Physiological improvement for alleviation of salt stress tolerance in wheat

Author(s): Varsha Rani Choudhary
Abstract: Salinity is the dangerous constraints facing agriculture in present day. Some biological and chemical process is being pursued to cope with soil salinity. The issue of different pre-sowing seed operations (hydro priming, halo priming, ascorbate priming and pre-sowing chilling operations on seed germination, vigor, antioxidants and entirety soluble protein substance was investigated in 2 wheat (Triticum aestivum L.) Salt sensitive & salt tolerant are below saline (20 days m-1) or non-saline (6 days m-1) situation. All pretreatments of seeds, halo priming followed by hydro priming was the mainly powerful in alleviating the adverse outcomes of salinity by improving germination and seedling improvement of both cultivars. Salinity significantly improved leaf protein substance in both cultivars, but the magnitude of enhance in protein substance was greater in Auqab-2000 as compared to that in MH-97. Very pre-sowing seed operations significantly improved Superoxide dismutase movement in MH-97 as priming with CaCl2. 2H2O and as corbate were very capable in Auqab-2000 during stress situation. The tolerant of salt cultivar Auqab-2000 had a superior protection beside reactive oxygen kind as evidenced by increased Superoxide dismutase, substance, and catalase actions underneath salt stress. In conclusion, halo priming and hydro priming successfully improved the seed performance in both cultivars whereas priming with ascorbate was only effective in tolerance cultivar under salinesituation. This advantage was attributed to early and synchronized germination, vigorous stand establishment, and decreased oxidative broken due to improved antioxidant scheme.
