Abstract

The physiological responses of alfalfa (Medicago sativa L. cv. Gilboa) to salinity (100 mM NaCl) and some inorganic nutrients (K⁺, Ca²⁺ and N as NO₃^-) were investigated. Salinity caused a substantial reduction in biomass, carbon assimilation rate, stomatal conductance, water use efficiency, leaf area, relative growth rate, NO₃^- content and nitrate reductase activity, whereas, transpiration rate was slightly affected. Inclusion of K⁺, Ca²⁺ and N as NO₃^- in plant nutrient medium in combination or alone brought about a marked stimulation in control plants and moderated the salinity caused reductions in NaCl treated plants. In addition, plants also exhibited differences in these parameters at two growth stages.
