| Abstract:
Five growth regulators were investigated: uniconazole, paclobutrazol, flurprimidol, chlormequat and daminozide. An index was developed to compare the compactness of the plants when treated by the growth regulators at different concentrations. Treatments of 45 ppm uniconazole and 8 ppm flurprimdidol resulted in plants within the ideal range of compactness on the index scale. The plants were harmonic and both treatments ensured a large production of flowers. The concentrations tested of paclobutrazol were all suboptimal. Daminozide did not have any good reducing qualities on Osteospermum. | |
