• The spectral dependence of Begonia evansiana in supplementary light periods of photoperiodic tuberization and sprouting was investigated. Supplementary application of red light inhibited tuber development, thereby stimulating vegetative growth. Supplementary blue or far-red light also suppressed tuber development, but barely stimulated vegetative growth. However, both red and blue light, given at 6℃ during the main light period or the supplementary light period, permitted the tuberization under the subsequently given conditions of either long-days or darkness at 23℃. Blue light applied after 5-days of irradiation with white light at 10℃, showed almost the same action as far-red light, which suppressed tuberization in darkness. The nature and function of the pigments concerned in the photoperiodic responses are discussed.
