Effect of Salicylic acid, Potassium Silicate Fungal Elicitor under Conditions of Salinity Stress on the Evergreen Plant (Calendula officinalis L.)

In order to investigate the effect of salicylic acid, potassium silicate and fungal Elicitor in calendula under salinity stress conditions, a factorial arrangement in a randomized design with three levels of salinity (0-300600ppm) and 3 levels of salicylic acid, potassium silicate and fungal Elicitor (300-600-900 ppm) in 3 replicates. The highest amount ofH2O2was observed in potassium silicate treatment with a concentration of 300 ppm and a value of 68.87 nmol / g fresh weight. The highest amount of catalase enzyme in Salinity SA was obtained 600 ppm with a value of 0.0584 mg / d of protein per minute. The average number of leaves in potassium silicate treatment was higher than other treatments. The lowest root diameter in a substrate with 600 ppm salinity was observed at a concentration of 300 ppm in penicillium fungicidal oligoetherium with a value of 0.61 mM. In the concentration of 900 ppm in non-saline bed, the highest root diameter was observed with a value of 1. 08 mm
