Analyzing the application frequencies of the growth regulators (once or twice a month), we found that at a frequency of once a month paclobutrazol produces the shortest plants. Treatment applied twice a month with CCC produced the shortest plants. In terms of growth regulator doses, the shortest plants were produced by dosing paclobutrazol at 20 mg L-1, followed by 10 and 5 mg L-1. The similar concentration dependent manner was found for CCC, plants were shortest at 6000 mg L-1, followed by doses of 4000 mg L-1 and 2000 mg L-1.
Comparing the two regulators, paclobutrazol produced the shortest plants.
