how to use pgr iba indol 3 butyric acid for rooting
Indole-3-butyric acid is a substance that is closely related in structure and function to a natural growth regulator found in plants. Indole-3-butyric acid is used on many crops and ornamentals to promote growth and development of roots, flowers and fruits, and to increase crop yields
How does IBA affect root growth?
A high concentration (10-7 M) of IBA inhibited root growth, evoked the development of apoplasmic barriers (Casparian bands and suberin lamellae) closer to the root apex, and elevated the amount of lignin in roots.
How do you mix indole-3-butyric acid?
Add 1.0 g of Indole-3-Butyric acid (IBA, GoldBio Catalog # I-180) to a 100 mL flask or beaker. 2. Add 2.0-5.0 ml of Ethyl Alcohol (EtOH) or 1N NaOH to dissolve the powder. Bring volume to 100 ml with molecular biology grade water.
Using aqueous IBA rooting solutions, spray onto the leaves until visually the droplets fall. Turn on misters after about 3/4 hr or until the solution dries on the leaves. Take care of cuttings. Total Immerse Method ™: Hydrate cutting
