Abstract: | The course of development of mitochondrial activities was studiedin the early stage of germination of Phaseolus mungo seeds.Mitochondrial activities (state 3 oxygen uptake rate, respiratorycontrol, and ADP/O values) increased, while the activities ofglycolytic enzymes (aldolase, glyceraldehyde-3-phosphate dehydrogenase,and pyruvate kinase) hardly changed, during the early periodof imbibition. The activities of mitochondrial enzymes (malateand succinate dehydrogenases, and cytochrome oxidase) increasedduring the period, but the rates were still low compared withthose of glycolytic enzymes. On the basis of these results,a significant difference in activation patterns between glycolyticand mitochondrial activities is discussed. |
