该文对梅果实发育过程进行了较系统研究.梅子房内着生二个半倒生胚珠,开花时,胚囊处于4至8核阶段.内果皮分三个层次,最内层的4~6层细胞明显纵向加长,它的硬化大约从花后40~45d开始.外果皮是一种复合结构,由表皮毛、表皮细胞、气孔器和数层下皮组织细胞组成.中果皮主要是薄壁细胞,靠近内果皮的数层中果皮细胞径向显著加长.大约在开花后35~40d,珠被体积达最大,细胞内含大量淀粉.初生胚乳核分裂比合子早,但一直到原胚发育成球形胚时,胚乳游离核才转变为胚乳细胞.以后,胚乳细胞又被迅速发育的胚所吸收和利用.该文对胚珠类型、珠孔塞起源、胚乳吸器及果实发育速度与胚胎发育的关系进行了讨论
In this paper, the development of plum fruit during a more systematic study. Mezi room with two and a half anteposing ovule, flowering, embryo sac in the 4 to 8 nuclear stage. Endocarp divided into three levels, the innermost layer 4 to 6 significantly longer vertical cells, its hardening about 40 ~ 45d after anthesis start. Exocarp is a complex structure composed of epidermal cells, epidermal cells, stomatal apparatus and several layers of subcutaneous tissue cells. The mesocarp is mainly parenchyma cells, and the pericarp cells in several layers near the endocarp significantly longer in the radial direction. About 35 ~ 40 d after flowering, the maximum volume of beads, the cells contain a large amount of starch. The primary endosperm nuclear division earlier than the zygote, but until the embryo developed into a spherical embryo, endosperm free nucleus was transformed into endosperm cells. Later, endosperm cells are rapidly absorbed and utilized by embryos. This paper discusses the relationship between the type of ovule, the origin of micropyramid plug, endosperm aspirator and the rate of fruit development and embryonic development
