Abstract
The present studies were carried out to observe anatomical difference in the structure of the starch cell layer among normal, trash and white-core kernels of rice. The starch cells in normal grain might be divided into three different types in sharp and are able to be diagramed as Fig. 1. The structure of the starch cell layer developed in a trash grain was different from that in a normal kernel, especially, there existed remarkable differences among green, brasted and notchedbelly kernel. On the sections of a white-core kernel of rice, it was observed that in rectangular cell layer of starch cells there were two peculiar structures. One of them was a small crack and the other a slender line along the dorso-ventral diameter of the kernel. But the reason why they were turned out, was quite dark in this observation.
