Abstract
An experiment was conducted to study the effect of seven treatments includes: GA3 50 and 100 mg/l , Salicylic acid(SA) 0.5 and 1 mM, Ascorbic acid(AsA) 50 and 100 mg/l in addition to the control distilled water , and three methods of applications (soaking of seeds, foliar, soaking + foliar) in some elements content of leaves plant in saline soil for the 2011-2012 growth season. The experiment was done according to complete randomized block design with three replications in Al-kefel area. The results were summarized as follow: GA3 and SA treatments in both concentrations caused a reduction in the leaves content of sodium and chloride significantly. SA, 1 mM treatment was superior. Soaking + foliar treatment had a significant effect in reducing leaf content of sodium and chloride as compared to other methods. GA3 and SA treatments in both concentrations and 100 mg/l AsA treatments caused higher calcium content. GA3 100 mg/l was superior. Soaking + foliar led to increase calcium content significantly as compared to soaking only. All treatments ( except 50 mg/l AsA) led to significant increase in leaf potassium content as compared to water treatment. The interaction between concentrations and methods of treatment had a significant effect in all traits.
