Useful:

• Chemical Classes: Pesticides -> Plant Growth Regulators
• Canonical SMILES: C1=CC=C2C(=C1)C(=CN2)CCCC(=O)O
• Uses: Indole butyric acid (IBA) is a broad spectrum indole-class plant growth regulators and is a good rooting agent. It can promote the cuttings and rooting of herbaceous and woody ornamental plant. It can also be applied to the fruit setting of fruit as well as improving the fruit setting rate. Used to stimulate root formation of plant clippings. Suitable for plant cell culture tested. Indole-3-butyric acid is auxin-family plant hormone (phytohormone). IBA is thought to be a precursor of indole-3-acetic acid (IAA) the most abundant and the basic auxin natively occurring and functioning in plants. IAA generates the majority of auxin effects in intact plants, and is the most potent native auxin.
