Influence of Temperatures during Long-night Exposures on Growth and Flowering of ‘Mace’, ‘Thor’, and ‘Telstar’ Kalanchoe1

Year: 1977

Type: article

Abstract: Kalanchoe × sp. cvs. Mace, Thor, and Telstar were subjected to 2, 3, 4, or 5 weeks of long nights (LN) at 10, 16, or 21°C. The cultivars varied in the number of LN for 100% flowering, and this was influenced by temperature. No temperature was more inductive than 16°C; yet, ‘Thor’ required twice as many LN as ‘Mace’. After 2 weeks of LN the relative growth-rate patterns among ‘Mace’ plants under non-inductive conditions continued, but the patterns of ‘Thor’ and ‘Telstar’ changed. Flowering after 2 weeks of LN averaged 91.7% for ‘Mace’, nil for ‘Thor’, and 25.3% for ‘Telstar’.
