Plant Hormones- Natural Growth Regulators

Abstract

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.

Ascent and Attachment in Pea Plants: A Matter of Iteration

“…Another possibility may rely on the propagation of chemical signals such as the growth hormones (e.g., auxin, cytokinin) through the xylem (i.e., the plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant) and the phloem (i.e., the plant tissue that conducts sugars from the leaves to the other parts of the plant) [38][39][40]. Hormone propagations are responsible for maintaining the plant's nutritional and physical quality and for developing and growing the new organs in the plant's above-and belowground parts of the plant [40][41][42]. Further, they regulate plant growth in speed and direction of movement (e.g., active bending of the organs) [31,[40][41][42].…”
