“…2 ). This increase in plant growth could attribute with the physiological processes including nutrient uptake, photosynthesis and increasing antioxidant activities as suggested by ( Alhasnawi et al, 2015 ). Our results also showed that the negative impact of soil salinity can overcome by the foliar application of AsA and can increase photosynthetic pigments ( Fig.…”

Barley ( Hordeum vulgare L.) is a major cereal grain and is known as a halophyte (a halophyte is a salt-tolerant plant that grows in soil or waters of high salinity). We therefore conducted a pot experiment to explore plant growth and biomass, photosynthetic pigments, gas exchange attributes, stomatal properties, oxidative stress and antioxidant response and their associated gene expression and absorption of ions in H. Vulgare . The soil used for this analysis was artificially spiked at different salinity concentrations (0, 50, 100 and 150 mM) and different levels of ascorbic acid (AsA) were supplied to plants (0, 30 and 60 mM) shortly after germination of the seed. The results of the present study showed that plant growth and biomass, photosynthetic pigments, gas exchange parameters, stomatal properties and ion uptake were significantly ( p < 0.05) reduced by salinity stress, whereas oxidative stress was induced in plants by generating the concentration of reactive oxygen species (ROS) in plant cells/tissues compared to plants grown in the control treatment. Initially, the activity of antioxidant enzymes and relative gene expression increased to a saline level of 100 mM, and then decreased significantly ( P < 0.05) by increasing the saline level (150 mM) in the soil compared to plants grown at 0 mM of salinity. We also elucidated that negative impact of salt stress in H. vulgare plants can overcome by the exogenous application of AsA, which not only increased morpho-physiological traits but decreased oxidative stress in the plants by increasing activities of enzymatic antioxidants. We have also explained the negative effect of salt stress on H. vulgare can decrease by exogenous application of AsA, which not only improved morpho-physiological characteristics, ions accumulation in the roots and shoots of the plants, but decreased oxidative stress in plants by increasing antioxidant compounds (enzymatic and non-enzymatic). Taken together, recognizing AsA's role in nutrient uptake introduces new possibilities for agricultural use of this compound and provides a valuable basis for improving plant tolerance and adaptability to potential salinity stress adjustment.

“…In the present study, the combination of Cr(VI) and MEL further enhanced the polyphenol contents. It has been previously reported that antioxidants produced within plants reduce the effects of stresses in plants [58,59]. Those polyphenols possess the affinity to bind with metal ions and thereby inhibit the production of several ROS and some of them sequester the heavy metals entering the cell [60].…”

In the current investigation, we studied role of Rhododendron leaf extract in Vigna radiata grown under chromium metal stress. We observed that seed treatment with Rhododendron leaf extract resulted in the recuperation of seedling growth under chromium toxicity. Seed treatment with Rhododendron leaf extract significantly improved the contents of anthocyanin and xanthophyll pigments under stress. The antioxidative defense system triggered after Rhododendron extract treatment, resulting in the increased actions of antioxidant enzymes. Oxidative stress induced by the assembly of reactive oxygen species was reduced after Rhododendron extract treatment under chromium toxicity as indicated by the enhanced contents of non-enzymatic antioxidants, namely ascorbic acid, tocopherol, and glutathione. Furthermore, Rhododendron leaf extract treatment under chromium metal stress also encouraged the biosynthesis of organic acids, polyphenols, as well as amino acids in Vigna radiata. Statistical analysis of the data with multiple linear regression also supported that Rhododendron leaf extract can effectively ease chromium metal-induced phytotoxicity in Vigna radiata.

“…. Salt stress in culture media can inhibit callus growth by ion imbalance, ion toxicity, water deficit, or a combination of any of these factors (Alhasnawi et al, 2015;Hosseini et al, 2012). In this context, Younis et al, (2010) reported that growth degradation caused by NaCl is because of the reduction of apical growth in cells, as well as the imbalance of endogenous hormonal growth.…”

Salinity stress causes a considerable reduction in callus growth. Mushroom polysaccharides (β-glucan) are the most promising groups of antioxidant compounds. An in vitro experiment was conducted to evaluate the potential function of exogenously applied β-glucan in alleviating the accumulation of antioxidants in rice callus. In this study, morphological, chemical, and biochemical parameters of an embryogenic callus of the rice variety, MR269, were investigated under 200mM NaCl stress conditions after pre-treatment with (0, 0.5, 1 and 1.5 mg/L) β-glucan in culture media. The present study sought to evaluate chemical, biochemical, and callus growth characterization. The results revealed that callus exposed to stressful media exhibited a significant decrease in callus growth and contents of K + and Ca +2. In addition, significant accumulation of Na + and Na + /K + was found, as well as an enhanced enzymatic antioxidant system and elevated proline activities under NaCl conditions. Furthermore, exogenous addition of β-glucan at 0.5-1.5mg/L under NaCl stress induced a pronounced, significant increase of callus growth, K + and Ca +2 contents, and enzymatic antioxidant and proline activities. In contrast, a significant decrease was found in the levels of Na + and Na + /K + , particularly in callus treated with NaCl. β-Glucan ameliorates the adverse effects of NaCl stress, and the extent of amelioration depends on the type of β-glucan agent as well as treatment duration (three months). The changes mentioned are important for determining the morphological, chemical, and biochemical parameters of salinity tolerance in callus. This study demonstrated that exogenous β-glucan exhibits alleviation of the harmful effects of salt stress and increases salinity resistance in callus rice.
