通过对沙田柚根、茎、叶初生结构及其发育成次生结构过程作连续石蜡切片观察发现：沙田柚根的初生结构为１０原型．内皮层细胞卡氏带加厚不明显．根毛区近轴端稍后，维管形成层由初生木质部和初生韧皮部之间薄壁细胞转化形成，茎中维管束环形排列，在茎顶端第二节间，维管形成层环已开始活动形成了茎的次生结构．叶的栅栏组织由多层细胞组成，主脉维管束为周韧型，维管束外围绕一环石细胞．在叶的栅栏组织和表皮下有溶生分泌腔分布，但在根中未发现．
Through the continuous paraffin section observation of the primary structure of the roots, stems and leaves of Shatian pomelo and its development into secondary structure, it was found that the primary structure of the root of Shatian pummelo was 10 prototypes. Endocardial cells with thicker card is not obvious. Shortly after the paraxial region of the root hairs, the vascular cambium is formed by the transformation of parenchyma cells between primary xylem and primary phloem. The vascular bundles in the stem are arranged in an annular pattern. At the second intima of the stem, the vascular cambium has begun to form The secondary structure of the stem. The palisade tissue of the leaf is composed of multiple layers of cells, the main vascular bundle is of the tough type, and the outer vascular bundle is surrounded by a ring of stone cells. Distribution of lysosomes in palisade tissue and epidermis of leaves, but not found in roots.
