Abstract
Four cultivars of Aquilegia flabalata and four cultivars of Aquilegia× hybrida were cooled 0, 4, 8, or 12 weeks and forced in either long-day (LD) or short-day (SD) photoperiods. Cultivars of both species cooled eight or 12 weeks flowered in fewer forcing days than non-cooled plants, however, days to flower were similar for LD and SD photoperiods regardless of cooling level. Flower stem length increased with increasing cooling duration, and flowering stems were longer in LD photoperiod than in SD. Plants cooled eight or 12 weeks were either larger than or similar in size at flowering to non-cooled plants or those cooled four weeks. In this study, eight weeks cooling and LD photoperiod enhanced forcing phase growth and flowering of the columbine cultivars most efficiently.
