Role of Biologically Active Amino Acid Formulations on Quality and Crop Productivity of Tea (Camellia sp.)

Influence of Amino Acids Mixture Application on Some Biochemical Aspects, Antioxidant Enzymes and Endogenous Polyamines of Vicia faba Plant Grown under Seawater Salinity Stress

“…The results recorded in Table 2 show that spraying faba bean plants with different amino acids mix concentrations caused significant increases in the concentration of FAA. Our obtained results are confirmed with those obtained by Abdul Qados (2009) on wheat plants, Thomas et al (2009) on tea plants, and Rady et al (2011) on sunflower plants. Thomas et al (2009) deduced that an amino acids application enhanced the uptake and accumulation of N elements to be involved in different biological processes leading to the formation of protective compounds, such as amino acids, against salt stress conditions.…”

Changes in the essential oil content and terpene composition of rosemary (Rosmarinus officinalis L.) by using plant biostimulants

“…Some authors reported that increased the soybean oil content was obtained by spraying with Kadostim (Toosi et al, 2014). Also, polyphenols and amino acid content in the tea plant by using of Aminolforte as bio-stimulant was increased (Thomas et al, 2009). Mehrabi et al, (2013) reported that use of Aminolforte, Kadostim, and Fosnutren in savory cultivation (Satureja hortensis L.) could increase the essential oil content.…”

“…Also, in plants the amino acids decomposed and intermediate metabolites formed and afterward, these metabolites will transform into glucose or are oxidized in the citric acid cycle (Miflin, 1993). Unlike sugars and fatty acids, the extra amino acids are not stored or disposed, but they are used as energy compounds (Thomas et al, 2009). In plants, amine group of the additional amino acids can be converted to urea and will be used as a nitrogen source.…”

“…In general, biostimulants are substances that stimulate plant metabolism and metabolic processes in order to improve plant growth (Starck, 2005). The base structure of biostimulants consists the mixture of various amino acids or their mixed with nutrition, hydrolyzed proteins, humic acid, seaweed extract and other ingredients (Gawronska et al, 2008;Thomas et al, 2009). …”

“…Besides facts mentioned above, amino acids can be mixed with nutrients, protein hydrolyzate, triacontanol, humic acid, seaweed extract and brassinolides and they are formulated as a plant biostimulants. A study found that indicators of physiological, biochemical and yield parameters in tea bushes were improved by spraying with Humiforte, Aminolforte, Kadostim, and Fosnutren as biostimulants (base formulation of this biostimulants is consisted from different amino acids which were combined with organic matters) (Thomas et al, 2009). Kadostim caused the increase of germination, root formation, accelerated the formation of leaves and reduced the effects of stress (Anonymous, 2014).…”
