“…The addition of amino acids (polyamine precursors) has, on the other hand, resulted in an increase in chl b in both cultivars (Tyagi et al, 2023). Similar results have been reached with garlic plants (El-Shabasi et al, 2005), and sweet pepper (Tyagi et al, 2023) Al-Said & Kamal, 2008. This increase may be due to the role of amino acid mixture in detoxification of harmful accumulated of ROS in the thylakoid membrane during photosynthesis.…”

Background Salt stress, a significant environmental problem was studied in barley cultivars Giza 124 and Giza 119 at various stages (seedling, pre-flowering, and yield). This study aimed to investigate the impact of salt stress on these cultivars, examine the effects of polyamine precursors (arginine, methionine, and ornithine) on their response to salt stress, and assess the efficacy of antioxidants (glutathione and ascorbic acid) in alleviating the harmful effects of salt stress on barley plants. Methods Barley grains were germinated and subjected to salinity stress, with subsequent treatment using glutathione, ascorbic acid, or an amino acid mixture. Growth criteria, photosynthetic pigments, metabolites, antioxidant enzymes, mineral content, and polyamines were analyzed. Results The impact of 100Mm NaCl, with or without glutathione, ascorbic acid, or amino acid mixtures, on various physiological parameters in G124 and G119 were investigated. The levels of chlorophyll a, chlorophyll b, and carotenoids significantly varied under different treatments. For instance, chlorophyll a in G 124 exhibited a 23% reduction under salt stress compared to the control, while the addition of glutathione mitigated this effect, resulting in a 17% increase compared to the NaCl treatment. Similar trends were observed for chlorophyll b and carotenoids. At the yield stage, both cultivars demonstrated a significant decrease in the the weight of grains per plant under salinity, which was alleviated by the addition of ascorbic acid, glutathione, or amino acid mixtures. Conclusion The application of glutathione, ascorbic acid, or an amino acid mixture mitigated the adverse effects of salt stress on various parameters. The results highlight the potentail of these compounds in enhancing plant tolerance to salinity stress and offer insights into the physiological response of barley cultivars under adverse conditions.

“…Amino acids are essential building blocks for the production of proteins, plant tissue, and chlorophyll. El-Shabasi et al (2005) discovered that treatments with plant-based amino acids considerably enhanced plant development and its constituent parts. El-Desouky et al ( 2011) on tomatoes and Abo Sedera et al (2010) on strawberries both reported similar effects and conclusions for plant-based and other essential amino acids.…”

In a greenhouse study on tomato, cucumber, and paprika, the effectiveness of TUVA product, a biostimulant and plant growth regulator manufactured from plant-origin amino acids used as organic fertilizer, was assessed. The goal of this study was to determine whether using the TUVA biostimulant, which is based on soybean and seaweed extracts and contains rich microelements essential for plant growth, can ensure good crop yield and quality in tomato, cucumber, and paprika plants growth and productivity. Over six months, the study was held in Mersin, Turkey, at three distinct sites. We looked at the physiological reactions of tomato, cucumber, and paprika plants that were grown in greenhouses and given TUVA biostimulant treatments. The use of the TUVA biostimulant increased plant height by 15% and biomass by 20%, as well as the number of fruits produced and total yield (up to 20.2%). The findings demonstrated that the TUVA product considerably improved all three crops' tonnage, homogeneous size, fruit quantity, and earliness. The fruits' quality was also improved by the TUVA product, which increased their marketability. The findings demonstrate a substantial positive correlation (R=0.9) between the TUVA product and each of the three crops' properties. The correlation coefficients further demonstrate the significant relationship (p ≤0.05) among variables. According to the trial's findings, the TUVA product has promise as a plant growth regulator for usage in greenhouse environments. It can considerably (p ≤0.05) increase the productivity and quality of tomato, cucumber, and paprika crops, and it is safe to use. According to the findings of this research, TUVA is a promising novel growth biostimulant that has the potential to enhance the performance of tomato, cucumber, and paprika plants cultivated in greenhouse environments. The methods by which TUVA improves plant development and productivity need more investigation, but the results of this study indicate that TUVA is a useful tool for producers who want to raise the yield and quality of their crops.

“…In this respect, it has been stated that foliar supplementation of AAs improves vegetative growth, quantity and quality in Solanum tuberosum (Mobini et al, 2014), garlic (El-Shabasi et al, 2005) and bean (Abdel-Mawgoud et al, 2011). In another publication, the foliar application of amino acid mixtures to broccoli seedlings significantly increased growth of the roots and shoots (Shekari and Javanmardi, 2017).…”

scientists are concerned about the utilizing of biostimulants-based amino acids in plant feeding and mitigating negative effects of water stress. As a result, two-year field experiments were conducted at Faculty of Agriculture's experimental station at Cairo University to study the effectiveness of liquid yeast waste (CMS) and Cargo amino acids (AAs) on the agro-physiological features of broccoli plants with different irrigation frequencies (every 5, 10, and 15 days). Compared with control plants, the foliar application of AAs and CMS significantly increased plant height, photosynthesis pigments, head weight, head diameter, head height, plant yield, and quality at different irrigation frequencies. Likewise, both treatments (CMS and AAs) significantly improved ascorbic acids by 16.65% and 15.95% and increased total phenol content by 24.10% and 36.60%, respectively, compared to control plants. Accordingly, the highest productivity was achieved for broccoli grown under irrigation every five days with the CMS bio-stimulant, where it was 3111.17 kg ha-1, while the lowest productivity was achieved for the control treatment in which no biostimulants were added and irrigation frequency every 15 days, and the productivity was 1376.22 kg ha-1. Plants irrigated every 15 days produced the highest levels of abscisic acid (ABA) and superoxide dismutase (SOD), followed by plants irrigated every 10 days and every 5 days. Exogenous application of amino acids bio-stimulants could be suggested to improve vegetative growth, biochemical characteristics, productivity, and nutritional value as well as to mitigate negative effects of water scarcity.
