Two treatments for improving peach color (cv. Swelling) were tried at El Mama Farm (Cairo — Alex. desert road) in two successive seasons 2002 and 2003. Aluminum foil of 1 x 1 meter was spread on the ground under some trees and activated Jasmine oil (0.05 %) was sprayed on the others, in the first week of May. First sample was taken before treating the trees, and the second one was taken at the proper picking date in last May. Fruits were stored for one month. Physical and chemical quality parameters were estimated by the end of cold storage duration. The color Hue angle, fruit firmness, organoleptic tests, decay incidences, T.S.S., acidity percentages and anthocyanin content were estimated. The results revealed that aluminum foil caused a dear increase in peach fruit red color intensity Hue angle (43.0 and 39.0 in both seasons, compared to control 80.7 and 50.7 in both seasons respectively) and enhanced ripening, therefore it was indicated that fruits treated by using aluminum foil were softer (0.66 tb/Inch²) than control fruits, on the other hand, fruits of Jasmine oil treatment had the highest firmness by the end of the storage period (3.3 Lb/indr²) as compared to the control (1.76 Lb/inch⁼). Foil treated fruits had the highest anthocyanin values (7.067 and 10.67 mg/g in both seasons) than control (2.6 and 2.8 mg/g) whereas Jasmine oil treated fruits showed lower increase In anthocyanin content. T.S.S. % in aluminum foil treated fruits gave significant results as compared to control fruits whereas; Jasmine oil treatment caused a noticeable lower increase in T.S.S. %. It is recommended to use aluminum foil sheets under trees to enhance peach fruit color and accelerate the ripening rate, also applying Jasmine oil for improved fruit color and delayed ripening.
