2-Naphthoxyacetic acid (BNOA) is a synthetic auxin, a plant growth regulator used for control of preharvest fruit drop and promotes root proliferation. It was first mentioned in 1938 by Irvine.
|Mechanism of Action||
2-Naphthoxyacetic acid is linked to the dynamics of the plasma membrane, where it inhibits auxin influx.
|Plant Biology Applications||
2-Naphthoxyacetic acid is used to regulate growth of fruit crops including tomatoes, apple, grape, and strawberries.
2-Naphthoxyacetic acid has been used to induce somatic embryogenesis in grapevine (Vitis vinifera) from stigma and style explants and somatic embryogenesis was induced 3-7 months after culture initiation (Carimi et al, 2005). It can also promote seed germination and early flowering in tomatoes (Lycopersicon esculentum) (Singh et al, 2003).
