“…Higher plant exposure to salinity leads to higher accumulation of Na + concentration and restricts the flow of the K + ion, which is very important for the cellular, protein, and photosynthetic activity in plants. Our results are similar to those found by Siddiqui et al (2017).…”

Salinity is a serious problem that limits crop growth and yield. The present study used plotting to evaluate 25 tomato (Solanum lycopersicum L.) accessions for various morpho-physiological parameters at the seedling stage and identify significantly salt-tolerant tomato lines at three different salinity levels. The pot experiment had a completely randomized design with three replicates in a factorial arrangement under greenhouse conditions. Tomato plants were exposed to 0 (control), 8, and 12 dS m-1 as NaCl stress at the seedling stage. The morpho-physiological traits, such as root and shoot length, root/shoot ratio, number of leaves, fresh and dry shoot weight, fresh and dry root weight, leaf area, Na + and K + concentrations, K + /Na + ratio, and tolerance index, were recorded to examine salt tolerance. According to principal component analysis (PCA), there were six principal components (PCs) with Eigen values > 1 and 77.2% of total cumulative variability. The PC1 (24.3%) revealed the highest variability followed by PC2 (16.2%).

“…Furthermore, zinc usually maintained ATPase and Na + /H + antiport that facilitate Na + compartmentation under salinity (Shi et al 2016). The existing result supports the fact that maintenance of high K + / Na + is essential to sustain encouraging ion homeostasis that is generally recognized in salt tolerance criteria (Siddiqui et al 2017). The high K + /Na + , mainly in the shoots, might have a contribution to enhancing the growth performance of the zinctreated control plant under non-salinized or salinized condition.…”

Salinity is the principal natural obstacles for sustainable agriculture, adversely impacting 30% of the world's irrigated land, resulting in food insecurity, particularly in arid and semi-arid areas. Zinc has several functions in plants; nevertheless, the promising roles of nano-zinc oxide particle in plants under salinity stress are not clear. The current study aims to investigate the roles of zinc (water, 75 mg L −1 zinc sulfate (Zn), and 10 mg L −1 zinc oxide nanoparticle (ZNP)) on the mitigation of NaCl stress (6000 mg L −1) on morpho-physiological attributes and yield of canola plants. Salinity exhibited a substantial reduction in canola plant growth, enhanced photosynthetic pigment degradation, and decreased nutrient concentrations. A decrease in the overall yield and a decrease in various individual components were considerably stimulated by zinc application under nonsalinized and salinized conditions. Salinity caused a visible increase in membrane permeability (MP%), malondialdehyde (MDA), and hydrogen peroxide (H 2 O 2) concentrations. Interestingly, zinc application significantly decreased MP%, MDA, and H 2 O 2 concentrations by the upregulation of antioxidant enzymes (superoxide dismutase, catalase, peroxidase) and levels of non-enzymatic antioxidants (ascorbic, carotenoids, and total soluble phenolic compounds). Furthermore, zinc application also enhanced osmoregulation by increasing proline and total soluble carbohydrates accumulation, as well as increased nitrogen, potassium, and phosphorus in the plant tissues in correlation with a decline in sodium and chloride contents. Zinc's, especially ZNP, role in the mitigation the negative effects of salinity on canola growth and yield may be connected with the upregulating oxidative defense system and osmolyte synthesis as well as ionic regulation.

“…Siddiqui et al (2017) obtained similar results regarding Na + ions. In the wheat leaves of 10 cultivars, significant increases in Na + content, but decreases in K + content were found under salinity stress conditions [ 54 ]. The ratio of Na + /K + was significantly increased at all NaCl concentrations.…”

Anthocyanins of Coloured Wheat Genotypes in Specific Response to SalStress

The present study investigated the effect of salt stress on the development of adaptive responses and growth parameters of different coloured wheat genotypes. The different coloured wheat genotypes have revealed variation in the anthocyanin content, which may affect the development of adaptive responses under increasing salinity stress. In the early stage of treatment with salt at a lower NaCl concentration (100 mM), anthocyanins and proline accumulate, which shows rapid development of the stress reaction. A dose-dependent increase in flavonol content was observed for wheat genotypes with more intense purple-blue pigmentation after treatment with 150 mM and 200 mM NaCl. The content of Na+ and K+ obtained at different levels of salinity based on dry weight (DW) was more than 3 times greater than the control, with a significant increase of both ions under salt stress. Overall, our results demonstrated that coloured wheat genotypes with high anthocyanin content are able to maintain significantly higher dry matter production after salt stress treatment.
