Tryptophan is an important precursor of auxin biosynthesis in plants

Tryptophan is an important precursor of auxin biosynthesis in plants. Its structure is similar to IAA and widely exists in higher plants. Auxin can be synthesized by tryptophan in two ways: 1. Tryptophan was oxidized to deamination to form indole acetone, and then decarboxylated to form indole acetaldehyde; Indoleacetaldehyde is finally oxidized to indoleacetic acid under the catalysis of corresponding enzymes. 2. Tryptophan is decarboxylated to form tryptamine, and then oxidized by tryptamine to form indoleacetic acid. Tryptophan, as an essential amino acid to supplement plants, stimulates and regulates the rapid growth of plants, promotes the robust growth of plants and promotes the absorption of nutrients. Enhance the metabolic function of plants, improve photosynthesis, promote the development of plant roots, and accelerate plant growth and reproduction.

Effect of tryptophan as an essential amino acid supplement to plants

Early germination and high emergence rate: The application of amino acid humic acid can accelerate seed germination and improve seedling emergence rate, especially in early spring and low temperature (generally, it can germinate 1 ~ 3 days earlier and increase seedling emergence rate by 10 ~ 30%).

Fast absorption: Tryptophan in amino acid fertilizer can be directly absorbed by various organs of plants, passively absorbed or osmotic absorbed under photosynthesis. Obvious effects can be observed in a short time after use. At the same time, it can promote the early maturity of crops and shorten the growth cycle.

Strengthen physiological and biochemical functions: Tryptophan in amino acids can strengthen its physiological and biochemical functions after being absorbed by crops. Crops have strong stems, thickened leaves, expanded leaf area, accelerated formation and accumulation of dry matter, and crops can mature early. Due to their enhanced vitality, the performance of cold and drought resistance, dry hot wind resistance, disease and insect resistance and lodging resistance is improved, so as to achieve stable and high yield.

Promote plant photosynthesis: Tryptophan in amino acids can increase the content of plant chlorophyll, promote the absorption and utilization of carbon dioxide by crops, increase power for photosynthesis and make photosynthesis more vigorous.

Function of improving soil: Amino acid fertilizer has no residue in the fertilizer applied in the field, which can improve the physical and chemical properties of the soil, improve the water and fertility retention and air permeability, and play the role of curing, maturing and improving the soil.
