ypes and functions of plant growth regulators
Currently, the substances that have been found to regulate plant growth and development mainly include: Auxin, which promotes cell division and differentiation and increases fruit setting rate; Gibberellic Acid GA3, which promotes stem and leaf growth, balances nutrition, protects flowers and fruits, and makes fruits swell; ethylene, which breaks the dormancy of plant seeds and seedlings, promotes fruit ripening, and promotes leaf aging; Cytokinin, which promotes cytoplasmic division and lateral cell elongation; abscisic acid, which promotes leaf shedding and regulates the development of seeds and embryos; Brassinolide, which increases chlorophyll content, improves photosynthesis efficiency, promotes root growth, and protects flowers and fruits.

Indole-3-butyric acid (IBA) + Sodium α-naphthyl acetate
Spray seedlings with 10-20 mg/L concentration of indole-3-butyric acid (IBA) + Sodium α-naphthyl acetate or treat seeds with 10mg/L.
Chlormequat Chloride (CCC)
Spraying the leaves of seedlings with 100-500mg/L Chlormequat Chloride (CCC) solution can shorten internodes, thicken leaves and make them green, and resist drought and cold.

Triacontanol has a significant promoting effect on fruit trees, including promoting bud eye differentiation, improving fruit quality, reducing fruit drop, and increasing fruit color change and yield.

1. Harvest bananas that are 70% to 80% ripe, and use the dosage in the table. Soak them in Ethephon for 10 seconds on the same day, take them out and dry them, and seal them for storage.
2. This agent should be used immediately after preparation and cannot be stored. Use this product to soak the harvested bananas once.
