Abstract
Saline soils supporting Salvadora persica near Bhavnagar, Gujarat, showed variation in pH from 7.9 to 8.2 and salinity fluctuated from 9.39 to 54.37 ds/m. Leaves and stems contained 93-161 mg/g alkali soluble proteins, and amounts of other proteins varied from 56 to 102 mg/g. Alanine, asparagine, aspartic acid, glutamic acid, glutamine, methionine, phenylalanine, serine, threonine, tyrosine, and valine constituted the major fraction of free amino acids and accumulation of these 11 amino acids was maximum in summer. Na+, Cl-, K+, Mg2+ and Casuperscript 2 were the principal inorganic constituents of leaves and stems.
