It has been used as a medium component for inducing somatic embryogenesis in grapevine. β-Naphthoxyacetic acid (BNOA) is a phytohormone used as a plant growth regulator on tomatoes and strawberries. 生化/生理作用：2-Naphthoxyacetic acid promotes seed germination and early flowering in tomatoes. 2-naphthoxyacetic acid effectively improves fruit size and color. However, it is also regarded slightly hazardous and may contribute to mutagenesis.
