Amino acid fertilizer for peppers and tomatoes

2.1 Best fertilizer for tomatoes and peppers on sweetening and coloring.

Amino acid special fertilizer for peppers and tomatoes is rich in arginine, tryptophan, proline, phenylalanine, tyrosine, and small molecule peptides required for plant on sweetening and coloring

2.1.1 The principle of sweetening and coloring:

1) Phenylalanine is a precursor for anthocyanin/flavonoid synthesis. Phenylalanine ammonia lyase (PAL) catalyzes the production of cinnamic acid, which activates anthocyanin synthase expression and accelerates pigment synthesis. Spraying grape skin with 0.1-0.5% phenylalanine increases anthocyanin content by 30-50%.

2) Tyrosine, as a substrate for polyphenol oxidase (PPO), catalyzes the production of quinones, promoting the synthesis of brown or red pigments, indirectly influencing the ethylene signaling pathway and accelerating the production of chlorophyll. Spraying 0.2% tyrosine during the veraison period increased carotenoid accumulation by 25%.

3) Proline maintains cell osmotic pressure, promotes the transfer of sugar to the fruit, eliminates reactive oxygen species, and protects the activity of sugar metabolic enzymes.

4) Glutamic acid promotes sugar conversion, synthesizes glutathione, and enhances antioxidant capacity;

5) Arginine promotes polyamine synthesis, stimulates ethylene production, and accelerates the hydrolysis of starch into sugars;

6) Tryptophan promotes vascular bundle development and enhances sugar transport capacity.

3.1 When should amino acid fertilizer for peppers and tomatoes be used to increase sweetness and color?

If your fruit isn’t turning color or sweetening well, try this amino acid fertilizer for peppers and tomatoes. Start using this fertilizer as soon as the fruit partially turns yellow or the base turns red. Combine it with a potassium fertilizer, or water-soluble fertilizer, and there’s no need to add or use other color-changing fertilizers. Visible results are visible after two applications. Data from our grape testing base shows visible results after about five days.

After using this product, the fruit becomes evenly colored, brighter, and sweeter, with enhanced aroma and flavor. These effects aren’t achievable with hormones, which only change color. However, this product improves aroma, sugar content, and overall taste. It contains no hormones or isomers, but only contains amino acids and trace elements that change color, preventing fruit softening or stunting.
