵组织细胞具有体积较小、排列紧密、胞壁及导管壁较厚、导管密度极小的特点。由此导致枣树组织坚硬、木质致密、不易失水、生长量小、增粗缓慢、较抗干旱的生理、生态特性。枣树的构造反映了自根果树的解剖学特点。 Jujube root, branch cells and leaf fence, sponge cells with smaller, closely arranged, thicker cell wall and catheter wall, catheter density is extremely small. As a result, the jujube tissue is hard, dense and hard to be dehydrated, its growth rate is small, thickening slowly, and more resistant to drought than the physiological and ecological characteristics. Jujube tree structure reflects the anatomical characteristics of self-rooted tree.
