Discuss the hormones in plants and their actions. (auxin, gibberellin, cytokinin, abscisic acid, ethylene)
led by hormones. There are five major hormones: Auxin, Gibberellins, cytokinins, abscisic acid, and ethylene.Auxin affects meristematic growth, cell elongation in shoots, cell division, growth of late ... division, growth of lateral buds, production of xylem, development of fruits, and can help produce ethylene. Auxin causes the root to grow downward and shoot to grow upward. It's responsible for the ...
