Silicon (Si) is the most abundant element on earth after oxygen and very important for plant growth under stress conditions. In present study, we inspected role of Si in mitigation negative effect salt at three concentrations (40 mM, 80 120 mM NaCl) two wheat varieties (KRL-210 WH-1105) with or without (0 2 mM) treatment. Our results showed that photosynthetic pigments, chlorophyll stability index, relative water content, protein carbohydrate content were reduced all both varieties. Moreover, lipid peroxidation, proline phenol electrolyte leakage significantly increased salinity stress. The antioxidant enzyme activities, like catalase peroxidase, enhanced leaves roots; however, SOD activity was drastically decreased roots. These effects more pronounced WH-1105, as KRL-210 a salt-tolerant variety. On other hand, supplementation improved water, protein, contents addition, MDA shown to decline following application It found applying activities better WH-1105 than KRL-210. Furthermore, be effective concentration compared low mM), indicating it stressed experimental findings will open new area research identification implication novel genes involved enhancing tolerance.

Climate change, expanding soil salinization, and the developing shortages of freshwater have negatively affected crop production around world. Seawater salinized lands represent potentially cultivable areas for edible salt-tolerant plants. In present study, effect salinity stress on plant growth, mineral composition (macro-and micro-nutrients), antioxidant activity in dune spinach (Tetragonia decumbens) were evaluated. The treatments consisted three salt concentrations, 50, 100, 200 mM, produced by adding NaCl to nutrient solution. control treatment had no but was sustained irrigated Results revealed a significant increase total yield, branch production, ferric reducing power plants with solution incorporated 50 mM NaCl. Conversely, an increased level (200 mM) caused decrease chlorophyll content (SPAD), while phenolic content, as well nitrogen, phosphorus, sodium, increased. results this study indicate that there is potential brackish water cultivation consumption, especially provinces experiencing adverse drought salinity, where seawater or underground saline could be diluted used irrigation vegetable.
