Differences between auxin analogues and plant grow

Some analogues of auxin belong to plant growth regulators, while others belong to a class of substances extracted from other plants and are similar to auxin.

The trace organic substances produced in plants that can be transported from the production site to the action site and have a significant impact on the growth and development of plants are called phytohormones, mainly including auxin, gibberellin, cytokinin, ethylene and abscisic acid. Phenylethyl acetate is also a substance with auxin effect in plants.

Plant hormone is an organic substance produced by plant metabolism. It moves from the production site to the action site, and has obvious physiological effects at very low concentrations. It is also known as plant natural hormone or plant endogenous hormone. Auxin analogues are artificially synthesized. The composition of growth hormone is indoleacetic acid. Indoleacetic acid is a chemical substance that promotes cell growth, with dual characteristics.

Plant growth regulators include synthetic compounds that have similar effects with natural plant hormones and natural plant hormones extracted from living things. Auxin analogues have similar physiological effects with plant auxin. They are synthetic chemicals, called auxin analogues, which are hormones that regulate the direction of plant growth produced by cell regions with division and expansion activities.
