The effects of growth retardants succinic acid 2,2-dimethylhydrazide (SADH), (2-chloroethyl) trimethylammonium chloride (CCC) and 2,4-dichlorobenzy 1-tributylphosphonim chloride (CBBP) on growth and flowering of Brassica oleracea var. italica, cv. ‘Waltham 29’ (broccoli) were investigated. All 3 compounds reduced plant height. At higher concn SADH reduced the no. of plants flowering in both cold and non-cold treated plants. Neither floral induction nor leaf no. was significantly affected by CBBP or CCC. Leaf no. increased with increasing conc of SADH, as a probable result of the increased inhibition of floral initiation.
