Exogenic Function of Salicylic Acid to Promote Saline Tolerance in Cucumber

Two local varieties of cucumber (summer green and super green special) were grown-up in pots under 3 dSm -1 NaCl salinity levels. The study of CRD design containing 4 replications in pots was performed. Half strength (0.5) Hoagland's nutrient in the form of solution was implemented to plants for improved nourishment and at 3 to 4 leaf phase (SA) salicylic acid was sprayed with 5 different concentrations (0.5 mM, 1.0 mM, 1.5 mM, 2.0 mM 2.5 mM) and were compared with control. Data regarding to various morpho-physiological and biochemical attributes like germination (%), mortality (%), root length (cm), shoot length (cm), no. of leaves, (TFW) total fresh weight (g), (TDW) total dry weight (g), nitrogen (N) concentration (mg g -1 DW), phosphorous (P + ) concentration (mg g -1 DW), potassium (K + ) concentrations (mg g -1 DW), Chlorophyll Contents Index (CCI) and (PC) protein contents (mg) was studied. Results revealed that maximum germination, Total Fresh Weight (TFW) (g), Total Dry Weight (TDW), Chlorophyll Contents Index (CCI), nitrogen contents, phosphorous contents, potassium, protein contents and minimum mortality was obtained by the exogenic appliance of (1.0 mM) SA (Salicylic Acid) in summer green variety relatively to other treatments and variety.
