Abstract

Background and Objectives: Salinity stress is the crucial factor that seriously limits agricultural production in various regions especially in arid and semi-arid areas. Nitric oxide is a bioactive molecule that synthesizes via enzymatic and non-enzymatic pathways under stress conditions in different organs of plant, regulates and adjustments defense reactions of plant. Sodium nitroprusside (SNP) is used as a releasing compound of Nitric oxide. Many studies have shown that this compound can protect plant under oxidative stresses and maintain chlorophyll. SNP could improve the effects of salinity and increased chlorophyll. Materials and Methods: This experiment was conducted at the plant tissue culture laboratory in Department of Horticultural Sciences, University of Tabriz, Iran, during spring– summer of 2017. This study was investigated the effect of sodium nitroprussdie as a Nitric oxide donor, on growth characters (leave number, plantlet height, fresh and dry weight), physiological (chlorophyll a, b and carotenoids) and biochemical (Antioxidant activity, total phenol, protein and Glycine betaine) characters of Solanum tuberosum cv. Agria under Salinity stress and in vitro condition. For treatment the single node of S. tuberosum cv. Agria stem were cultured in MS medium with ½ MS medium, four levels of sodium nitroprosside (0, 10-3, 10-4 and 10-5 mM) and two levels of salinity (0 and 70 mM). Treatments were factorial combinations of salinity as completely randomized design with 3 replications. Results: Obtained results showed that under Salinity stress leaves number, height and fresh and dry weight of plantlets decreased, also chlorophylls, carotenoids, protein and total phenol of plantlets showed significant reduction. In contrast, Antioxidant activity and Glycine betaine content of in vitro plantlets significantly increased. Application of sodium nitroprusside in media culture caused to improvement of growth, physiological and biochemical characters under Salinity stress. Conclusion: Antioxidant activity, total phenol and protein were decreased Salinity stress. In addition, Antioxidant activity and Glycine betaine content during salt stress period was decreased application of Nitric oxide. The Glycine betaine content of plantlets in general condition with application of sodium nitroprosside increased but under Salinity stress, sodium nitroprosside had negative effect on Glycine betaine content. The results of this research showed that with increasing Antioxidant activity, total phenol, protein can tolerate salt solution and also applying the SNP enhance plant tolerance to salinity. Further studies are necessary to determine optimum concentration and duration of NO application in order to achieve maximum benefit of this chemical in Solanum tuberosum tissue culture.
