“…These reports suggest that most of the agronomically important crop species are not compatible with high salt levels, as uttered in a review by Parihar et al [ 4 ]. Furthermore, the Food and Agriculture Organization (FAO) reports stated that salinity is a serious threat to over 6% of the world’s land [ 4 ] and the relevant reports anticipate that salinity will severely affect more than 50% of arable land by 2050 [ 9 ]. For this reason, the use of new methods and strategies to decrease the negative effects of salinity has gained great importance.…”

High salt levels are one of the significant and major limiting factors on crop yield and productivity. Out of the available attempts made against high salt levels, engineered nanoparticles (NPs) have been widely employed and considered as effective strategies in this regard. Of these NPs, titanium dioxide nanoparticles (TiO2 NPs) and selenium functionalized using chitosan nanoparticles (Cs–Se NPs) were applied for a quite number of plants, but their potential roles for alleviating the adverse effects of salinity on stevia remains unclear. Stevia (Stevia rebaudiana Bertoni) is one of the reputed medicinal plants due to their diterpenoid steviol glycosides (stevioside and rebaudioside A). For this reason, the current study was designed to investigate the potential of TiO2 NPs (0, 100 and 200 mg L−1) and Cs–Se NPs (0, 10 and 20 mg L−1) to alleviate salt stress (0, 50 and 100 mM NaCl) in stevia. The findings of the study revealed that salinity decreased the growth and photosynthetic traits but resulted in substantial cell damage through increasing H2O2 and MDA content, as well as electrolyte leakage (EL). However, the application of TiO2 NPs (100 mg L−1) and Cs–Se NPs (20 mg L−1) increased the growth, photosynthetic performance and activity of antioxidant enzymes, and decreased the contents of H2O2, MDA and EL under the saline conditions. In addition to the enhanced growth and physiological performance of the plant, the essential oil content was also increased with the treatments of TiO2 (100 mg L−1) and Cs–Se NPs (20 mg L−1). In addition, the tested NPs treatments increased the concentration of stevioside (in the non-saline condition and under salinity stress) and rebaudioside A (under the salinity conditions) in stevia plants. Overall, the current findings suggest that especially 100 mg L−1 TiO2 NPs and 20 mg L−1 Cs–Se could be considered as promising agents in combating high levels of salinity in the case of stevia.

“…Under salt stress conditions, plants are increase the uptake of Na + ions that affected uptake of other ions like K + that leads to cause the K + deficiency resulting the lowering of K + /Na + ratio (Kibria et al, 2017). Salt stress induced the significant changes in physiological and biochemical conditions in plant, for example.…”

“…Under salt stress, salt-sensitive and salt-tolerant plants show differential responses towards K + /Na + ions ratio in both root and shoot tissues (Zheng et al, 2012). Some crops like potato showed a decrease in K + /Na + ratio under salt stress that causes Na + toxicity leads to cellular damage whereas deficiency of K result decreases crop growth and productivity of plants (Daneshmand et al, 2009;Kibria, Hoque, 2019).…”

Salt stress is the most prominent factor that has affected agriculture production, induced various problems, and a serious challenge to food security. Numerous adverse effect can be noticed during salt stress that is pretentious to their physiological, biochemical, molecular, and morphological functions. Plants develop a mechanism to subdue the problem that arises through salt stress via adoption or tolerance process but these mechanisms are not sustainable. It leads to a decline in the biomass of plants and overall crop productivity. For sustainable development of food security and overcome the looming endanger of salt stress in the reduction of food production and exponential population growth, novel and advanced technologies like plant breeding, biotechnology, nanotechnology can be explored and made to work for the development of salt tolerance of crop varieties.

“…Salt stress hampers plant progress and limits yield by interfering photosynthetic rate (7) and accumulation of toxic such as Na + and Clions (8). Several studies reported soil salinity decreased chlorophyll content (9), increased ROS (10), nutritional disorder (11) and ionic imbalance in plants (12), which finally contributed to significant yield loss (13).…”

Crop production is unexpectedly hampered by different abiotic stresses. Salinity is one of the leading stresses, which snappishly hampers plant developmental progression. Local rice landraces exhibit noticeable salt tolerance as well as high yield. However, research is scarce about the physio-biochemical responses of local landraces and modern cultivar under saline conditions. Therefore, the present experiment was designed to reveal the physio-biochemical responses of local landraces and modern cultivar under salinity stress. Five landraces (Jotai, Icheburogolghor, Morishal, Chapail, Kumro buro) and two modern cultivars (BR23 and BRRI dhan41) were subjected to 0, 20, 40, 60 and 80 mM NaCl treatment. The effects of salt stress on morphological parameters, proline contents, and activities of antioxidant enzymes were assessed. Salt stress reduces the morphological parameters of all tested cultivars. The Morishal and BRRI dhan41 exhibited higher growth of plant and physiological parameters than other cultivars under the highest salinity. The catalase (CAT) and ascorbate peroxidase (APX), exhibited a significant increase whereas peroxidase (POX) activity significantly declined in all the cultivars under salinity stress. Morishal and BRRI dhan41 showed the highest proline content under the maximum saline condition. These results suggest that the high tolerant landrace and modern cultivars were Morishal and BRRI dhan41 respectively. These results also suggest that Morishal and BRRI dhan41 exhibited high tolerance to salinity by enhancing proline content and antioxidant enzyme activities.
