Effect of GA3, salicylic and ascorbic acid concentrations and application methods on some minerals leaf contents of broad bean (Vicia faba L.)grown under salinity soil

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.
