山茱萸胚和胚乳发育的初步研究

Preliminary Study on Development of Embryo and Endosperm of Cornus officinalis

山茱萸胚乳的发育类型为核型,种子为有胚乳种子。胚的发育可分为三个时期:原胚期—分化期(快速生长期)—成熟期,胚的生长呈S型曲线。淀粉在山茱萸胚、胚乳中的积累有顺序性。

Developping type of endosperm of Cornus officinalis is pit type and it hasseed with endosperm. Development of embryo is divided into 3 periods: period of originalembryo - differentiation period - mature period. Embryo growth is type-S curve. Accumul-ation of amylum in embryo and endosperm of Cornus officinalis is orderly.
