Abstract
Previously, separated sprays of 1.6 mM resveratrol (RVS) and 1.0 mM 6-benzylaminopurine (BAP) before harvest of cherimoya fruit (Annona cherimola Mill.) reduced the postharvest rate of pulp and peel softening, and the loss of peel color, respectively. Aim of present research was to reduce both, postharvest fruit softening and peel color loss in cherimoya ‘Ruth’ and ‘Fino de Jete’ by applying a mixing solution of 1.6 mM resveratrol and 1.0 mM benzylaminopurine at 8 or 15 days before harvest. After fifteen days stored at room temperature, the color parameter L*, indicating the darkening of the fruit peel, was reduced up to 41% for ‘Ruth’ and 58% for ‘Fino de Jete’ by RVS and BAP sprays. RVS and BAP reduced fruit and peel softening in ‘Ruth’; but higher effect, i.e. over 100 N and 60 N in relation to control at 7 days in storage, was observed in ‘Fino de Jete’ fruit and peel, respectively. The higher enzymatic activity of polygalacturonase (PG), possible inducing fruit and peel softening, was retarded for two days in RVS-BAP treated fruit in relation to control.
