Abscissic acid Explanation: The term ‘hormone’ was coined first by Starling (1906) in animal physiology. The internal factors that influence growth are called growth hormones or growth regulators as they inhibit, promote, or modify the growth. Growth promoters are auxins, gibberellins (GA), and cytokinins (CK). Growth inhibitors in plants are ethylene and abscissic acid (ABA).
