对杏果实发育过程进行了较系统的形态组织结构解剖学研究。结果表明 ,杏子房内有两个横生胚珠。果皮由外果皮、中果皮和内果皮构成。外果皮是一种复合结构 ,由表皮毛、表皮细胞和气孔器组成 ,中果皮主要是由薄壁细胞和分布其中的维管束组成 ,内果皮细胞经过分裂、分化形成 3种不同形态的细胞区域 ,最内部区域为垂直伸长的石细胞 ,中间区域为弦向伸长的石细胞 ,最外区域为等径的石细胞 ,其木质化顺序由外向内。合子细胞分裂经过球形胚和子叶形胚时期 ;胚芽的分化早于胚根
The apricot fruit development process carried out a more systematic anatomical study of anatomical structure. The results show that apricot room with two lateral ovules. The peel consists of exocarp, mesocarp and endocarp. Exocarp is a complex structure composed of epidermal cells, epidermal cells and stomatal apparatus. The mesocarp mainly consists of parenchyma cells and vascular bundles distributed therein. Endocarp cells divide and differentiate to form three different morphological cell regions , The innermost region is vertically elongated stone cells, the middle region is the chordal elongated stone cells, the outermost region is the equal size of stone cells, and the lignification order is from outside to inside. Zygote divisions through the spherical embryonic and cotyledon embryos; germ differentiation earlier than radicle
