Resumo

The effects of three paclobutrazol (PBZ) application methods on ornamental characteristics of two pepper cultivars (‘Biquinho Vermelha’ and ‘Bode Amarela’) were evaluated. Plant growth regulator at 10 μM PBZ was added at transplanting by drenching 250 mL PBZ solution on the pot substrate, foliar spray of 10 mL PBZ solution or by submerging seedlings root + substrate for 10 seconds in the PBZ solution. Control plants were treated with tap water applied directly on the substrate. Plant height, canopy compactness, fruits and leaves number, and leaf chlorophyll content were evaluated when 50% of the plants had approximately 30% of mature fruits (commercial maturity). PBZ applied by drenching influenced positively the ornamental characteristics of ‘Bode Amarela’. Otherwise, the best PBZ application method for ‘Biquinho Vermelha’ was not established. The results suggest that search for suitable PBZ application method that no affects the pepper ornamental characteristics must be done specifically for each pepper cultivar.
