What are the uses and properties of 1-MCP (1-methylcyclopropene)?
Aug 02,2026
1-Methylcyclopropene (1-MCP) is a small-molecule cyclic olefin with the chemical formula C₄H₆ and a molecular weight of 54.09. At room temperature, it exists as a colorless gas; it is chemically reactive and readily binds to ethylene receptors. Its primary mechanism of action involves competitively occupying ethylene receptor sites within plant cells, thereby blocking ethylene signaling and inhibiting ethylene-induced physiological responses. This characteristic makes it a highly effective inhibitor of ethylene action, holding significant value for applications in agriculture and horticulture.
What are the main uses of 1-Methylcyclopropene (1-MCP)?
1. Preservation of fruits and vegetables
Inhibition of ripening and senescence: By blocking the binding of ethylene to its receptors, 1-MCP delays the post-harvest ripening process of fruits and vegetables, preserving their firmness, color, flavor, and nutritional content. Examples include:
Apples: Reduces superficial scald and extends storage life to 8–9 months (compared to the traditional 3–5 months).
Kiwifruit: Maintains firmness, addresses the issue of short shelf life, and expands the transport radius.
Bananas, tomatoes, and strawberries: Inhibits respiration rates and ethylene release, reducing decay and weight loss.
Quality maintenance: Delays chlorophyll degradation, Vitamin C loss, and the decline of soluble solids, thereby preserving the commercial value of the produce.
2. Preservation of flowers
Extension of flowering period: 1-MCP inhibits ethylene-induced flower wilting, preserves petal color and fragrance, and extends the vase life of cut flowers.
Reduction of flower and fruit drop: In potted plants and ornamental flowers, it reduces bud, leaf, and flower drop, enhancing ornamental value.
3. Regulation of plant stress resistance
Disease resistance: By regulating reactive oxygen species (ROS) and phenylpropanoid metabolism, it induces the accumulation of disease-fighting compounds—such as total phenols and flavonoids—in fruit, thereby mitigating disorders like superficial scald and black heart.
Cold resistance: Enhances crop tolerance to low-temperature conditions and reduces cold injury.
Drought resistance: In crops such as cotton, wheat, and sugarcane, it enhances leaf water retention, reduces cell membrane permeability, and improves drought tolerance.
4. Field crop management
Drought resistance and yield protection: Under drought conditions, it prevents ethylene-induced leaf curling and the decline of photosynthesis, maintaining normal growth.
Prevention of fruit drop: Application before harvest reduces ethylene-induced fruit abscission, thereby increasing yield.
Application characteristics of 1-Methylcyclopropene:
High efficiency and low toxicity: At effective concentrations (typically in the ppm range), 1-MCP is non-toxic to humans and animals and has been approved for use in food preservation in many countries. Flexible application: Can be applied via fumigation, soaking, or spraying; suitable for cold storage, transportation, and field management.
Environmentally friendly: Degradation products are harmless, aligning with the development needs of green agriculture.
