Abstract: We investigated the effects of end-of-day FR light irradiation (EOD-FR) on flowering in chrysanthemum. EOD-FR treatment in the low-temperature period promoted flowering in the autumn-flowering chrysanthemum cultivar ‘Jimba’. EOD-FR treatment with season flowering cultivation in autumn-flowering chrysanthemum promoted flowering in 14 out of 20 cultivars. EOD-FR treatment promoted flowering in short-day cultivation from the time of planting in 11 out of 20 cultivars of autumn-flowering chrysanthemum. EOD-FR treatment of summer-autumn-flowering chrysanthemum in the June-flowering cropping type promoted flowering in 19 out of 30 cultivars. EOD-FR treatment weakly promoted flowering near the critical night length in the autumn-flowering chrysanthemum cultivar ‘Jimba’; however, EOD-FR showed no effect on the duration of Dusk-NBmax of the chrysanthemum cultivar ‘Jimba’. The results of this study show that EOD-FR promotes flowering as well as internode elongation in chrysanthemum depending on the growing conditions.
