What is the difference between plant growth regulators and plant hormones? Please introduce the concepts of plant growth regulators and plant hormones that are often confused. Plant hormone, which generally refers to plant endogenous hormone, is the product of normal plant metabolism, which can be moved from the synthetic site to the acting site to regulate the growth and development of plants and other physiological processes. Therefore, plant hormones are limited to trace active substances produced by specific parts of the plant in the process of normal metabolism. Plant growth regulators refer to some natural or synthetic organic compounds that are externally applied to plants and can regulate plant growth and development at low concentrations. Growth regulators include not only synthetic compounds that have physiological effects on plant growth and development, but also some natural compounds and plant hormones. Some of them can be extracted from plants, some mimic the structure of plant hormones, and some have no resemblance to plant endogenous hormones in chemical structure. When they are applied to the plant or applied to the soil and absorbed by the roots into the plant, they have the physiological activity of regulating plant growth and development. The types of growth regulators are: auxins, gibberellins, cytokinins, ethylene generating agents, growth inhibitors and so on.
