Definition
Ethylene is a gaseous plant hormone that regulates various physiological processes, including fruit ripening, flower wilting, and leaf abscission. It acts as a signaling molecule, influencing growth and development in response to environmental stimuli.
Summary
Ethylene is a vital plant hormone that plays a significant role in regulating various growth processes, particularly in fruit ripening and leaf abscission. As a gaseous hormone, it can diffuse through plant tissues, allowing for rapid signaling and response to environmental changes. Ethylene's influence extends beyond just ripening; it also helps plants adapt to stress conditions, making it crucial for their survival and development. In agriculture, ethylene is widely utilized to enhance crop production and manage the timing of harvests. Understanding ethylene's functions and applications can help farmers and horticulturists improve the quality and shelf life of fruits and vegetables. By learning about ethylene, students can gain insights into plant biology and the intricate hormonal interactions that govern plant life.
