Indole-3-Butyric Acid (IBA) and 1-Naphthyl Acetic Acid (NAA) This combination is commonly used for cuttings or transplanted crops. For example, a 5% IBA·NAA soluble powder (containing 2.5% IBA and 2.5% NAA) can activate cell differentiation and promote root primordia formation

Zeatin promotes cell division and can affect other stages of the cell cycle. Its functions include inhibiting chlorophyll and protein degradation, slowing respiration, maintaining cell vitality, delaying plant senescence, reversing toxic effects on leaves, inhibiting root formation, and promoting shoot formation at high concentrations.

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.
