Plant Hormones- Natural Growth Regulators

Plant hormones are compounds that can regulate the overall growth and development of plants and have a great influence throughout the lifecycle of plants. Various hormones act on the plant at different points of time depending on the vegetative or reproductive state of the plant. The effects of hormones on plants are quite complex to understand and a single plant hormone can have multiple effects on the growth and development of plants. They can help to regulate the homeostasis of plants under stress from both biotic and abiotic factors. Plant hormones have a very complex mode of interaction among themselves and how they influence plant development. There has always been more research done on understanding the individual plant hormone and their mechanism. More recent work focuses on complex problems like how different hormones work together to regulate the growth of plants. This mini-review article will focus on the five main hormones, their role in the growth and development of plants and their commercial uses in modern agriculture.
