ABSTRACT
The plant withstands the hot, dry conditions of the summer season environment as a leafless, dormant, corm-like organ at the soil surface. Commercial cyclamen have been genetically characterized as tetraploids and aneuploids, while basic species are diploids possessing chromosomes. The cyclamen has been a leading year-round pot plant in Europe for many years, and has been grown to a lesser extent in the US and other areas, especially for fall and winter sales. Greenhouse-grown plants required more leaves in winter than in summer for the appearance of the first generative buds. Light intensity appears to be a definite factor in initiating generative buds and transforming combined vegetative and generative meristems into generative ones. Nutrient levels influence cyclamen flowering to a limited extent.
