Abstract
Influence of uniconazole (UNI) and benzylaminopurine CBA) on flowering and growth of Acalypha hispaniolae was evaluated. Drenches of UNI at 0.02, 0.1 and 0.2 mg ai per pot, and foliar application of 112, 225, or 450 mg BA/liter were applied 4 weeks after potting. UNI applied at 0.02 mg ai increased number of racemes produced 5 and 10 weeks after treatment, but did not influence shoot growth or stem length. At higher rates, UNI reduced flowering and growth. Application of 450 mg BA/liter increased number of racemes and shoot growth 5 weeks after treatment, but not 10 weeks after treatment. The best combination of rapid shoot growth, increased number of racemes, and increased size of racemes resulted from the interactive application of 0.02 mg ai UN1 per pot and 450 mg BA/liter. Better growth management might be obtained from a refinement of the concentration ranges studied.
