ABSTRACT
Saline soil and water has a detrimental effect on agricultural production by reducing plant growth and yield. Much research has reported changing levels of physiological and biochemical parameters under salinity stress. The smoolits leave fill up more dissolved sugars of glucose, fructose and proline with salicylic acid. This determines that salicylic acid (SA) has a very important role in determining plant response to stress and many studies have reported on plant modification using salicylic acid to reduce the damage caused by saline soil and water. Tests were done to evaluate the effect of salicylic acid under various concentrations of salinity (0, 4, 8 and 12 dsm-1;) as a factorial experiment in a complete randomized design (CRD) with three replications. Salicylic acid applications (0, 0.5 and 1mM) were tested under greenhouse conditions to evaluate the effects on some physiological and biochemical characteristics of Brassica napus L. Results showed that increasing levels of NaCl reduced amounts of photosynthetic pigments (Chl a, b and carotenoids); protein and soluble sugars and free amino acids including proline and MDA compared to the control plants. SA application increased photosynthetic pigments (Chl a, b and carotenoids), protein and soluble sugars, free amino acids including proline and MAD content compared to plants under salinity stress.
