Investigation of Salicylic Acid Application to Reduce Postharvest Losses in Stored ‘Bidaneh Ghermez’ Table Grapes

Four concentrations of salicylic acid (0, 1, 2, and 4 mM) were applied postharvest to ‘Bidaneh Ghermez’ grapes (Vitis vinifera); to investigate their potential impact on the fruit quality and storage life. They were stored for up to 45 days at 0°C, followed by 2 days at 20°C. The results indicated that postharvest treatment of grapes with salicylic acid could potentially improve berry and cluster appearance while significantly reducing fruit quality deterioration. Fruits treated with salicylic acid had greener and softer stems, and at the same time decay incidence was more efficiently controlled.
