“…The increases reached in yield can be derived from many processes in which SA is involved, including an increase in root growth [38]. Also, a greater absorption of nutrients, protein synthesis, division, and cell differentiation, associated to an increase in yield, have been observed [39].…”

The use of elicitors or biostimulants such as salicylic acid (SA) is an emerging novel practice to improve the yield and quality of crops since it plays an important role in the regulation of various physiological and metabolic processes. The objective of this research was to study the effect of the foliar application of SA on the nutraceutical quality and yield of tomato fruits. A completely randomized experimental design with 10 repetitions was used. SA was applied at five doses (0.025 mM, 0.05 mM, 0.075 mM, 0.1 mM, and 0.125 mM) every 15 days through foliar sprays after transplantation, accumulating seven applications through the cycle. The response variables were yield (total fruit weight per plant), fruit parameters (weight, diameter, firmness, and total soluble solids), percentage of weight loss, and nutraceutical quality. The obtained results suggest that the foliar spraying of SA improves the yield and biosynthesis of phytochemical compounds in tomato fruits, compared to control plants. According to the results, it is advisable to use the dose of 0.125 mM of SA since it has a higher content of bioactive compounds without compromising yield.

“…RL and root to shoot ratio were regarded as reliable criteria for selecting drought stress‐tolerant and persistent genotypes of turfgrass in semi‐arid and arid regions (Karcher et al., 2008). Some studies indicated that the application of growth regulators such as salicylic acid (SA) could improve root systems and increase drought tolerance in plants (Askari & Ehsanzadeh, 2015; Hunter et al., 2013; Ullah et al., 2018).…”

Variation in persistency, postdrought recovery and root characteristics in a tall fescue germplasm under interactive effects of exogenously applied salicylic acid and water stress

This study was performed for a better understanding of genotypic responses of a germplasm of tall fescue to different prolonged drought stresses and exogenously applied salicylic acid (SA) in terms of drought tolerance, postdrought recovery, persistence and root‐related traits. Twenty‐one diverse tall fescue genotypes were evaluated under three irrigation treatments (IT) (normal, mild and intense drought stress) and the presence of two SA concentrations (0 and 1 mM) during 2015–2017. In the fourth year (2018), irrigation was withheld in all treatments for two months in summer (severe drought) and then plants were rewatered to investigate the effect of previous treatments on the mentioned traits. Results indicated that recovery after severe drought and persistence in tall fescue depends on previous environmental conditions with clear differences in genotypic responses. Foliar application of SA improved forage production, drought tolerance, postdrought recovery and most of the root traits, while it had a negative effect on persistence and root length. Associations amongst traits under different treatments and selection of superior genotypes will be discussed.

Insufficient attention has been paid to the physiological responses of sesame to drought and it is unclear if exogenous plant growth regulators are beneficial to drought-stressed sesame. Thus, a field study was conducted on seven Sesamum indicum genotypes affected by two levels of irrigation (60 and 80% depletions in available soil water) and by foliar-applied salicylic acid (SA; 0 and 0.6 mM). Water deficit led to depressions in net photosynthetic rate, stomatal conductance, leaf area index, chlorophyll a, b, and total chlorophyll contents, maximum quantum efficiency of PSII, and plant dry matter and seed yield, despite increases in carotenoid concentration, superoxide dismutase, catalase, peroxidase, and ascorbate peroxidase activities. SA was found beneficial in ameliorating the depressions in all of the above characteristics, indicating that it could be applied for lessening the harmful effects of the drought stress.
