Detailed explanation-1: -Auxins function primarily in stem elongation by promoting cell growth. Indole-3-acetic acid (IAA) is the major naturally occurring auxin and one of the major growth factors in plants. They were the first group of plant growth hormones discovered.
Detailed explanation-2: -So, the correct answer is ‘Auxin’.
Detailed explanation-3: -Gibberellins promote the formation of flowers on genetically plants in Cannabis whereas ethylene promotes formation of flowers on genetically plants.
Detailed explanation-4: -The plant hormone gibberellin (GA) controls major aspects of plant growth such as germination, elongation growth, flower development, and flowering time. In recent years, a number of studies have revealed less apparent roles for GA in a surprisingly broad set of developmental as well as cell biological processes.
