“…In comparison to the control group, this led to an increase in the levels of total chlorophyll (13.3 mg/g), carotenoids (1.2 mg/g), and the chlorophyll a/b ratio (7.4 mg/g). Our results are consistent with those of Khan et al, who found that using the phenolic component salicylic acid increased chlorophyll and carotenoid levels by 52.6 and 62.8%, respectively . Elblasy et al and Munsif et al discovered similar patterns in chlorophyll content augmentation in soybean and wheat plants, respectively. , The chlorophyll contents steadily reduced as the resorcinol concentration increased.…”

“…Topal describes resorcinol as an aromatic hydrocarbon group with a benzene ring structure and a two-hydroxyl functional group (−OH) in the ortho position .

Climate variability has been a catalytic factor in inducing both biotic and abiotic stresses, exerting detrimental impacts on crop yields. This, in turn, leads to the manifestation of biochemical and physiological impairments within plant systems. This study aimed to evaluate the effects of different concentrations of resorcinol and biochar on tomato (Lycopersicon esculentum Mill.) growth, primary and secondary metabolites, and antioxidant enzyme content levels. Biochar was synthesized from Cedrus deodara (Roxb. ex D. Don) G. Don, sawmill shavings using pyrolysis and subjected to comprehensive characterization employing contemporary techniques including scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD) analysis, Fourier transform infrared (FTIR) spectroscopy, and UV−vis spectroscopy (UV). Both resorcinol at 0.1 μM/L and biochar at 30 mg/L significantly enhanced tomato seed germination and plant growth, promoting increased shoot/root length and fresh/dry weights in tomato plants compared to controls. This supplementation also amplifies tomato chlorophyll contents, growth metabolites, and antioxidant enzyme activities, contributing to robust plant development. Resorcinol at 0.1 μM/L concentration significantly enhanced total protein (79.9 μg/g), total phenol (58.8 μg/g), total proline (0.03 μg/g), total lipid (3.8 μg/g), total soluble sugar (42.5 μg/g), and flavonoid (0.09 μg/g) as compared to control. Biochar at 30 mg/L concentration showed maximum values of total protein (92.1 μg/g), total phenol (61.3 μg/g), total proline (0.03 μg/g), total lipid (5.5 μg/g), total soluble sugar (48.9 μg/g), and flavonoid (0.08 μg/g). This research indicated that foliar application of these specific concentrations of resorcinol and biochar has the ability to improve tomato plant growth, osmolytes, and antioxidant activity. ■ RESEARCH HIGHLIGHTS(1) Resorcinol (0.1 μM/L) and biochar (30 mg/L) significantly enhance tomato germination and growth, leading to higher shoot/root length and fresh/dry weights than controls (2) Resorcinol (0.1 μM/L) and biochar (30 mg/L) significantly enhance phytohormone levels, primary and secondary metabolite concentrations, and antioxidant enzyme activities in tomato plants.

Soybean is a very important food legume because of its high protein and oil concentrations. However, soybean is vulnerable to drought stress, which has become more severe and occasional in many regions worldwide. To alleviate drought’s influence, the application of certain agents is increasingly gaining attention as it is economically affordable and practically applicable. Acetic acid (AA) is, by far, one of the cheapest agents that are reported to have potential benefits against drought; however, no accurate data on its influence on soybean genotypes differing in their drought tolerance are published. An experiment was conducted in a controlled environment to evaluate the effects of AA on the morpho-physiology of two soybean (Glycine max (L.) Merr.) genotypes: drought-tolerant ‘Speeda’ and drought-susceptible ‘Coraline.’ Chlorophyll-a and total carotenoids, stomatal conductance, and specific leaf area of both soybean genotypes decreased under water deprivation conditions. However, AA application enhanced these traits significantly. Drought reduced the optimal and the actual photochemical efficiency of PSII of ‘Coraline,’ but not ‘Speeda.’ The application of AA could not enhance the relative water content of both genotypes. Root and shoot morphology were negatively influenced by drought in both genotypes; however, AA helped in restoring these traits in ‘Coraline,’ but not ‘Speeda,’ indicating that AA application might be more beneficial in the case of drought-susceptible soybean genotypes.
