Plant Growth Regulators are chemical substances that modify plant physiological procedures at very reduced concentrations. As opposed to fertilizers that give nutrients, PGRs work as signaling molecules to regulate growth patterns. They are often labeled into 5 important categories primarily based on their features:
Some PGRs are Obviously made by plants as internal messengers, while others are artificial compounds made to achieve certain agricultural or horticultural results. Understanding these regulators offers Perception into how plant growth is often precisely managed.
Chlormequat is used in crops like wheat, rice, and barley to reinforce stems and stop lodging. It enhances grain filling and uniform maturation, leading to much better harvests.
PGRs are very important for running plant peak, specifically in ornamental crops and cereals. Growth retardants inhibit stem elongation, creating more compact and durable plants considerably less vulnerable to lodging (slipping about) in adverse climate.
Comprehending the biology at the rear of hormonal steps combined with advances in technological know-how guarantees continued advancements in sustainable agriculture procedures exactly where plant proliferation is usually controlled precisely In keeping with human demands with out compromising ecosystem health and fitness.
Ethylene is unique among phytohormones as it exists inside a more info gaseous variety. It really is noted for its role in fruit ripening, accelerating maturation. Ethylene also influences leaf and flower senescence, resulting in their aging and shedding, and plays an element in breaking seed and bud dormancy.
Their role in optimizing crop production while reducing probable threats underscores the significance of proper administration and oversight.

Treatment must be taken to avoid root uptake when here dealing with plugs or recently potted crops with a substantial uncovered surface area place of expanding medium, by delaying application right until the plant’s foliage has read more coated many of the surface.
Application method PGRs could be utilized both as sprays or drenches, based upon their mode of action. Even though spray applications have a tendency to own a lot less influence on plant growth as compared to drenches, they are easier to good-tune by means of repeat applications.
Plant species Different plant species and kinds could vary in their reaction to the various PGR active elements.
Ethylene is a gaseous plant growth regulator answerable for fruit ripening and flower induction. Ethephon, a synthetic kind of ethylene, is commonly Utilized in agriculture.
Cytokinins are crucial for mobile division and differentiation, especially in roots and shoots. They hold off leaf getting older and boost lateral bud growth, influencing branching.
Spray applications are less costly to use than drenches because of the decreased labour expenses associated.
