Calcium (Ca2+) is an essential macronutrient in plants, and low concentrations of this nutrient may result in development of a physiological disorder known as blossom-end rot (BER) in tomato. Hormones can regulate the accumulation of Ca2+ and, consequently, fruit susceptibilities to BER. The objective of this study was to evaluate the effect of gibberellin (GA), abscisic acid (ABA), and 24-epibrassinolide (EBL) on Ca2+ accumulation and BER incidence in tomato. The ?Tyna c.v? tomato plants were sprayed biweekly, during anthesis, with water (control), GA (28.9 ?mol L-1), ABA (90.8 ?mol L-1and 136.2 ?mol L-1), EBL (0.01 ?mol L-1 and 0.1 ?mol L-1). Treatments were applied until the physiological maturity of fruits of the first raceme in a completely randomized design and then, the following evaluations were performed: percentage of BER, growth evaluations, Ca2+ contents, physicalchemical parameters in fruits, stomatal conductance and transpiration. ABA and EBL treatments reduced BER incidence in a range of 6.6 to 9.0 %. The bioregulators used had no effect on plant growth, fruit diameter, length, or color. However, application of GA and EBL reduced titratable acidity and, the first also reduced soluble solids content in the fruit. All treatments, except GA treatment, increased Ca2+ contents in the fruits, when compared with the control. The highest fruit Ca2+ content was observed in plants treated with 0.01 ?mol L-1 of EBL. According to our results, ABA and EBL increased Ca2+ concentrations and decreased BER incidence and thus there is a great potential for their use in agriculture in tomato fruit.
