摘　　要：以砀山酥梨为材料,对梨果实发育过程中石细胞形成、石细胞团增大及薄壁细胞膨大过程进行解剖学研究。结果表明:梨石细胞先由果肉细胞壁不均匀加厚,进而形成厚壁细胞。石细胞形成始于花后15d,此后一周内形成大量石细胞;花后23d,石细胞聚簇,石细胞团大量出现,石细胞团直径增大;花后67d,石细胞团直径最大,此时薄壁细胞以长条状和椭球状两种方式膨大。梨果实发育过程中,石细胞含量先上升后下降,花后51d,石细胞含量达18.95%,以后石细胞含量下降。石细胞含量的下降是由于果实生长和薄壁细胞膨大引起的相对下降。It was anatomic studied enlarging of stone cell group and the expanding of parenchyma cells during fruit development of Pyrus bretschneideri. The results indicate ： Unequal thickness of fruit parenehyma cells＇ wall forms thick wail cell, thick wall cells develop to stone cell through cell wall re-thickness; The forming of stone cell mostly starts at 15 DPA and it commences largely within a week. The stone cells gather and emerge at 23 DPA and the diameter of stone ceil group enlarges. The max diameter of stone cell group comes forth at 67 DPA. At the same time, the parenchyma ceils grew and enlarged with two different methods, strip and ellipsoid. The content of stone cell increases firstly, and then descends during pear fruit development. The max content of stone cell come forth at 51 DPA （ 18.95% ）. The content of stone cell is determined the forming of stone cell and the expansion of parenchyma ceils during fruit development.
