Alleviation of the effect of salinity on growth and yield of strawberry by foliar spray of selenium-nanoparticles

An Overview of Hazardous Impacts of Soil Salinity in Crops, Tolerance Mechanisms, and Amelioration through Selenium Supplementation

“…Rice (Oryza sativa L.) grown in salt-affected soil slightly impacted the K + ion contents; however, it enhanced the Na + contents in leaves and significantly lowered the K + /Na + ratio [56,57]. Furthermore, a significant reduction was reported in the growth of strawberry plants [58]. These growth retardations could partially be attributed to reduced photosynthetic activity due to decreased Chl a and Chl b under various salinity levels [59].…”

“…The findings to date have shown that Se is not ranked as an essential element for crop plants; however, a low Se concentration exerts beneficial effects on plant growth and development under biotic and abiotic stresses, especially soil salinization ( Figure 2). Many studies have reported the effects of the application of Se to evoke tolerance against salt stress depending on the application method, dose of Se, salinity levels, and plant species [58]. For example, a foliar application of selenate (20 mg·L −1 ) mitigated the adverse effects of salinity stress (12 dS m −1 ) on the growth and development parameters of maize (Zea mays L.) [122].…”

“…It is believed that enzymatic and non-enzymatic antioxidants, such as SOD, POD, APX, CAT, GSH-Px, and GR, are positively interconnected in response to Se supplementation to induce salinity tolerance in crop plants [22,131]. Researchers postulate that an elevation in the Se-mediated antioxidant defense is one of the vital mechanisms that can save plants from salt-stimulated oxidative stress [58,134]. Antioxidant enzyme activities (SOD, APX, and CAT) significantly improved with exogenous Se treatment in rapeseed (Brassica napus L.) and dill (Anethum graveolens) seedlings under salinity stress [24,147].…”

The use of nanotechnology to increase quality and yield of fruit crops

“…Nanofertilizers (NFs) are widely used in fruit crop nutrition as soil‐based and spray‐based applications that provide nutrients with high efficiency and low waste due to their faster and higher translocation to different parts of plants . After penetrating the leaf or root cuticle tissue, NFs move through different pathways (apoplastic, symplastic, lipophilic and hydrophilic), which influence their effectiveness, final fate and may also change their properties and therefore their reactivity, delivery and translocation inside plant tissues, which may result in various responses of different plant parts to the same NP …”

“…Fruits with nanopacking involve chitosan/nano‐silica and nano‐TiO 2 ‐LDPE (titanium dioxide–low‐density polyethylene), which have shown better physiochemical, physiological and preservation properties than those with normal packaging. Nanotechnology also plays important roles in increasing and improving plant growth by fertilization with essential nutrients, development, productivity, and quality of products derived from strawberry, mango, pomegranate and date palm and decreasing the harmful effects of stress caused by abiotic factors such as salinity in strawberry and alkalinity in grape . Moreover, fruit trees that received NFs were more vigorous and can overcome abiotic stress and maintain their fruit quality.…”
