| Abstract | ||||
| The present study was carried out during the two successive seasons (2014 and 2015) to investigate effectiveness of some resistance inducer compounds on Quality and Control of Postharvest Diseases of Zibda mango fruits under different storage periods. Culciven compound were applied spraying on mango trees at 3 times before harvesting. Mango fruits were harvested at maturity stage then were divided into groups, each group was dipping in one of following materials: Salicylic acid at concentration of 1 and 2 gL-1, Potassium Sorbate concentration of 2 and 3 gL-1) and tape water for 3 minutes and were stored at 10°C and 85-90%RH. Samples of fruits were taken weekly during storage periods, to determent weight loss, fruit firmness, fruit decay% and fruit color as well as total acidity, total soluble solids, total sugars and vitamin C content. The obtained results indicated that the mango trees sprayed with Culciven recorded the best values for all tested fruits parameters as compared to untreated (control). Application of both Salicylic acid and Potassium Sorbate at different concentration supported fruit quality properties. Potassium Sorbate 3gL-1 recorded the higher positive values of weight loss, fruit firmness, fruit decay%, fruit color, total acidity, total soluble solids, total sugars and vitamin C content as compared to concentration 2gL-1.In contrary, applying Salicylic acid at lower concentration (1gL-1) was the supporter as compared to higher concentration (2gL-1). Moreover, Salicylic acid applied at 1gL-1 concentration gave the best fruit quality as compared to other tested treatments during different storage periods. | ||||
