两系杂交稻籽粒充实度细胞学观察

从水稻颖果边缘向中部的胚乳细胞依次形成淀粉粒，且淀粉粒的数目和直径均依次减少。中部的胚乳细胞有两种情况（１）形成了少量淀粉粒后，细胞核解体消失，成为死细胞。淀粉粒的数目和直径保持在死亡前的状态．（２）还没有形成淀粉位前，细胞核已解体消失，成为死细胞。假如每个胚乳细胞中各自增加几个淀粉粒，且淀粉粒的直径增大，或者中部胚乳细胞能像边缘的胚乳细胞一样，那么，水稻大幅度增产是可能的．

Cytological Observation of Grain Plumpness in "Two-Lined" Hybrid Rice

The starch grains are formed from the fringe to the core of rice caryopsis serially, and their number and diameter also reduce serially. Endosperic cells of the core have two circumstances. 1. Nucleuses break down and disappear after forming a few of starch grains, and endosperic cells die, but the number and diameter of starch grains keep in the same state as endoperic cells are living. 2. Before starch grains are formed the nucleuses have broken down and disappeared, and made the endosperic cells die. Great increase in rice production would be possible, if several starch grains increase in every endosperic cell, and the diameter of starch grains in endosperic cells increases; or endosperic cells of the core don't die as the endosperic cells of the frings do.
