Explanation
Abscisic acid (ABA) is a plant hormone that plays a key role in inhibiting growth and promoting dormancy in plants. It is particularly known for its role in the abscission or shedding of leaves, flowers, and fruits, especially under stress conditions such as drought. This is why it is sometimes referred to as the 'stress hormone.' The other options relate to functions typically influenced by other hormones: the triple response is associated with ethylene, sex expression is influenced by gibberellins and ethylene, and flower initiation is promoted by gibberellins.
