“…The increases were significant when compared with control treatment in both seasons. These results are consistent with the work of Hawrylak-Nowak (2008b), Abul-Soud and Abd-Elrahman (2016) and Castillo-Godina et al (2016). The effect of Se on plants depends mainly on its concentration.…”

he implementation of proper agricultural practices is important for reducing the effect of salt stress in plants. Therefore, this experiment was conducted in 2014/2015 and 2015/2016 seasons at Ras Sudr station of Desert Research Center, South Sinai Governorate, Egypt, to determine the most effective selenium (Se) dose and application method on lettuce plants Bruma cultivar under salt stress conditions. Six different Se treatments; Se0 (without application as a control), Se1 (seed soaking in 30 µmol l -1 for 12 h), Se2 (seed soaking in 50 µmol l -1 for 12 h), Se3 (foliar application of 10 µmol l -1 ), Se4 (foliar application of 20 µmol l -1 ) and Se5 (foliar application of 30 µmol l -1 ) were applied. The results showed that Se provision through both of the tested methods improved the plant leaf number, chlorophyll content, as well as N, P, K and Ca concentrations in the leaves, when compared with the control treatment. Moreover, Na content decreased in the leaves, which were treated than those of the control treatment. The plants grown under the Se treatments had larger heads and higher yields than the untreated plants. Foliar spraying was the most effective method of Se application of the lettuce plants, and the best results were obtained with the foliar spraying treatment at 20 µmol l -1 sodium selenate. These results suggest that applying the appropriate dose of Se via foliar spraying has the potential for use as an efficient and practical method of improving plant growth and enhancing salt-stress resistance in lettuce plants.

“…Generally, selenium nanoparticle application by foliar spraying resulted in higher contents of dry matter, N and K in the coriander plants under saline stress which has a positive impact on the permeability and activity the cellular membrane, redistribution of some essential elements and it regulated uptake. These results are consistent with the work of (Hawrylak-Nowak, 2008;Feng et al, 2013;Abul-Soud and Abd-Elrahman 2016;Castillo-Godina et al, 2016 andShalaby et al, 2017).…”

Nanotechnology is the field of science that opens a large scope of novel application in various fields, especially agricultural biotechnology. Selenium (Se) is an essential trace element for humans and animals and appears to be a beneficial element for many plants. There is increasing evidence showing that low selenium (Se) concentrations may build resistance of plants to environmental stresses. For this purpose, a pot experiment was carried out at The Experimental Farm of the Faculty of Agriculture, Mansoura University, Dakahlia Governorate, Egypt, during the spring season of 2016, to investigate the potential alleviation of salinity adverse effects by Se application as a foliar spray in the form of selenium nanoparticles (Se-NPs) in two concentrations (0 and 50 ppm) on coriander (Coriandrum sativum) grown on a sandy soil irrigated with different concentrations of saline water S1 (EC w =3.12 dS m-1), S2 (EC w =6.25 dS m-1) and tap water as a control S0 (EC w =0.45 dSm-1). These experimental treatments were arranged in a split plot design in three replications. Salinity showed adverse effects on different plant growth parameters as well as total chlorophyll content. Selenium nanoparticles (Se-NP1) at 50 ppm showed the best effects on vegetative growth and total chlorophyll content of coriander plants under different salinity levels of irrigation water. Increasing salinity resulted in decreasing N and K contents in the leaves of coriander plants, but Na increased as a result of some sort of antagonism with K; in spite of that, N and K contents in coriander leaves increased with foliar application of selenium nanoparticles (Se-NP1) at rate of 50 ppm to be higher concentrations compared to distilled water added to the spray as a control 0 ppm (Se-NP0). Values of Na/K ratio in coriander leaves increased as the salinity levels increased while, K/Na ratio was decreased. On the contrary, the values of Na/K ratio decreased with (Se-NP1) spraying at rate of 50 ppm, but K/Na ratio was increased at the same spraying rate under all salinity levels. It is concluded that application of selenium nanoparticles can mitigate salt stress damages on coriander plants; it also leads to increasing in K concentrations and decreasing in Na concentrations under salt stress.

“…Thus, selenium has positive effects on crops. Application of Na 2 SeO 3 (20 µM) increased yield of eggplants ( Solanum melongena ) under salt stress [ 52 ]. Moreover, NPs have useful effect on different physiological parameters, such as root and shoot growth in plant.…”

Salt stress severely reduces growth and yield of plants. Considering the positive effects of selenium (Se) and chitosan (Cs) separately against abiotic stress, in these experiments, we synthesized chitosan–selenium nanoparticles (Cs–Se NPs) and investigated their ability to reduce the negative effects of salt stress on growth and some biochemical parameters of bitter melon (Momordica charantia). Bitter melon plants were grown at three NaCl salinity levels (0, 50, and 100 mM) and a foliar spray of Cs–Se NPs (0, 10, and 20 mg L−1) was applied. Some key morphological, biochemical, and physiological parameters in leaf samples and essential oil from fruit were measured at harvest. Salinity decreased growth and yield while foliar application of Cs–Se NPs increased these critical parameters. Furthermore, Cs–Se NPs enhanced bitter melon tolerance to salinity by increasing antioxidant enzyme activity, proline concentration, relative water content, and K+, and decreasing MDA and H2O2 oxidants and Na aggregation in plant tissues. Yield was also improved, as the highest amount of essential oils was produced by plants treated with Cs–Se NPs. Generally, the greatest improvement in measured parameters under saline conditions was obtained by treating plants with 20 mg L−1 Cs–Se NPs, which significantly increased salinity tolerance in bitter melon plants.
