In an era of increasing climate extremes and frequent soil stress, modern agriculture has entered a “high-resilience age.”

Drought, salinity, and heat stress are no longer rare occurrences—they have become recurring challenges that every grower must face.

Among all categories of biostimulant products, amino acid–based technologies are being redefined for their unique role in stress recovery and metabolic regulation.

Amino Acids: More Than a Nutrient Source

Traditionally, amino acids have been viewed simply as nitrogen supplements for plant growth.

In reality, they serve as signaling molecules, antioxidant precursors, and metabolic regulators that can “reactivate” the plant’s self-repair mechanisms at critical moments.

For example:

Under heat stress, plants accumulate proline and glutamic acid to maintain osmotic balance and mitigate membrane oxidation.

During salt stress, branched-chain amino acids (such as leucine and valine) help redistribute ions and alleviate sodium toxicity.

After chemical injury or transplant shock, amino acids rapidly restore carbon–nitrogen metabolism, accelerating tissue repair.

These mechanisms explain why amino acid–based biostimulants are becoming a cornerstone of modern agricultural resilience management.

CITYMAX AMINO Series: A Systematic Stress Recovery Solution

CITYMAX GROUP began developing amino acid–based biostimulant technology more than a decade ago.

The CITYMAX AMINO line integrates free amino acids, signal-type amino acids, and small peptides into a synergistic formulation that provides comprehensive support for crop stress recovery.

• Enriched with small-molecule amino acids 
• Optimized ratio of branched-chain to aromatic amino acids for flexible metabolic regulation.
• Fully compatible with humic acids, trace elements, and microbial inoculants, forming an integrated anti-stress management system.

“The true value of amino acid products lies not only in nutrition, but in keeping plants alive and active under stress.”

From “Stress” to “Restart”: The Core Logic of Recovery

The CITYMAX amino acid technology goes beyond supplying energy—it activates a three-tier mechanism of signal regulation, antioxidant protection, and metabolic reconstruction:

1. Signal Activation — Initiating Plant Defense

Amino acids such as leucine and arginine activate the TOR signaling pathway, redirecting energy and carbon–nitrogen flow to switch the plant from “stress pause” to “repair mode.”

2. Antioxidant Defense — Reducing Cellular ROS

Sulfur-containing amino acids (e.g., cysteine) act as precursors of glutathione and ascorbate cycles, lowering malondialdehyde (MDA) levels and preserving leaf integrity.

3. Metabolic Reconstruction — Restoring Energy and Balance

Amino acids replenish carbon skeletons for the TCA cycle, support energy metabolism, and modulate hormonal balance to promote new root and leaf growth.

The CITYMAX Advantage: Molecular Precision and Data-Driven Design

Unlike conventional hydrolyzed amino acid products, CITYMAX AMINO employs directional enzymatic hydrolysis and molecular-level screening to achieve precision performance:

• Retains only functional amino acids and peptides with molecular weights of 300–800 Da.
• Ensures that key active groups (proline, glutamic acid, glycine) account for over 80% of total amino acid content.
• Uses multi-layer filtration for high purity and excellent tank-mix stability.

Through years of global crop trials, CITYMAX has also established a comprehensive “Stress Factor–Amino Acid Type–Physiological Response” database, guiding precise formulation and timing recommendations.

Field-Proven Results: Repair and Performance in Harmony

Internal CITYMAX trials demonstrate significant efficacy:

• In tomatoes under salinity stress, AMINO-LQ reduced leaf MDA content by over 20%, increased photosynthetic rate by 15%, and improved fruit sugar content by 8%.
• In grape chemical injury recovery, Ultra AminoMax restored leaf turgor within 48 hours.
• In ornamental transplant trials, CITYMAX AMINO-TE combined with root drench achieved a 98% survival rate.

These results confirm that amino acids not only repair damage, but also activate potential.

Toward Sustainable Agricultural Resilience

CITYMAX GROUP believes that anti-stress management is not a one-time remedy, but a long-term, systemic regulation process.

When amino acids are applied together with biostimulants and microbial inoculants, they help rebuild the soil–root–leaf ecological chain, empowering crops with self-repairing capability under adversity.

This reflects CITYMAX’s enduring philosophy: “Stronger Crops, Sustainable Agriculture.”
