• 1. Seed germination of Begonia Evansiana ANDR. was investigated at 29℃. 2. The germination was induced under long-day conditions, the critical daylength being about 8 hours. Exposure to at least 2 or 3 cycles of long days was necessary for germination. The seeds could germinate under otherwise non-inductive photoperiods, when the dark period was interrupted with a short period of illumination. Thus the photoperiodic behaviour of Begonia seeds in germination is similar to that of typical long-day plants in flowering. 3. The application of gibberellin brought about no germination in complete darkness, but markedly reduced the critical daylength for germination, even 1-minute photoperiods being inductive. The germination under continuous light was also favoured by gibberellin application. The action of gibberellin in germination of Begonia seeds may be to intensify the light action or to substitute for a part of it.
