About Plant Growth Hormones And Plant Growth Regulators

Both plant growth hormones and plant growth regulators have their respective roles in the growth and development of plants. As someone interested in agriculture, one should understand their importance to making the overall environment for plants safe and healthy. This article explores some essential information about these two variants - hormones and regulators related to plants. Please read on! 


Before we talk about regulators and hormones, let’s understand the factors responsible for plant growth. For a plant to withstand challenging conditions and grow in a favourable environment, it requires a proper amount of water, air, light, a consistent source of healthy nutrition, and a healthy temperature and sufficient space. 


The need for these growth stimulating factors differs greatly from one plant to another. A lack of one or more of these factors will become the limiting factor in plant growth. 


Organic compounds or hormones also play their roles in different plant stages - impacting the formation, controlling and regulating germination, growth and metabolism. So, what are plant growth hormones and regulators? 


Plant growth hormones are synthesised naturally by plants and are available at very low concentrations. On the other hand, plant growth regulators are applied by humans to plants. They refer to synthetic compounds that mimic the naturally occurring hormones in plants. Both hormones and regulators contribute to the growth and development of leaves, fruits, flowers, stems, roots, organs etc. 


More about regulators 


Plant growth regulators can be very helpful in plant growth. They can support crop planning, bring uniformity in plant shapes and sizes, and improve crop yield. The growth regulating substances are often applied to the plants using a spray or as liquid around the base of a plant. For the best results and to avoid consequences of overuse, they should be applied adequately following all the needed steps and procedures. 


The plant growth regulators can be divided into five types: Auxin, Gibberellins, Cytokinins, Ethylene, and Abscisic acid. Each has a specific job to perform. For example, Auxin can help take a plant (bend) towards a light source; it can promote the formation and development of fruits and flowers. In actively-growing plants, it can contribute favourably to cell growth and development. 


Cytokinins can stimulate the vision of plant cells and delay senescence. If a plant gets wounded, it can repair the affected areas using cytokinins and Auxin. On the other hand, Ethylene can impact the ripening and rotting in plants. Plant growth inhibitor Abscisic acid can promote the development of plant seeds and regulate leaf fall and dormancy.


Simply put, each of these regulators has its respective roles in the growth and development of plants. It is essential to understand which type of regulators will support a specific plant and accordingly use it.
