“…Existing studies reported that chemical pesticides induced over-accumulation of ROS in plant cells which eventually caused severe damage in growth, nutrient assimilation, photosynthesis, etc. 45 – 47 . However, the data of this study showed that physcion has no significant effect on the level of ROS in the root and leaf cells of maize seedlings (Fig.…”

The use of biopesticides has gradually become essential to ensure food security and sustainable agricultural production. Nevertheless, the use of single biopesticides is frequently suboptimal in agricultural production given the diversity of biotic and abiotic stresses. The present study investigated the effects of two biopesticides, physcion and chitosan-oligosaccharide (COS), alone and in combination, on growth regulation and antioxidant potential of maize seedlings by seed coating. As suggested from the results, physcion significantly inhibited the growth of the shoots of maize seedlings due to the elevated respiration rate. However, COS significantly reduced the growth inhibition induced by physcion in maize seedlings by lowering the respiration rate and increasing the content of photosynthetic pigments and root vigor, which accounted for lower consumption of photosynthesis products, a higher photosynthetic rate and a greater nutrient absorption rate. Thus, an improved growth was identified. As indicated from the in-depth research, the application of physcion and COS combination is more effective in down-regulated the malondialdehyde (MDA) content by facilitating the activities of the antioxidative enzymes (i.e., superoxide dismutase (SOD), catalase (CAT) and guaiacol peroxidase (G-POD)). Such results indicated that the combined use of physcion and COS neither affected the normal growth of maize seedlings, but also synergistically improved the antioxidant potential of the maize plants, resulting in plants with high stress resistance. Thus, the combined use of physcion and COS by seed coating in maize production has great potential to ensure yield and sustainable production of maize.

“…Pre-treatment of SA might induce a pre-adaptive response through a transient increase in H 2 O 2 level, which may act as a second messenger to “set up” the plant to defend the following salt stress that may occur. Pre-treatment with SA enhances the activities of antioxidant enzymes in plants, which in turn decreases stress-induced oxidative stress, as has been noted in Leymus chinensis [ 83 ] and Iris pseudacorus [ 87 ]. The signalling role of SA is also cross-linked with ABA, glycinebetaine, and ethylene (ET), as they are closely correlated with the synthesis of stress proteins and maintenance of leaf water potential [ 88 , 89 ].…”

In recent decades, many new and exciting findings have paved the way to the better understanding of plant responses in various environmental changes. Some major areas are focused on role of phytohormone during abiotic stresses. Salicylic acid (SA) is one such plant hormone that has been implicated in processes not limited to plant growth, development, and responses to environmental stress. This review summarizes the various roles and functions of SA in mitigating abiotic stresses to plants, including heating, chilling, salinity, metal toxicity, drought, ultraviolet radiation, etc. Consistent with its critical roles in plant abiotic tolerance, this review identifies the gaps in the literature with regard to the complex signalling network between SA and reactive oxygen species, ABA, Ca2+, and nitric oxide. Furthermore, the molecular mechanisms underlying signalling networks that control development and stress responses in plants and underscore prospects for future research on SA concerning abiotic-stressed plants are also discussed.

“…This is because they are cost-effective and easy to use in locally grown varieties. The foliar application of SA has also been shown to be an adequate strategy to mitigate abiotic stresses (El Dakak and Hassan 2020;Liu et al 2021). However, the comparative efficiency of methods SA application has not been well tested yet, even there are contradictory reports on seed priming, root or foliar efficiency of SA application (Souri and Tohidloo 2019).…”

This study aimed to assess the capacity of two methods of application of salicylic acid (SA) to mitigate the effects of water deficit during the vegetative growth of tomato (Solanum lycopersicum L.) plants comparatively evaluated by growth, physiological and biochemical responses. Under greenhouse conditions, a combination of two factors was tested. The first was SA application: without SA, seed priming with SA, and soil drench with SA solution at 19 days after seedling emergence. The second factor, water limitation (20, 30, 40, and 100% of water holding capacity of the substrate) was applied 28 days after seedling emergence for 5 days. Results showed that plant growth and photosynthetic activity were significantly inhibited by the water deficit. On the other hand, water use efficiency, activities of superoxide dismutase, ascorbate peroxidase, catalase and contents of malondialdehyde, hydrogen peroxide and osmoprotectants were significantly increased by water deficit. Seed priming with SA induced increases in leaf area, root dry weight and root/shoot ratio under drought conditions. Soil drench with SA induced improvements in CO 2 assimilation rate and stomatal conductance in well-irrigated plants. Even when, in general, the activity of antioxidant enzymes was not increased by the application of SA, the cellular redox homeostasis was maintained through increases in the contents of proline and total soluble sugars from the degradation of starch. Seed priming with SA is a suitable technique to mitigate the damaging effects of severe water deficit while maintaining plant growth.
