How does ethylene affect cut flowers?

Ethylene is a naturally occurring plant hormone that plays a significant role in the ripening and aging processes of fruits and flowers. In the context of cut flowers, ethylene exposure leads to a range of responses that ultimately decrease the shelf life of the flowers. When cut flowers are exposed to ethylene, they typically experience accelerated senescence, which is the process of aging that can lead to wilting, loss of color, and eventual decay.

This is why it’s essential for florists and anyone handling cut flowers to minimize ethylene exposure by controlling environmental conditions and using products that inhibit ethylene's effects. Understanding the role of ethylene helps in extending the life of cut flowers, making it a critical aspect of floral care and display. While ethylene, in other contexts, can enhance fragrant qualities or even promote growth in certain stages, for cut flowers, its primary impact is detrimental, significantly reducing their longevity.
