Description

2-Naphthoxyacetic acid (BNOA) is a synthetic auxin, a plant growth regulator used for control of preharvest fruit drop and to promote root proliferation.  It was first mentioned as an active substance in 1938 by Irvine.

2-Naphthoxyacetic acid is soluble in ethanol, acetic acid, ether, and DMSO.  Slightly soluble in water.

Applications

    Plant Biology Applications

    2-Naphthoxyacetic acid is used to regulate growth of fruit crops including tomatoes, apple, grape, and strawberries.  It promotes seed germination and early flowering in tomatoes (Lycopersicon esculentum) (Singh et al, 2003).

    2-Naphthoxyacetic acid has been used to induce somatic embryogenesis in grapevine (Vitis vinifera) from stigma and style explants at 9.9 µM and somatic embryogenesis was induced 3-7 months after culture initiation (Carimi et al, 2005).
