Abstract
Floral induction of broccoli (Brassica oleracea italica) ‘Waltham 29’ at low temp (5°C) was associated with increasing levels of starch and sugar in the shoot tip. This same relationship was found in experiments concerning plant age, duration of cold treatment, leaf removal before and during cold treatment, and treatment with succinic acid 2,2-dimethylhydrazide (SADH) or gibberellic acid (GA3).
Greenhouse experiments with plants grown continuously at 16-21°C or 21-27°C indicated that high carbohydrate levels are not necessarily associated with flowering. Flowering was delayed at the higher temp with little difference in carbohydrate level.
