Abstract: (31177 Views)
Effect of different exogenous putrescine concentrations on post-harvest life of strawberry, apricot, peach and sweet cherry fruit was separately studied using completely randomized designs in three replicates. Fruits were immerged in putrescine solutions (0.3, 0.5, 1 and 2 mM for 5 minutes in strawberries, and 0.5, 1, 2, 3 and 4 mM for 10 minutes in the other fruits) and also in distilled water as control. They were then transferred into the fridge. Post-harvest life of all fruits was increased by the use of putrescine. Ethylene production and water loss of the fruits were reduced by this compound. Putrescine also prevented softening of fruit's tissue during their storage period. Titratable acidity was reduced in untreated fruits while their pH was increased. These trends were also observed with the application of putrescine in all fruits, but at a much slower rate compared with the controls. Soluble solids content of sweet cherry fruits was increased by the use of putrescine while it was reduced in the other three fruits.
