1-Methylcyclopropanecarbohydrazide is a precursor used to generate 1-methylcyclopropene (1-MCP), an ethylene perception inhibitor. It is applied primarily in agricultural and horticultural applications to regulate plant growth, delay senescence in fruits and flowers, and extend shelf life by reducing ripening and spoilage. Commonly used post-harvest on ornamental crops like cut flowers and potted plants to maintain freshness during transport and display. Also utilized to improve storage quality of fruits such as apples, pears, and bananas by preserving firmness, color, and reducing softening. The generated 1-MCP binds to ethylene receptors in plant tissues, making this compound valuable in commercial post-harvest management.
