EFFECT OF SALİCYLİC ACİD PRETREATMENTS ON SEEDLİNG GROWTH AND ANTİOXİDANT ENZYME ACTİVİTİES OF SUNFLOWER (HELİANTHUS ANNUUS L.) AND LİNSEED (LİNUM USİTATİSSİMUM L.) PLANTS UNDER SA

Abstract
Salinity has become a problem all over the world in agricultural areas. Plants develop self defence mechanisms to resist salt stress by increasing various antioxidant enzyme activities. The effects of stress could be reduced with various treatments including salicylic acid (SA) and its effects vary depending on the plant species and cultivars. This study sunflower and linseed seeds were primed for 4 hours with 0 (control treatment - SA1), 0.25 mM (SA2), 0.50 mM (SA3), 1.00 mM (SA4) priming then the seeds were to develop in petri dish with different salt concentrations 0(control)(S1), 50mM(S2), 100mM(S3), 150mM(S4) concentrations for 14 days. It was noted that salicylic acid had a positive effect on both morphological and chemical properties in both plant species grown under salt stress.
