Indole acetic acid, which is also known as IAA is the natural auxin which is present in plants. IBA, 2,4-D, etc are examples of synthetic auxins. On the other hand, gibberellin is also called as the gibberellic acid form which is notated as GA3. Zeatin is plant hormone which belongs to the family of phytohormones of cytokinin. It was first discovered in the corn kernels in Zea species. Dormin is the substance which has the ability to induce dormancy. Thus it is related to the abscisic acid, which results in the abscission of the entire plant. It causes dormancy of flowering buds, germination of seeds and so on.
