Agricultural production enhancer Indole Acetic Acid (IAA) shortens rooting time and increases fruit set rate

In citrus cultivation, treating the base of scions with a 0.3% Indole Acetic Acid solution can increase the grafting survival rate from the conventional 65% to 92%. Grape growers using a 50 ppm solution to dip cuttings have shortened rooting time by 5-7 days and increased the number of secondary roots by 3-4 times. For greenhouse-grown tomatoes, spraying with a 10 ppm solution during flowering increases fruit set rate by 18% while reducing the incidence of deformed fruit.
