Rooted cuttings of Cuphea ignea A.DC. were planted into 8 cm pots containing a medium composed of 3 parts high moor peat : 1 clay : 1 perlite (v:v:v). Flurprimidol was applied once as a single foliar spray (0, 5, 10, 15, and 20 mg l-1) or a medium drench [0.0375, 0.075, 0.1125, and 0.1500 mg/pot (0.2 dcm3 of medium)]. Growth retardant was applied following second pinching, when shoots were 0.5-2 cm long. Well retarded plants were obtained when cuphea was sprayed with 5-10 mg l-1 of flurprimidol and drenched with growth retardant at 0.0375-0.075 mg/pot. Flurprimidol had a significant effect on the canopy diameter and the size of leaves and calyx-tubes of cuphea. The growth retardant treated plants had darker green foliage than the control ones. The chemical name used: a-(1-methylethyl)-a-[4-(trifluoromethyloxy)-phenyl]-5-pyrimidine-methanol (flurprimidol).
