Light effects on plants

The response of 14 cultivars of Cyclamen persicum (Mill.) to growing temperatures of 13 and 17 C, and four holding temperatures was evaluated. Results indicated that a growing temperature of 17 C significantly reduced the time from seeding to flowering of the cultivars studied. The effects of growing temperature on flower production and shelf life varied among the cultivars tested. The shelf life of the cvs. Rose of Aalsmeer, White Carmel Eye, Cattleya, Cardinal, Rose of Marienthal and Pearl of Zehlendorf was increased by growing them at the higher temperature. Shorter shelf life was associated with higher holding temperatures, but the amount by which shelf life was reduced varied among the cultivars. These findings are expected to have a beneficial effect on the future of cyclamen as a major pot plant.
