All aspects of tree growth and development are regulated by plant hormones and other growth-regulating substances. The most common of these compounds are the auxins, gibberellins, and cytokinins, but other substances such as ethylene and abscisic acid also have a significant impact on tree biology. Usually there is a complex interaction between the growth regulators to affect physiological responses. An understanding of plant growth regulators can significantly increase the capacity of arborists to effectively manage trees in urban landscapes. However, to effectively use plant growth regulators as a tool for tree management, arborists must understand the subtlety of their interactions. Furthermore, to achieve arboricultural objectives, arborists must also understand the nature of the biochemistry and importance of precise and targeted application of plant growth regulators. In an era of modern arboriculture practice, tree hormones and growth regulators are not just substances of control but tools of effective tree management.
