【 摘 要 】

With the purpose of implementing a practice that helps to improve strawberry production in low-yield areas, the use of growth regulators, which may influence the postharvest behavior of fruits, was evaluated. Strawberry plants (cv. Albion) received applications of the following regulators: a) GA3, b) Mixture of GA4+GA7+6BAP, and c) 6BAP. The products were sprayed at doses of 300, 600 and 900 mg·L-1, plus a control in a factorial arrangement of treatments, and were evaluated by a completely randomized design with four replications. Determinations made at the harvest time indicated that, on average, all regulators produced increments in strawberry production, and this increase was linked to increased fruit size. Only GA4+GA7+6 BAP affected the red color with respect to the control, and there was no other definite effect on fruit quality, due to the fact that the acidity was not affected, while TSS and firmness had fluctuating responses. It is concluded that regulators, in the average of their doses, were able to increase the fruit size and production, but no effect on the organoleptic quality was detected.
