“…In this study, 250 mg/L SA increased the POD activity of N. officinale under Cd-contaminated condition, and 150, 200, and 250 mg/L SA increased the CAT activity. These results are not completely consistent with the previous report on Cyphomandra betacea (Liu et al, 2022) but consistent with the observations in pea (Popova et al, 2009;Khan et al, 2021), indicating that SA has different impacts on the various plants' antioxidant system. On the other hand, SA inhibits the activity of key enzymes, including POD, polyphenol oxidase, and phenylalanine ammonia lyase, to slow down lignin synthesis, delaying senescence (Wu et al, 2006).…”

“…For rice, SA treatment increased its antioxidant enzyme activity and decreased the H 2 O 2 content to enhance the resistance to Cd stress (Guo et al, 2007); this also decreases the rice Cd content (Majumdar et al, 2020;Pan et al, 2021). Various other studies have shown similar effects of SA on mung beans, kidney beans and tomatoes under Cd stress (Tissa et al, 2000;Khan et al, 2021). In addition, SA also has demonstrated the effects on hyperaccumulators.…”

IntroductionCadmium (Cd) contamination is a severe problem in paddy soils that has affected crops’ safety. The present study aimed at remediating Cd-contaminated paddy soil by improving the phytoremediation capability of aquatic accumulator plants.MethodsWe conducted an experiment to investigate the effects of salicylic acid (SA) on the growth and Cd phytoremediation capability of the aquatic accumulator plant Nasturtium officinale.ResultsSA with the concentrations of 100, 150, and 200 mg/L increased the root and shoot biomass of N. officinale, while only 150 mg/L increased the chlorophyll a and b contents. SA increased the activities of peroxidase and catalase of N. officinale to a great extent, but decreased the superoxide dismutase activity and soluble protein content. SA also increased the root Cd content, shoot Cd content, root Cd extraction, and shoot Cd extraction to a large extent. At concentrations of 100, 150, and 200 mg/L, SA increased the shoot Cd extraction by 17.59%, 47.16%, and 43.27%, respectively, compared with the control. Moreover, SA concentration had a quadratic polynomial regression relationship with the root Cd extraction and shoot Cd extraction. The correlation and grey relational analyses revealed that root Cd extraction, shoot biomass, and root biomass were closely associated with shoot Cd extraction of N. officinale.ConclusionThus, our results suggest that SA promoted the growth and improved the phytoremediation (extraction) capability of N. officinale, and 150 mg/L SA was the most suitable concentration.

“…Our results demonstrated that the application of N-P fertilizers under a low-W regime considerably reduced the ROS. This may be related to the enhancement of antioxidant enzyme activities (SOD, CAT, and POD) under N-P supply (Figures 2G-I), since N-P nutrition could improve the synthesis and physiological activities of antioxidant enzymes (Khan et al, 2021;Roy et al, 2021a,c). Therefore, the addition of N-P fertilizers under waterlimited environments can improve the plant water status, the osmolytes content, and the activity of antioxidant enzymes, favoring the ROS homeostasis (low production of H 2 O 2 and O •−…”

Surface mining is a critical anthropogenic activity that significantly alters the ecosystem. Revegetation practices are largely utilized to compensate for these detrimental impacts of surface mining. In this study, we investigated the effects of five water (W) regimes [W40: 40%, W48: 48%, W60: 60%, W72: 72%, and W80: 80% of field capacity (FC)], five nitrogen (N) (N0: 0, N24: 24, N60: 60, N96: 96, and N120: 120 mg kg−1 soil), and five phosphorus (P) fertilizer doses (P0: 0, P36: 36, P90: 90, P144: 144, and P180: 180 mg kg−1 soil) on morpho-physiological and biochemical parameters of Ammopiptanthus mongolicus plants to assess the capability of this species to be used for restoration purposes. The results showed that under low W-N resources, A. mongolicus exhibited poor growth performance (i.e., reduced plant height, stem diameter, and dry biomass) in coal-degraded spoils, indicating that A. mongolicus exhibited successful adaptive mechanisms by reducing its biomass production to survive long in environmental stress conditions. Compared with control, moderate to high W and N-P application rates greatly enhanced the net photosynthesis rates, transpiration rates, water-use efficiency, chlorophyll (Chl) a, Chl b, total Chl, and carotenoid contents. Under low-W content, the N-P fertilization enhanced the contents of proline and soluble sugar, as well as the activities of superoxide dismutase, catalase, and peroxidase in leaf tissues, reducing the oxidative stress. Changes in plant growth and metabolism in W-shortage conditions supplied with N-P fertilization may be an adaptive strategy that is essential for its conservation and restoration in the desert ecosystem. The best growth performance was observed in plants under W supplements corresponding to 70% of FC and N and P doses of 33 and 36 mg kg−1 soil, respectively. Our results provide useful information for revegetation and ecological restoration in coal-degraded and arid-degraded lands in the world using endangered species A. mongolicus.

“…Drought can also induce the excessive generation of reactive oxygen species (ROS) in plants; and thereby results in oxidative stress ( Cruz de Carvalho, 2008 ). In addition, salinity and HMs stress are also considered among the environmental factors that limit crop yield in many countries ( Abd El-Mageed et al, 2018 ; Ye et al, 2019 ; Sofy et al, 2020 ; Taha et al, 2020 ; Dustgeer et al, 2021 ; Khan et al, 2021 ; Seleiman et al, 2022 ).…”

Plants are subjected to a wide range of abiotic stresses, such as heat, cold, drought, salinity, flooding, and heavy metals. Generally, abiotic stresses have adverse impacts on plant growth and development which affects agricultural productivity, causing food security problems, and resulting in economic losses. To reduce the negative effects of environmental stress on crop plants, novel technologies, such as nanotechnology, have emerged. Implementing nanotechnology in modern agriculture can also help improve the efficiency of water usage, prevent plant diseases, ensure food security, reduce environmental pollution, and enhance sustainability. In this regard, nanoparticles (NPs) can help combat nutrient deficiencies, promote stress tolerance, and improve the yield and quality of crops. This can be achieved by stimulating the activity of certain enzymes, increasing the contents (e.g., chlorophyll) and efficiency of photosynthesis, and controlling plant pathogens. The use of nanoscale agrochemicals, including nanopesticides, nanoherbicides, and nanofertilizers, has recently acquired increasing interest as potential plant-enhancing technologies. This review acknowledges the positive impacts of NPs in sustainable agriculture, and highlights their adverse effects on the environment, health, and food chain. Here, the role and scope of NPs as a practical tool to enhance yield and mitigate the detrimental effects of abiotic stresses in crops are described. The future perspective of nanoparticles in agriculture has also been discussed.
