Effect of Antioxidants and Salinity Stress on Seedling Parameters of Some Wheat Cultivars

Abstract:
Background and Objectives: Salinity is one of the major problems inhibiting early establishments of seedling. To check the impact of antioxidants on early seedling growth of some bread of wheat cultivars under salinity stress. Current investigation aimed to study the influence of antioxidants seed prim of some bread wheat cultivars to germinate under salinity concentrations on seedling parameters. Materials and Methods: A laboratory experiment was conducted in the Agronomy Department seed lab, Faculty of Agriculture Mansoura University, Egypt during November and December 2016. A factorial experiment assigned to Randomized Complete Block Design in four replication used. Four bread wheat cultivars i.e., Miser-1, Miser-2 and Gemmiza-12, three types of antioxidants, Salicylic acid, Ascorbic acid and Humic acid and three concentrations of antioxidants 0, 100 and 200 ppm under salinity levels of 0, 40, 80, 120 and 160 Mm. Results: The length of shoot and root, fresh and dry weight of shoot and root, seedling vigor index, total chlorophylls and germination tolerance index significantly affected by studying wheat cultivars. The tallest shoot and root as well as highest weight of fresh shoot, the highest values of seedling vigor index, the highest values of total chlorophylls and the highest values of germination tolerance index was obtained from Misr-1 cultivar. Soaking in humic acid as pretreatment significantly increased root length, fresh weight of shoot and root and seedling vigor index. Whereas, soaking in Ascorbic acid as pretreatment recorded the tallest shoot, root dry weight, total chlorophylls content and germination tolerance index. The results also designated that all these parameters were increased from increasing antioxidants concentrations until 200 ppm. Increasing salinity concentration from 40-160 mm significantly abridged the length, weight of fresh and dry shoot and root, seedling vigor index, total chlorophylls and germination tolerance index. Conclusion: In general, it could be concluded that priming bread wheat seed with Ascorbic acid or Humic acid as at concentrations of 200 ppm of Misr 1 or Gemmiza 12 cultivars enhanced seedling establishment under salinity stress (40 mM NaCl) to cultivate bread wheat under new reclaimed saline soil in Egypt.
