“…The effect of salinity on water relationships, nutritional imbalance and ion toxicity is well documented (McKensie and Leshen 1994). Salinity causes a range of deleterious effects such as inhibition of photosynthesis, pigment synthesis, damage to plasma membrane permeability and other metabolic disturbances (Salisbury and Ross 1992, Ashraf and Parveen 2002, Karimi et al 2005. It is well known that Ca 2+ is involved in cell elongation, cell division, structural stability and permeability of cell membranes, regulation of cation-anion balance and activation of enzymes (Marschner 1995).…”

The apple (Malus domestica Borkh) rootstock M 4 shoots were grown in vitro for 4 weeks on Murashige and Skoog (MS) medium containing three NaCl concentrations (35, 100 and 200 mM) in combination with two CaCl 2 concentrations (5 and 10 mM). Inclusion of 10 mM CaCl 2 in the medium, in the presence of 35 mM NaCl, significantly increased the number of shoots and the fresh mass compared to 5 mM CaCl 2. The number of shoots, length of shoots, and the fresh mass of cultures were very low in the presence of 100 and 200 mM NaCl, independently of CaCl 2 concentration of the medium. By increasing NaCl and CaCl 2 concentrations in the culture medium, contents of N, Na, Cl, proline and soluble sugars in plantlets increased, whereas K, Mg, Β, Zn and chlorophyll content decreased in comparison to the control.

“…Salt stress limits plant growth by adversely affecting numerous physiological and biochemical processes, including photosynthesis, antioxidant capacity and ion homeostasis (Ashraf & Harris 2004). Relative water content (RWC), antioxidant enzymes activity, chlorophyll, proline content and stomata conductance have been used as indicators of plant stress (Ashraf & Parveen 2002;Maccaferri et al 2011). Rodriguez et al (2005) reported that chlorophyll content, leaf area and stomatal conductance declined under salinity stress.…”

In order to evaluate the effects of nano Zn-Fe oxide and bio fertilizer on physiological traits, antioxidant activity and yield of wheat under salinity stress, a factorial experiment was conducted based on RCBD with three replications.Treatments were included salinity in three levels (no-salt, salinity 25 and 50 mM NaCl), four bio fertilizers levels (no bio fertilizer, seed inoculation by Azotobacter, Azosperilium, Pseudomonas) and nano oxide (without nano, application of nano Zn oxide, nano Fe oxide and nano Fe-Zn oxide 1.5 g/lit). Salinty stress decreased the chlorophyll-a, chlorophyll-b, total chlorophyll, photochemical efficiency of PSII and yield of wheat, whearas electrical conductivity, soluble sugars, proline content, and the activities of Catalase (CAT), Peroxidase (POD) and Polyphenol Oxidase (PPO) enzymes increased. Similar results were observed in CAT, POD and PPO activities due to inoculation by bio fertilizers and nano oxide. Maximum of soluble sugars and proline content were observed in the highest salinity level and application of Pseudomonas. Application of nano Zn-Fe oxide increased about 17.40% from grain yield in comparision with no application of nano oxide in the highest salinity level. Generally, it was conducted that bio fertilizer and nano oxide can be used as a proper tool for increasing wheat yield under salinity condition.

“…Proline contents correlate indirectly with water content, stomatal conductivity, photosynthesis, and antioxidant enzyme activity. They have been used as indices of plant stress [ 56 , 57 ]. Proline lowers cytoplasmic pH, maintains the proper ratio of NADP + /NADPH in metabolism, increases various enzymes activities [ 58 ], and, importantly, acts as a source of energy, carbon, and nitrogen for tissue recovery under stress conditions [ 59 ].…”

The increasing use of nanofertilizers in modern agriculture and their impact on crop yield and pest management require further research. In this study, the effects of nano-Fe, -Zn, and -Cu (which are synthesized based on nanochelating technology), and urea (N) fertilizers on the antioxidant activities of wheat plants (cv. Chamran), and the wheat green aphid Schizaphis graminum (Rondani) are investigated. The authors observed the highest levels of phenolics in non-infested nano-Zn-treated plants (26% higher compared with control). The highest H2O2 levels are in the infested and non-infested nano-Zn-treated and infested nano-Fe-treated plants (in infested nano-Zn and nano-Fe treated plants, 18% and non-infested nano-Zn-treated plants, 28% higher compared with control). The highest peroxidase (POX) activity is observed in the infested and non-infested N-treated and non-infested water-treated plants (almost 14%, 37%, and 46% higher than control, respectively). The lowest activity is in the infested plants’ nano-Zn and -Fe treatments (almost 7 and 5 folds lower compared to the control, respectively). The highest and lowest catalase (CAT) activity are in the infested N-treated plants (almost 42% higher than control) and water-treated plants, respectively. The infested nano-Zn, -Fe, -Cu and Hoagland-treated plants showed the highest superoxide dismutase (SOD) activity. Regarding the antioxidant enzyme activities of S. graminum, the highest POX activity is in the nano-Cu treatment (more than two folds higher compared with control); the highest CAT and SOD activities are in the nano-Cu and -Zn treatments. It can be concluded that the application of nanofertilizers caused increasing effects on the wheat plant’s antioxidant system and its resistance to S. graminum.
