In order to enlarge the shipment period of Tricyrtis macranthopsis Masam., regulations of flowering time by photoperiodic treatment were studied. 1. Flowering time became slow for 36-days from in control by 16-hrs photoperiodic treatment from September 1th to flowering time. 2. Effective light intensity was more than 501x. 3. Flowering time became early for 28-days from in control by 8-hrs photoperiodic treatment from August 1th to flowering time. 4. The time of flower bud differentiation was guessed with the beginning of August from the end of July. 5. Under natural photoperiod, the growth of stems almost stopped by the end of June. 6. Photoperiodic treatments did not influence the number and size of flowers.
