Plant growth regulators are substances that influence the growth and development processes in plants. They can affect various physiological processes such as cell division, elongation, differentiation, and even responses to environmental stimuli. By modifying these processes, growth regulators can promote or inhibit growth, control flowering and fruiting, regulate stem elongation, and influence the maturation of plants.

While flower color, leaf size, and pest resistance can be influenced by a combination of genetic and environmental factors, they are not the primary functions of plant growth regulators. Instead, these regulators are specifically designed to impact the overall growth patterns and developmental stages of plants, such as the timing of flowering and fruiting or controlling the size and shape of plants. This focus on growth and development distinguishes them from factors affecting flower color or pest resistance.
