Cobalto associado com fosfito de potássio melhoram a qualidade pós-colheita da manga cv. Palmer

Abstract

Mango is a highly perishable fruit due to its climacteric nature, reducing its Post-harvest period. Thus, in order to extend the useful life of the mango, the fruits were treated in the pre-harvest with potassium phosphate solution (1.4 g/mLKH2PO4) and control solution (0 g/mLKH2PO), associated with different doses (0; 48; 64; 80; 112 mL. plail) of cobalt at a density of 1.30 g/mL. Physical, chemical and biochemical triables were measured. The use of cobalt and potassium phosphate favored the maintenance of color and firmness, reducing the respiratory rate. Since the treatments significantly affected the chemical variables, reducing the content of soluble solids, conserving ascorbic acid, maintaining pH. The foliar application of Cobalt and Potassium Phosphate in the pre-harvest is an efficient technique for improving the useful life and maintaining the quality of the mango during storage at room temperature.
