Preferred Solution for Improving Crop Resistance to Premature Senescence — Peptides

Crop premature senescence is essentially caused by a decline in metabolic activity and protein synthesis capacity. As important intermediates in protein metabolism, peptides help maintain photosynthetic activity, sustain root vitality, and enhance stress tolerance, thereby effectively delaying crop senescence. MAX AMINO N16, developed by CityMax Group, is produced using advanced enzymatic hydrolysis technology and is rich in highly active peptides and amino acids, providing continuous nutritional and metabolic support during the later growth stages of crops. Leveraging its extensive expertise in proteins, peptides, and biostimulants, as well as its involvement in industry standard development, CityMax Group continues to drive innovation in peptide-based agricultural solutions.

Preferred Solution for Improving Crop Resistance to Premature Senescence — Peptides

Premature senescence is one of the major factors affecting crop yield and quality. Under conditions such as continuous fruiting, high temperatures, drought stress, and increased nutrient consumption, crops often exhibit leaf yellowing, reduced photosynthetic efficiency, weakened root activity, and accelerated aging, ultimately resulting in lower yields and poorer quality.

From a physiological perspective, crop senescence is essentially characterized by a decline in protein synthesis capacity and metabolic activity. As important intermediates in plant protein metabolism, peptides can rapidly participate in metabolic processes and provide continuous growth support, making them an effective nutritional tool for improving crop resistance to premature senescence.

1. Why Can Peptides Delay Crop Senescence?

• Maintain Leaf Functionality：Peptides promote the continuous synthesis of proteins and chlorophyll in leaves, helping maintain healthy green foliage, improve photosynthetic efficiency, and extend the functional lifespan of leaves.
• Sustain Metabolic Activity：Compared with inorganic nitrogen sources, peptides can more readily participate in nitrogen metabolism and protein synthesis, helping crops maintain vigorous growth throughout the season.
• Preserve Root Vitality：Root activity determines the plant's ability to absorb nutrients during later growth stages. Peptides help maintain root absorption capacity, ensuring healthy roots and prolonged leaf activity.
• Enhance Stress Tolerance：Under environmental stresses such as heat, drought, and low temperatures, peptides help maintain normal metabolic functions, improve stress resistance, and reduce stress-induced premature senescence.

2. MAX AMINO N16 — A High-Activity Peptide Nutrition Solution

To address premature senescence during the later stages of crop development, CityMax Group's premium plant-based enzymatically hydrolyzed amino acid product, MAX AMINO N16, provides excellent anti-senescence benefits by helping maintain crop vitality and delaying the aging process.

Product Specifications

Produced using advanced enzymatic hydrolysis technology, MAX AMINO N16 delivers a high concentration of amino acids while retaining abundant bioactive low-molecular-weight peptides. As a result, it not only supplies nutrients but also enhances plant metabolic activity.

For high-value crops such as tomatoes, peppers, watermelons, cucumbers, apples, grapes, and cherries, applying MAX AMINO N16 during the mid-to-late growth stages can help maintain leaf vitality, strengthen root nutrient uptake, delay plant aging, and support sustained yield formation.
