For propagation via cuttings, three types of auxin-based growth regulators—Indole-3-acetic acid (IAA), Indole-3-butyric acid (IBA), and Naphthaleneacetic acid (NAA)—offer the most outstanding overall rooting performance.

To effectively promote rooting, produce robust seedlings, and ensure high survival rates, rooting regulators used during the seedling stage must be precisely formulated based on crop type and propagation method, while adhering to standardized operational procedures.

Do not arbitrarily increase the dosage. Plant growth regulators are substances with physiological and biological effects similar to plant hormones; they must not be used in excess.

Plant growth regulators are categorized into three types: plant growth promoters, plant growth retardants, and plant growth inhibitors.
