Commonly used ones include 2,4-D, 2,4,5-TNaphthalene acetic acid (NAA), Indole-3-Acetic acid (IAA), etc.  On citrus, 100-250 mg/kg2, 4-D treatment can effectively prevent the formation of the abscission layer at the fruit stem, keep the fruit stem bright green, prevent stem rot and black rot pathogens from invading the fruit, and greatly reduce rot .

6-benzylaminopurine (6-BA) is most commonly used in post-harvest fruit processing, especially for green fruits, which has outstanding antiseptic and green preservation effects.

Gibberellic Acid (GA3): 
Gibberellic Acid (GA3) inhibits the decomposition of chlorophyll in fruits and vegetables.  Treatment of citrus fruits delays the fading of chlorophyll, the appearance of carotene, and increases the hardness and thickness of the peel.

Ethephon is a substance that can release ethylene and is in liquid form.  In case of dilution or pH greater than 4, decomposition releases ethylene.  Spray or dip the bananas in the prepared solution, dry them naturally after treatment, and generally store them for 3 to 4 days before they mature.  Ethylene is used to remove astringency from persimmons.  Add 0.2% spreading agent to 250-500 mg/kg Ethephon solution and spray or soak the fruit.  It will take about 4 days to remove astringency and mature.
