Indoleacetic acid (IAA) fruit-set enhancer for tomatoes preventing cracking and doubling yield

Indoleacetic acid (IAA) is primarily used in tomato cultivation to promote seed germination, root growth, and fruit development, but potential risks should be considered.

1. Promote Seed Germination
Drenching seeds with indoleacetic acid (IAA) stimulates enzyme activity in tomato seeds, accelerating metabolism and promoting germination. However, the concentration should be controlled to avoid seedling deformities.

2. Promote Root Growth
By soaking the roots, indoleacetic acid enhances root vitality and improves transplant survival rate, making it suitable for tomato seedlings during the seedling raising stage.

3. Regulate Fruit Development
Spraying an indoleacetic acid solution during the flowering period can increase fruit set and reduce fruit deformities. It also promotes fruit growth and increases yield.
