Although the contents of glutathione in potato tubers are quite low during their dormant period, by the natural termination of their dormancy the contents of the total and reduced form of glutathione in the various tissues of the tubers, especially in the apical buds increased. Similarly the contents of glutathione in the various tissues of potato tubers treated with MH also increased by the termination of their dormancy, but their increasing rates were much lower than that of the non-treated one, particularly considerable differences in contents being recognized in the apical buds. These facts tell us that the glutathione, particularly in the apical buds, may play some roles by the termination of dormancy of potato tubers. These facts may also support our previous assumption of attaching great importance of the apical buds of the potato tubers to their dormancy.
