窝梨(PyrusbretschneideriRehd.cv.Wo-Li)果实是由托杯和子房共同发育形成的假果。其横切面上,由外向内可看到表皮层、果肉、果心等几部分。表皮层、果肉由托杯发育而来,其中分布着维管束及石细胞等,果心是由子房发育而成,子房下位,5心皮组成5室,每室具2个倒生胚珠。表皮层的表皮细胞早期排列整齐,上有薄的角质膜,后期排列不规则,角质膜增厚并填充于表皮细胞之间;皮孔由气孔处发生,后期变为果点;果肉中的薄壁细胞前期排列紧密,后期排列疏松,近表皮处有丹宁层,丹宁层有少—多—少的变化趋势,果肉中分布着许多维管束及石细胞团,石细胞团由薄壁细胞转化而来,近表皮处小,近果心处大,影响食用品质
Pear (Pyrus bretschneideriRehd.cv.Wo-Li) fruit is a false fruit formed by the co-development of hypanthium and ovary. The cross-section, from the outside to the inside can see the epidermis, pulp, fruit and other parts. Epidermis, the flesh is developed from hypanthium, which is distributed with vascular bundles and stone cells, fruit heart is developed by the ovary, ovary inferior, 5 carpels composed of 5 rooms, each with 2 inverted ovules. Epidermal cells of the epidermal cells were arranged neatly on early, with thin keratinocytes, irregularly arranged in the later stages, thickening of the cuticle and filling in the epidermal cells; lenticels occurred at the stomata and became fruit spots in later stages; Parietal cells arranged in close pre-arranged late loose, near the epidermis with tannin layer, tannin layer less - more - less changes in the distribution of many vascular bundles and stone cell mass, the stone cell mass by the parenchyma cells Transformed from near the epidermis at a small fruit center near the big impact on food quality
