The results indicated that, at the coenocyte and cellularization stages, active ATPase was mainly distributed in an embryo sac wall, nucleus, and plasma membrane. 结果表明,在胚乳游离核期和细胞化期,胚囊壁、细胞核和质膜上有ATP酶活性分布。
Cellularization of endosperm coenocyte starts from the wall of central cell to the middle of that cell. 胚乳的细胞化过程从中央细胞细胞壁的附近,向逐步细胞中央推进。
