Ornamental pepper submitted to treatments with daminozide in pots containing coconut fiber or sand
The demand for ornamental pepper as “potted plants” is growing. It is possible to produce these plants with growth regulators in substrates easily acquired and capable of providing high quality plants at low cost. The present study had the goal of evaluating the effect of applications of levels of t...

The present study had the goal of evaluating the effect of applications of levels of the regulator daminozide on ornamental pepper grown in pots containing coconut fiber (FC) or sand as substrates. A completely randomized design was employed in a 2x5 factorial scheme consisting of two types of substrate (FC and sand) and five levels of daminozide (0, 2, 4, 6 and 8 g L-1) applied three times during the experiment, at 25, 40, and 55 days after sowing.

The demand for ornamental pepper as “potted plants” is growing. It is possible to produce these plants with growth regulators in substrates easily acquired and capable of providing high quality plants at low cost. The present study had the goal of evaluating the effect of applications of levels of the regulator daminozide on ornamental pepper grown in pots containing coconut fiber (FC) or sand as substrates. A completely randomized design was employed in a 2x5 factorial scheme consisting of two types of substrate (FC and sand) and five levels of daminozide (0, 2, 4, 6 and 8 g L-1) applied three times during the experiment, at 25, 40, and 55 days after sowing.
