What are the plant regulators to improve fruit quality?

There are many plant regulators to improve fruit quality, mainly phosphorus-containing fertilizers, such as potassium dihydrogen phosphate, and light cytokinin, which can adjust fruit quality and ripening time.

Cytokinin (CTK) is a plant hormone isolated or synthesized from corn or other plants. Generally produced in the roots of plants, it is a substance that promotes cytokinesis and promotes the differentiation and growth of various tissues. It has synergistic effect with auxin. It is a plant hormone that regulates the growth and development of plant cells. It plays an active role in cell division, and also participates in cell growth and differentiation and other related physiological activities, such as kinetin (KT), zeatin (ZT), 6- benzylaminopurine (6-BA) and so on.
