【 摘 要 】

To investigate the effects of salicylic acid dipping and Aloe vera gel coating on shelf life and post harvest quality of table grapes (Vitis vinifera) of the cultivar Shahroudi, a factorial experiment was conducted on the basis of randomized complete blocks design with three factors and three replicates in agricultural faculty of Islamic Azad University in 2014. The treatments were dipping in Salicylic acid (three levels of 0, 1 and 2 mmmol-1 for 15 minutes) and coating with Aloe vera gel (four levels of 0, 10%, 15% and 20% w/v) and measurement of traits in 1st day, 30th day and 60th day after treatment of berries. The results showed that the interaction effect of salicylic acid and Aloe vera gel application was significant on all of traits except for pH value in a way that the best and the minimum weight loss (0.09g) was obtained by application of 2 mmol-1 Salicylic acid and 20% Aloe vera gel in 1st day after treatment. The greatest amount of total soluble solids (428.43 g.100g-1 fruit juice) was found in 2 mmol-1 Salicylic acid and 15% Aloe vera gel in 60th day. The highest Catalase enzyme activity (0.0013 Ua.mg-1Pro) was attained in 2 mmol-1 Salicylic acid and 15% Aloe vera gel in 30th day. These results demonstrated that treatment of grape berries by salicylic acid and Aloe vera gel had positive effect on shelf life of table grapes and their postharvest quality
