Plant growth regulators, including anti-gibberellins, are specific chemicals designed to influence the growth and development of plants. These substances can modify various physiological processes, such as cell elongation, germination, flowering, and fruit development. By applying growth regulators, arborists and horticulturists can enhance desirable traits or inhibit unwanted growth patterns, allowing for more precise management of plant health and aesthetics.

These regulators are especially important in commercial agriculture and landscaping where controlling plant size, timing of flowering, and fruit set can lead to improved yields and more manageable growth forms. For instance, anti-gibberellins inhibit gibberellin hormones that promote stem elongation, thereby helping to restrict growth in certain situations where excessive height or growth is undesirable. Understanding how to effectively use these growth regulators is essential for effective plant management and achieving specific horticultural goals.
