14-Hydroxylated brassinolide can precisely act on each stage of plant growth: promoting root and seedling growth during the seedling stage, protecting flowers and fruits during the flowering stage, and improving quality during fruit enlargement, allowing crops to do the right thing at the right time.

In agricultural production, choosing the right plant growth regulators is one of the important means to increase yields and income. Below are some common and effective regulators and their main functions.

Natural cytokinins include:Kinetin (KT):Isolated from herring sperm cells in 1955, it was the first naturally discovered cytokinin.
Zeatin (ZT): Isolated from immature maize seeds, it stimulates cell division, promotes chlorophyll formation, accelerates metabolism, and protein synthesis.Dihydrozein (DHZ):Similar to zein, it is also a natural cytokinin.

Plant hormones and plant growth regulators precisely regulate crop growth, development, and stress resistance processes in modern agricultural production. Simultaneously, complex synergistic and antagonistic relationships exist between plant hormones and plant growth regulators, jointly regulating the entire plant life cycle.
