吴茱萸果实中分泌囊的发生和发育研究

吴茱萸果皮内分布有许多分泌囊。我们作了发育解剖学方面的研究。在花蕾期,雌蕊的子房中分泌囊原始细胞即开始发生,它起源于单个表皮细胞和其内的1—4层薄壁细胞。分泌囊最初为裂生,后期由于上皮细胞的破毁,其腔隙逐渐扩大,因此,腔隙发生方式应属裂溶生型。成熟分泌囊是由多层鞘细胞和上皮细胞包围圆形腔隙构成。

THE ORIGINATION AND DEVELOPMENT OF SECRETORY CAVITY IN THE FRUIT OF EVODIA RUTAECARPA

Many secretory cavities are distributed in the peel-of Evodia rutaecarpa (Juss.) Benth. The initial cells form in flower bud. They are derived from a single epidermal initial and one to several layers of perenchyma cells. At the early period, the oil chamber is schizogenous type. With the further expansion of chamber, a few of secretory cells free from the neighouring cells and disintegrate in the chamber. So the chamber should be schizo-lysigenous type, A mature secretory cavity is composed of several layers of sheath and epithelial cells which surround a chamber.
