The results were summarized as follows:① The length and dried weight of shoot and the differentiation of leaves were enhanced on a culture medium with α-Naphthaleneacetic acid, and the effectiveness of NAA became stronger with the incerase in concentration within a range of 0.001 mg/L to 0.1 mg/L.

结果表明：①萘乙酸促进银杏茎尖伸长生长和叶片分化，随NAA浓度增加其作用增强，在NAA为0.1 mg/L时茎尖长度为对照的1.47倍，分化叶数为对照的2.62倍，茎尖干重为对照的6.45倍。
