Indole Butyric Acid (IBA) is biology know as an role auxin that causes elongation of the cells of plant  stems, it is known as a plant hormone, that promotes growth and root formation.

Indole Butyric Acid (IBA) was shown to produce a higher yield of roots compared to the other auxins typically like Indole Acetic Acid (IAA) , 1-Naphylacetic Acid ( NAA) . and Auxins are known as common effects, stimulate rooting, berbacous woody ornamentalsand it is still subject to different corps tissue cultures, Rooting of plants grown in vitro is a very important moment of micropropagation. The main growth regulator used at this stage is auxin, which stimulates forming roots The most often used auxins are: (IAA), (IBA) and (NAA).

  • Used to stimulate rooting of cuttings for herbaceous and woody
  • ornamentals.  Used on adventitious root formation, such
  •  as tea tree, pepper,etc. 
  • It can promote fruit-setting, fruit-enlargement, yield-
  •  increasing, such as sugar beet, tomato, cornpotato.
  • It can promote sprout, seed-soaking, such as rice, cotton, potato, eggplant.
