The experimental design was completely randomized, with four replications, evaluating five doses of the mixture of plant growth regulators, in the form of the commercial product Stimulate® (0, 50, 100, 150 and 200 mL p.c./100 L H2O). The spray applications of plant growth regulators started when the plants presented 7-8 expanded leaves, carried out fortnightly, totaling five applications along the cycle. The authors evaluated gas exchange measures; fresh mass, diameter and firmness of “heads”; and number of leaves. The study concluded that applications of 200 mL of the mixture of plant growth regulators p.c/100 L H2O promoted higher photosynthetic yield (21.40 µmol CO2/m2/s), and fresh mass (3.46 kg), vertical and horizontal diameter (13.23 and 16.61 cm), number of leaves (30.95) and firmness of the “head” (54.48 N). The authors recommend, in order to choose the best dose, to analyze to which market segment the product will be directed.
