The reduction of. light per cell caused by severe mutual shading in high cell density culture turn out to be the key reason. 上述造成叶绿素或细胞数量等指标有时反映出生长信息失真,主要是由于随着密度增高,细胞间的互相遮蔽作用加剧,单个藻细胞所能获得的光能逐渐减少导致的。
There was a certain degree of concentration and periphery in cytoplasmic of chloroplast cell under shading, but thylakoid and lamella structure of grana were almost complete. 遮光后叶绿体内细胞中胞质出现了一定程度的浓缩和周缘化,但类囊体与基粒片层结构尚为完整。
Different stage shadings all resulted in a significant decrease in the number of endosperm cell, the earlier shading began, the fewer the number of endosperm cell. 不同时期遮光均显著降低了籽粒胚乳细胞的数量,遮光处理开始的越早,胚乳细胞数量越少,其中初期遮光胚乳细胞数量最少。
