| 摘 要： | 大豆开花后18～43天,子叶细胞含叶绿素。细胞内原质林可逐渐积累淀粉粒;基质内有基粒和基质片层。原质体发育为造粉质体。这种造粉质体属“绿色造粉质体”。开花后53～63天,造粉质体内淀粉粒数目减少,体积缩小;片层结构肿胀,并逐渐解体。造粉质体脱分化为原质体。造粉质体的分化和脱分化过程与蛋白质和脂类的积累密切相关。

| Abstract: | From 18-43 days after flowering (DAF), Chlorophyll was contained in amyloplasts of soybean cotyledon cells. In the stroma of amyloplasts there were some big starch grains, granal and stromel lamellae. In this'way, proplastids developed to amyloplasts, which is termed as " green amyloplasts". From 53-63 DAF, starch grains in amyloplasts decreased in number and in size. The lamellae in the stroma expanded and bxoke down. The process of amyloplasts differentiation and dedifferention is related to accumulation of storage protein and oil. |
