Which Plant Hormone Retards The Growth Of The Plant?
Auxin is an important hormone that plays a role in the regulation of plant growth and development. It directs the processes of cell division, elongation and differentiation, embryonic development, root and stem tropisms, apical dominance, and the transition to flowering. What is the function of gibberellins?

Which plant hormone retards the growth of the plant? (2023)
Ethylene and Cytokinin Cytokinins regulate a wide range of growth and developmental processes throughout the life cycle of a plant, including seed germination, leaf expansion, induction of flowering, as well as flowering and seed development (Sun and Gubler, 2004; Yamaguchi, 2008).

Auxin and cytokinin are critical growth hormones in plant development and are naturally present within the plant at variable concentrations throughout the season. Their presence and activity are different from other hormones which act more in an on-off manner and are present only at specific times. Cytokinins regulate many cellular processes and stimulate cell division. Cytokinin is synthesized largely in root tissue and then travels upward to the shoots; some production also occurs in …

4.2 Plant Hormones – The Science of Plants – University of Minnesota
How plants respond to hormones. The five major groups of plant hormones — auxins, cytokinins, gibberellins, ethylene, and abscisic — acid are distinguished by their chemical structures and the response they evoke within the plant (see Table 4.1). For any cell to respond to a hormone it must be competent to perceive the chemical. Some cells simply lack the ability to see the hormone and do not respond to its presence. Competency to perceive a hormone depends on a cell’s physiology …

How hormones and growth regulators affect your plants
There are five groups of plant-growth-regulating compounds: auxin, gibberellin (GA), cytokinin, ethylene, and abscisic acid (ABA). For the most part, each group contains both naturally occurring hormones and synthetic substances. Auxin Auxin causes several responses in plants: Bending toward a light source ( phototropism ).

Plant Hormones and their Role in Plant Growth and Development
Plant hormones playa crucial role in controlling the way in which plants grow and develop. While metabolism provides the power and building blocks for plant life it is the hormones that regulate the speed of growth of the individual parts and integrate these parts to produce the form that we recognize as a plant. In addition, they playa controlling role in the processes of reproduction. This …

Growth Hormones in Plants | Actforlibraries.org
The different growth hormones work together to produce different manifestations of plants. Cytokinins and auxins are referred to as the two most important growth hormones of plants. Cytokinins and auxins are both necessary for the growth of shoots and roots. When cytokinins are high and auxin is low in a plant, shoots develop. If auxin is high and cytokinins are low, roots are formed. Auxins retard lateral bud development and cytokinins promote lateral bud development. Where auxins stimulate …
