Effects of indoleacetic acid: At the organ and whole plant level,
indoleacetic acid acts from seedling to fruit ripening.
Indole acetic acid controls reversible red light inhibition of mesocotyl elongation in seedlings;
when indole acetic acid is transferred to the underside of the branch, it produces the geotropism of the branch;
when indole acetic acid is transferred to the back side of the branch, it produces the phototropism of the branch;
Indole acetic acid causes apical dominance; delays leaf senescence;
indole acetic acid applied to leaves inhibits shedding, while auxin applied to the adaxial end of the abscission promotes shedding;
indole acetic acid promotes flowering, induces unisexual fruit development, delays shedding Fruit ripe.

Dosage |
1. Soaking:
(1) Soak the flowers with 3000 mg/L Indoleacetic acid liquid during the flowering period of the soaked tomatoes to induce parthenocarpy and fruit setting of tomatoes, form seedless tomato fruits, and improve the fruit setting rate;
(2) soak the roots to promote apple, peach , pear, citrus, grape, kiwi, strawberry, poinsettia, dianthus, chrysanthemum, rose, magnolia, rhododendron, tea, metasequoia, poplar and other crops to take root, induce the formation of adventitious roots, and speed up vegetative reproduction, generally 100-1000mg/L Dip the base of the cuttings, use a lower concentration for easy-to-root species and a slightly higher concentration for difficult-to-root species. The soaking time is about 8-24 hours, the concentration is high, and the soaking time is short.
2. Spray Chrysanthemum (under 9 hours photoperiod) with 25-400mg/L liquid spray once, which can inhibit the appearance of flower buds and delay flowering.
