“…However, the high concentration of stresses may result in destruction with respect to pigment synthesis, which was indicated by the decrease in absorbance of stressed samples at a higher concentration. These findings were consistent with previous results for maize, wheat, 25,26 and peanut 27 plants, where the optimum concentration of NaCl (50–100 m m ) and tyrosine (100 mg L −1 ) exhibited an increase in photosynthetic pigments. Likewise, these observations accordingly suggested that the optimized concentrations of H 2 O 2 (97 m m ), catechin (0.50 m m ), gallic acid (0.30 m m ), tyrosine (0.28 m m ), and NaCl (85.50 m m ) may play a significant role in increasing the betacyanin content in djulis sprouts during germination.…”

BACKGROUND: Germination is regarded as a natural method for improving the bioavailability of seed nutrients against stress, which enhances the accumulation of bioactive compounds. The present study aimed to determine the effect of stress (H 2 O 2 , catechin, gallic acid, tyrosine, and NaCl) during germination of djulis (Chenopodium formosanum Koidz.) sprouts on betacyanin, phytochemicals, and antioxidant capacities.RESULTS: The betacyanin and antioxidant activities of the djulis sprouts increased significantly compared to seeds. The lowest betacyanin was found in NaCl-stressed sprouts. The djulis sprouts reported the presence of celosianins I and II (50.72%), which was absent in seeds. Hydroxycinnamic acids accounted for > 60% of the total phenolic compounds in sprouts, whereas rutin predominated in the seeds.CONCLUSION: Germination under stress may represent an effective natural method for improving the bioactive potential of sprouts, an alternative to use seeds, in the development of bioactive compounds-enriched healthy foods that are good for public health.

“…The positive effect of using amino acids on fatty acid constituents of peanut oil yield (Table 5) is consistent with Ramadan et al (2019) findings by using L-arginine on sunflower plant and Bakry et al (2020) by using tyrosine on peanut plants. These reductions in saturated fatty acids concomitant with the increases in unsaturated fatty acids.…”

“…In addition, it is an amazing plant-based source of oil, protein, vitamins, minerals, and plant components. The nutritive value of peanut seeds is very high as it contains 40-50 percent of oil, 25-30 percent protein, 20 percent carbohydrates and 5 percent ash, some minerals as magnesium and calcium depending on the variety and agricultural treatments (Li et al, 2014;Jani and Devani, 2020;Bakry et al, 2020). Moreover, peanut leaves were used as animal feed (Atasie et al, 2009;Suchoszek-Lukaniuk et al, 2011).…”

Two field experiments were conducted during 2019 and 2020 summer seasons at the experimental station of national research center, Al-Nubaryia district, El-Behaira Governorate, Egypt, to study the effect of Phenyl alanine and Aspartic acid foliar fertilizers at rates of (0.0, 50, 75 and 100 ppm) on morphological characters, photosynthetic pigments, seed yield and its components as well as seed quality of groundnut grown under sandy soil. Results indicated superiority of aspartic acid over phenyl alanine on increasing different growth parameters, chlorophyll b, biological and seed yields/plant, biological, seed and oil yields (kg/fed.), % of carbohydrate in peanut seeds. Meanwhile, phenyl alanine was superior on increasing carotenoids, indole acetic acid, phenolics, free amino acids, flavonoids, Lycopene, β-Carotene contents, antioxidant activity expressed as (1,1-diphenyl-2-picrylhydrazyl DPPH %) and shilling percentage. In addition, aspartic acid and phenyl alanine with various levels caused significant increases in growth and seed yield quantity and quality of peanut plants through increases in photosynthetic pigments, indole acetic acid, phenolics and free amino acids contents. Aspartic acid was more effective than phenyl alanine, Foliar treatment with 100 mg/L aspartic acid increased oil yield (700.36 over 568.05 ton/fed.) and seed yield (1531.98 over 1253.49 kg/fed.). Finally, it can conclude that using aspartic acid and phenyl alanine as foliar treatment improved growth and yield of ground nut plants under sandy soil.

“…Some evidence of A CO2 and g s regulation has already been published by Kong et al [36], but the possible mechanisms involved in these effects are still unknown. Bakry et al [37] observed that exogenous application of Tyr in concentrations of 0.27, 0.55, and 0.83 mM improved growth by increasing the photosynthetic pigments of the plants. Likewise, in an assay with lettuce plants to which Met was applied through the roots in a hydroponic system, better results were obtained with the lowest doses (0.0013 and 1.3•10 −7 mM), highlighting that these doses improved the photosynthetic activity and also showed an increase in performance.…”

Application of Biostimulants Containing Amino Acids to Tomatoes Could Favor Sustainable Cultivation: Implications for Tyrosine, Lysine, and Methionine

et al. 2020

Tomato (Solanum lycopersicum L.) is one of the most important crops worldwide as per its production and the surface cultivated. The use of biostimulant products plays a fundamental role in mitigating the negative effects of climate change and reducing the use of conventional fertilizers. Many of these products are formulated with amino acids (AAs). This study was conducted to elucidate the effects of the foliar application of tyrosine (Tyr) (15 mM), lysine (Lys) (15 mM), methionine (Met) (15 mM), and a Tyr + Lys + Met (15 mM + 15 mM + 15 mM) mixture on the physiological and metabolic processes, vegetative growth, and nutritional state of Optima variety tomato plants. The results showed that application of the AAs, individually and combined, was beneficial for the growth of the aerial part, net assimilation of CO2, and water use efficiency (WUE). Application of Tyr resulted in the best WUE. The metabolomics study revealed that AA treatments increased the concentration of proline, fructose, and glucose, whose role was to stimulate glycolysis and the Krebs cycle. Thus, the plants could have greater reduction power and energy, as well as more carbon molecules for their growth processes.
