| Abstract | ||||
| The experiment was carried out during the two successive seasons (2016 and 2017) on two new grape varieties ARRA 15 and ARRA 18 cultivated in sandy soil at Sadat city, Menoufia governorate, Egypt to study the effect of sprayed potassium silicate as preharvest with modified air packaging (MAP) on; postharvest quality, storage and marketing abilities, and control of postharvest diseases of grape fruits. Results showed that potassium silicate or modified air packaging separately or joined has leads to improvement the maintenance of all quality, storage and marketing abilities, and control of postharvest diseases of grape fruits during the total storage period (5 weeks) when compared to non-treated fruits, which showed loss of all studied properties after only 3 weeks of storage under cold storage. Out of the present study (results), it could be recommended to apply both; spraying with potassium silicate along with modified air packaging to maintenance grape quality storage and marketing abilities, and reducing of postharvest diseases. | ||||
