| Abstract: | Results of 8 years of trials have been used to assess the cold requirements of 116 tulip cultivars, expressed as the number of days of cold (9°C) required to produce flowers in 21 days at 18°C. The data are compared with commercial recommendations for the dates of transferring tulips to the glasshouse for forcing. |
