In some species, it can trigger the transition from vegetative to reproductive growth, ensuring that flowering coincides with favorable environmental conditions. From seed germination to fruit ripening and response to stress, this simple two-carbon molecule coordinates complex developmental programs that determine crop yield and quality.

It antagonizes auxin in processes like leaf abscission and apical dominance, while synergizing with jasmonic acid and salicylic acid in defense responses. Flooding induces ethylene accumulation due to limited oxygen, leading to the formation of aerenchyma tissues that facilitate oxygen diffusion to roots.
Interaction with Other Hormones Ethylene does not act in isolation; its function is deeply integrated with other hormonal pathways. Growers use ethylene gas or ethephon sprays to synchronize fruit ripening for market readiness.

H2 Role in Fruit Ripening and Quality The commercial significance of ethylene function is perhaps best exemplified in climacteric fruits such as tomatoes, bananas, and avocados. These fruits generate a burst of ethylene during ripening, which initiates a cascade of biochemical changes including starch conversion to sugars, softening of cell walls, and development of characteristic color and aroma.
