“…These findings concur with those of [36] on basil plants, where it was discovered that foliar application of glycine increases the plant's wet and dry weight, leaf area, and total chlorophyll content, and with those of [37] on gerbera, who noted an improvement in the plant's vegetative characteristics when sprayed with glycine. Similar results were found by [38] when glycine was applied to the bean plant. The mineral nutrition with nano potassium had a positive effect in improving the vegetative growth of stevia plant due to the active role of potassium, as it activates most enzymes such as photosynthesis enzymes, oxidation and reduction enzymes, hydrogenation enzymes and energy enzymes.…”

Researchers from the College of Agriculture at the University of Kerbala in the Karbala province of Iraq used a greenhouse to examine the effects of nano-potassium and the amino acids tryptophan and glycine on the development of the stevia plant and the concentration of its active substances in the local climate. The experiment had three replicates and was carried out using a factorial trial design within a randomized complete block design (R.C.B.D). The study had three variables. The first component was tryptophan, with three concentrations (0, 25, and 50 mg. L-1), the second factor was glycine, with three concentrations (0, 500, and 1000 mg. L-1), and the third factor was nano-potassium, with two values (0, and 100 nmol L-1) (0, 2 g. L-1). The findings demonstrated that the variables under study, whether acting separately or in combination, significantly improved all characteristics of vegetative development. The triple interaction treatment (50 mg. L-1 tryptophan + 1000 mg. L-1 glycine + 2 g. L-1 potassium) gave the highest percentages for plant height, number of main branches, leaf dry weight, number of total leaves, and total chlorophyll content, where recorded (89.68 cm, 12.67 main branches. plant-1, 48.43 g. plant-1, 189.09 leaves. plant-1, 12,609 mg. 100 g-1 fresh weight, respectively). It may be concluded that the application of an integrated fertilization program can sustain or enhance stevia production in both quantity and quality under challenging environmental circumstances.

“…These results are in agreement with those obtained by Nahed and Laila (2007) who found that foliar application with tyrosine and tryptophan increased total free amino acids and chlorophyll on Salvia farinacea. Meanwhile Nahed et al (2010) reported that using of tyrosine at 200 ppm gave the best results in vegetative growth parameters .The highest values in vegetative growth parameters were obtained when plants were treated with tyrosine followed by tryptophan (Al-khawaga, 2014, Faissal et al, 2014, Al-Wasfy, 2014, Faissal et al, 2014Abd-Elkader et al, 2020.…”

T HIS study was achieved out during two successive seasons (2018 & 2019) on 12 yearold Red Roumy grapevines. The chosen vines were grown in a clay soil under surface irrigation system in a private vineyard at El-deer hamlet, Aga, Dakahlia region, Egypt. Three amino acids namely tryptophan, proline and tyrosine were used as foliar application at rate 100 and 200 ppm on the vines for three times, at vegetative growth start, at full bloom stage and at verison stage. Results appeared that using tryptophan, proline and tyrosine were effective in improving shoot length, leaf area, total chlorophyll and total amino acids in the leaves in addition percentages of N, P, K and Mg in the leaves as well as enhanced yield per vine, cluster weight, berry weight, berry set, SSC content, total sugars, total anthocyanin and total phenols, also enhanced pruning wood weight, ripening wood, internode length and thickness while reduced titratable acidity in berries as compared with control in two seasons. Application of tryptophan at 200 ppm and tyrosine at 200 ppm gave the significant highest of vegetative growth parameters, yield and its components. While, proline at 200 ppm increased SSC% and SSC acid ratio, total anthocyanin, total phenols and total sugars while these reduced titratable acidity. The best net profit of Red Roumy grapevines was obtained with tryptophan at 200 ppm.

“…Amino acids are involved in plant growth and development through the synthesis of proteins, phytohormone precursors and other organic compounds such as enzymes, amines, alkaloids and vitamins (Dinkeloo et al, 2018;Batista-Silva et al, 2019). Previous studies on ornamental cut flowers such as Gerbera jamesonii (Afifipour and Khosh-Khui, 2015), Polianthes tuberosa (Abd-Elkader et al, 2020) and Eustoma grandiflorum (Mondal et al, 2015) have shown that foliar applications with some amino acids increase the fresh and dry weights of leaves and roots, total leaf area, number of leaves plant -1 , chlorophyll (a, b and total), total carbohydrates, and leaf N, P and K contents.…”

“…Since substances or microorganisms exogenously supplied to plants, which increase growth, environmental stress tolerance or traits related to their commercial quality are considered bio-stimulants (Du Jardin, 2015), amino acids may be considered as such. Available data on the use of amino acids are abundant on vegetables (Haghighi and Barzegar, 2017;Moreira and Moraes, 2017;Wang et al, 2017;Khan et al, 2019), but scarce on cut flowers (Afifipour and Khosh-Khui, 2015;Geshnizjani and Khosh-Khui, 2016) and ornamental pot plants (Oliva et al, 2015, Abd-Elkader et al, 2020. Based on these data, active bio-formulations of amino acid mixtures from animal and plant constituents as bio-fertilizers have been developed and marketed during the last twenty years to improve horticultural plant growth, especially under abiotic-growth stresses (Hildebrandt, 2018;Batista-Silva et al, 2019;Salinas et al, 2019).…”

Amino acid solutions on the growth of the ornamental plant Impatiens walleriana grown under root restriction stress

et al. 2022

The use of amino acid solutions as bio-fertilizers was introduced in the food and ornamental plant industry about two decades ago. Sprays containing amino acids either alone or combined have been proven effective to increase plant growth. However, many of the new commercial solutions including amino acids as bio-fertilizers have no published data available on bedding plants. Thus, the aims of this study were to determine the changes in fresh weight accumulation in the bedding pot plant Impatiens walleriana and the physiological mechanism involved in plants sprayed with different amino acid solutions and to characterize the responses to root restrictions under nursery with non-limited nitrogen supply. The experiment was carried out inside a greenhouse in the campus of the Faculty of Agronomy of the University of Buenos Aires, Argentina. To reach the objectives, Impatiens walleriana ‘Xtreme White’ seeds were grown in 50-cell (55.7 cm3 cell-1) and 288-cell (6.18 cm3 cell-1) plug trays and then transplanted and grown at 3-L pots. Eleven solutions (100 mg L-1) containing an equal amount of each of the following amino acids: alanine, cysteine, aspartic acid, glutamic acid, glycine, leucine, lysine, methionine, threonine, tryptophan and valine, a control without amino acids, and a solution containing all amino acids (Mix) (9.1 mg L-1 of each amino acid) were sprayed when the first true leaf pair was developed. Our results showed that the different synthetic amino acids tested, alone or combined, had additive and antagonistic effects on the leaf area and fresh-dry weight in Impatiens walleriana plants.
