When the results for each dose of paclobutrazol at each application frequency (once or twice a month) are compared, there is little difference between them: paclobutrazol at 5 mg L-1 produced plant heights of 31,04 to 26.71 cm; 10 mg L-1 produced plant heights of 20.55 to 23.87 cm; and 20 mg L-1 produced plant heights of 18.30 to 21.92 cm. Comparing CCC for each dose applied and at each application frequency (once or twice a month), it can be seen that 2000 mg L-1 for both application frequencies produced plant heights of 53.22 to 50.38 cm; 4000 mg L-1 applied once a month CCC produced plant heights of 47.36 cm, which did not differ from the control (58.93 cm).
