To clarify the change of the respiration in mulberry bud during the winter season, the oxygen up-take rate and the activity of dehydrogenase in bud were measured using Warburg's manometric method and tetrazolium test. Experiments were conducted during two winter seasons from 1961 to 1963. Results were summarized as follows:
1) The oxygen up-take rate was relatively high in the end of autumn, and then slowly decreased from early winter to mid-winter, but it was high in early spring again.
2) The parallelism between oxygen up-take rate and water content was seen in both cases measured immediately after harvesting and after storage on different desiccating agents.
3) The activity of dehydrogenase was relatively low in the end of autumn, but it was high since the first decade of December.
4) When the activity of dehydrogenase was high, the sprouting of bud was satisfactory. This fact showed that the dormancy was released.
