Abstract
Interaction between a progress of the kernel senescence and the transition in dehydrogenase activity in the spikelet tissue has been examined in a variety of rice plant (c. v., Koshijiwase). It was found in the rachilla that a disappearance of the enzyme activity with TTC reaction is the earlist at a part deserving of absciss layer in the pedicel of tissues, i. e., rachilla, husk, embryo, and endosperm. The proper and natural rout becames senile though the rachilla, empty glume, husk, vascular bundle of endosperm before occurring endosperm senescence in the spikelet tissue. Such a fact was found by a histo-chemical investigation. Therefore, there seems to be that to protect a senescence of the rachilla supporting a spikelet means to perfect the maturity.
