چکیده The current study was conducted to elucidate the effect of gum ghatti (GG; 1% w/v), putrescine (Put; 100 μM), and a combination of both on maintaining postharvest quality of "Golden Drop" plum fruits during 40 days of storage at 1°C factorially (4×4) based on completely randomized design with three replicates. The results showed that Put and GG, alone or in combination, help protect plum fruit cell membranes during postharvest storage. Plum fruits coated with Put + GG showed significantly reduced weight loss, softening and electrolyte leakage, hydrogen peroxide and malondialdehyde production. During storage, TA decreased, associated to an increase in pH, and TSS increased In conclusion, Put and GG coatings are recommended to maintain the quality of ‘Golden Drop’ plums during post-harvest cold storage.
