Certain Aspects of Control Mechanism of Stored Foods Degradation during Seed Germination

並列摘要


The control mechanism of stored foods degradation during seed germination was studied. When one excised cotyledon was incubated with three embryonic axes, it was found that the embryonic axis may stimulate the proteinase activity, RNA synthesis, and reserve protein breakdown in the excised cotyledons. Cytokinins may replace the embryonic axis function and stimulate the proteinase activity and RNA synthesis in the excised cotyledous. It is evident that the soybean cotyledon contains more than one proteolytic enzyme. The experimental results show that the embryonic axis may affect de kovo synthesis of the peak b component of the proteolytic enzyme.A possible explanation for these results is that the synthesis of proteolytic enzyme in the cotyledons of soybean seedlings is controlled by the embryonic axis and the hormone involed appears to be a cytokinin.
