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.

Fruit coloration is a key indicator of maturity; the surface color and the uniformity of this color largely determine the fruit's final market value and the farmer's economic returns. Farmers are keenly interested in methods to achieve safe, rapid, and uniform coloration, as well as enhanced sweetness and quality, to facilitate early market entry.
