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.

For cucurbit crops like cucumbers and melons, applying Ethephon during the seedling stage can increase the number of female flowers, thereby promoting more fruit production and increasing yield.
