“…Exogenous application of salicylic acid has been shown to accelerate plant growth and development, as well as to initiate or boost secondary metabolite production in various plant species, such as Mentha piperita L., Achillea millefolium L., Ocimum basillicum L., Thymus vulgaris L., and others [13][14][15][16][17]. The Food and Drug Administration recognizes salicylic acid as a "Generally Regarded As Safe" compound to apply to medicinal species cultivated for the phytomedicine industry [18].…”

“…The Food and Drug Administration recognizes salicylic acid as a "Generally Regarded As Safe" compound to apply to medicinal species cultivated for the phytomedicine industry [18]. The effect of exogenously applied salicylic acid on plant development varies depending on the plant species and its developmental stage, as well as the salicylic acid concentration [16].…”

Silymarin, a secondary metabolite found mainly in the Silybum marianum L. fruits, has been associated with the hepatoprotective activity of the plant. Among various elicitors, salicylic acid, a “Generally Regarded As Safe” compound recognized by the Food and Drug Administration, is one of those being used in the induction and enhancement of valuable plant secondary metabolite production in various plant species. In this study, two concentrations (10−4 and 10−3 molar) of salicylic acid have been applied to the S. marianum plants as foliar spray to investigate their effects on plant growth and yield, as well as the production of its bioactive compound, silymarin. Our results indicated that both concentrations of salicylic acid increased the plant height, the number of branches, leaves, and capitula, as well as the dried weight of roots, aerial parts, and fruits. The enhancement effects in plant growth and yield were accompanied by an increase in photosynthetic pigments such as chlorophyll-a, b, and carotenoids as well as element contents such as nitrogen, phosphorus, and potassium. The potential of salicylic acid as an elicitor for the enhancement of secondary metabolites in S. marianum was supported by the increase in silymarin’s major components, silybin (A + B), in the salicylic acid-treated plants. Concomitant expressions of CHS1, 2, and 3 genes that have been associated with the production of silymarin in S. marianum were also observed in the salicylic acid-treated plants. A lower concentration (10−4 M) of salicylic acid was found to be a better elicitor as compared with the 10−3 M salicylic acid. An increase of 3.4 times in capitula number and fruit dried weight as well as 2.6 times in silybin (A + B) contents were observed in plants sprayed with 10−4 M of salicylic acid as compared with the control.

“…Moreover, foliar-applied SA resulted in significant increments in Ca + and K + content within plants, which improved cell walls permeability for nutrients present in the cell sap [29][30][31][32]. Furthermore, it boosted plant growth and development by reducing the biosynthesis of ethylene and preventing micronutrient toxicity, and through lipid peroxidation, which protected the crop plants from membrane damage [33][34][35][36]. SA's roles in regulating the physiological and biochemical activities of plants, such as the germination of seeds, nodulation in legumes, the regulation of stomatal conductance, respiration, delaying fruit ripening, preventing leaf senescence and enhancing fruit yield, have been previously reported [16,23,36].…”

Globally, optimized doses of exogenously applied growth regulators hold the potential to sustainably boost the growth and productivity of leguminous crops, including green gram. A field investigation was undertaken at the Agronomy Farm of the University of Agriculture Faisalabad, Pakistan in 2021–2022 to determine the highest-performing doses of foliar-applied salicylic acid (S1 = 0 and S2 = 75 ppm) and gibberellic acid (G1 = 0, G2 = 30, G3 = 60, G4 = 90 and G5 = 120 ppm) for green gram (cv. NIAB-MUNG 2011) sown under irrigated conditions in a semiarid climate. The response variables included physiological growth traits (CGR and net assimilation rate (NAR)), yield attributes (plant height (PH), PBs and the number of pods per plant−1 (NP), pod length (PL) and SW, grain (GY) and biological yields (BY), the biosynthesis of pigments (chlorophyll a, chlorophyll b and total chlorophyll along with carotenoids) and protein (P) contents. The results revealed that S2G5 remained unmatched in that it exhibited the highest crop growth rate, while it remained on par with S2G4 and S2G3 in terms of its net assimilation rate. Additionally, S2G5 maximized plant height, the number of pod-bearing branches and pods per plant, pod length, seed number per pod−1 and 1000-seed weight, which led to the highest grain yield and biological yield (104% and 69% greater than those of the control, respectively). Moreover, the same treatment combination also surpassed the rest of the treatments because it recorded the largest amounts of chlorophyll and carotenoid contents, and the P content was increased to 24% greater than that observed for the control treatment. Thus, the exogenous application of salicylic acid (75 ppm) and gibberellic acid (120 ppm) might be recommended to green gram growers to sustainably increase the plant’s yield and nutritional value, and these findings may serve as a baseline for conducting more studies to test higher doses of these growth regulators.
