Abscisic acid (ABA) is a plant hormone that acts as an inhibitor of growth and metabolism. It promotes dormancy, stomatal closure during water stress, and leaf senescence.

Plant hormones regulate various aspects of plant growth, development, and responses to environmental stimuli.

Auxins, Cytokinins, and Gibberellins are generally considered growth-promoting hormones, although their effects can vary depending on concentration and plant tissue. Ethylene is another plant hormone, often associated with fruit ripening and senescence, and can also inhibit growth in some contexts.
