Studies on year-round flower production in pot chrysanthemum

The effect of controlled photoperiod and growth retardants on duration of flowering and flower size of cultivars Áparajita'and 'Ragini'of chrysanthemum (Dendranthema x grandiflorum (Ramat)) during different times of the year has been described. MH (200 ppm) proved to be the most effective in increasing duration of flowering and flower size over control. This was followed by MH 1000 ppm. The effect of CCC was not consistent during different times of the year. Further, in comparison to natural photoperiod, controlled photoperiod was found better for increasing the duration of flowering in August planting.
