Abstract

To study the interaction effect of the salinity and salicylic acid on some morphological and physiological traits in clary sage (Salvia sclarea), a pot experiment was conducted as factorial based on a completely randomized design with three levels of NaCl and control (zero, 50, 100 and 150 mM), as the first factor and three levels of spraying the solution of salicylic acid and control (zero, 100, 200 and 300 mg/L), as the second factor with three replications in the greenhouse of Semnan Jihad-e-Agriculture Education center in 2013.The results of data variance analysis showed that the interaction of the salinity stress and salicylic acid levels were significant in other traits except the leaf length fresh weight and the rate of carotenoids. The maximum effect was seen at the salinity level of 50 and 100 mM and salicylic acid application at 200 mg/l. The results of this study indicated that leaf area and number, petiole length, leaf length and width, leaf fresh and dry weight, root length, chlorophylls concentration were influenced by the salinity levels in this plant. Somehow, their rates were decreased by increasing the salinity level, whereas the rates of soluble sugar, proline and carotenoid were increased. The application of salicylic acid showed a reducing effect in all traits.
