Plant hormones refer to trace organic substances naturally present in plants that have significant effects on plant growth and development. They are also called plant natural hormones or plant endogenous hormones. Its existence can affect and effectively regulate the growth and development of plants, including a series of plant life processes from cell growth and division to rooting, germination, flowering, fruiting, maturity and shedding.
Plant growth regulators are substances that have similar physiological and biological effects to plant hormones, which are synthesized artificially after people understand the structure and mechanism of action of natural plant hormones. They are used in agricultural production to effectively regulate the growth process of crops, achieve stable production and increase production, improve quality, and enhance crop resistance.
Plant growth regulators are artificially synthesized chemical substances that regulate the growth and development of plants and natural plant hormones extracted from organisms. They are called plant growth regulators.
