Studies on Morphogenesis in Rice Plants. : 3. Interrelation of the growth among leaves, panicle and internodes, and a histological observation on the meristem of culm.

As the result of an observation on the elongating process of leaf blade, leaf sheath, panicle and internode in all over the growing period of rice plant, a regularity of development was recognized among those organs, and a problem was proposed that the regularity is due to the constitution of vascular bundles and its ripenning process in the culm. By the way, the meristem concerning with the culm formation were studied by histological methods, with special reference to the intercalary meristem of internode.
