Study Notes
Plant Hormones
-
Auxins: Promote cell growth, stem elongation, root development, and prevent leaf drop.
-
Gibberellins (GA): Increase stem growth, trigger flowering, and break dormancy.
-
Cytokinins: Stimulate cell division and slow down leaf aging.
-
Abscisic Acid (ABA): Inhibits other hormones and assists the plant's response to water loss.
-
Ethylene: Accelerates fruit ripening and leaf detachment.
