Abstract
AN experiment trial was carried out during 2017 and 2018 seasons on Wonderful pomegranate trees about 7 years old grown in sandy soil under drip irrigation system from well at private orchard located on Cairo-Alexandria desert road (about 50 km from Cairo), Egypt. Treatments of salicylic acid (50,100 and 150 ppm), ascorbic acid (500, 750 and 1000 ppm) and tap water control were foliar sprayed twice a year i.e. at full bloom and four weeks later. Abstractly, salicylic and ascorbic acid treatments enhanced leaf characteristics, yield and fruit quality traits as well as minimized sunburned and cracked fruit percentages. Ascorbic acid treatment at 1000 ppm proved to be most efficient treatment in this respect.

Means within each column followed by the same letter (s) are not significantly different at 5% levelThe enhancement effect of salicylic acid on leaf characteristics of pomegranate trees may be attributed that salicylic is a growth regulator which participates in the regulation of physiological processes in plants
Salicylic acid has a role in protecting the cells from senescence and preventing free radicals from the oxidation of lipids the components of the plasma membrane
Summary
Table 2:- Chemical analysis of water used for irrigation in 2017 and 2018 seasons. E.C. The experiment consisted of forty two trees healthy, nearly uniform in shape and size and productivity and received the same horticulture practices, were subjected to seven treatments as: control tap water, Salicylic acid as foliar sprays at 50 ppm, Salicylic acid as foliar sprays at 100 ppm, Salicylic acid as foliar sprays at 150 ppm, Ascorbic acid as foliar sprays at 500 ppm, Ascorbic acid as foliar sprays at 750 ppm, Ascorbic acid as foliar sprays at 1000 ppm. Spraying was carried out using compression sprayers (5L solution/tree) at the previously mentioned dates. Foliar spray of salicylic and ascorbic treatments were carried out at two times, the first foliar spray was done at full bloom and the second one was performed four weeks later, the control trees were sprayed with tap water at the previously mentioned times. Cracked, sunburned fruits Number of cracked and sunburned fruits per tree was counted and recorded. The percentages of cracked and sunburned fruits/tree were calculated
