%X 用单因素分析法研究赤霉素(GA)、6-苄基氨基嘌呤(6-BA)和吲哚乙酸(IAA)3种植物激素对长茎葡萄蕨藻生长、分枝数及叶绿素、粗多糖含量的影响. 结果表明： ① 0.8、1.4 mg·L-1的6-BA使长茎葡萄蕨藻质量相对增加率和比生长速率达到最大，11 mg·L-1为GA的最适使用浓度；IAA对长茎葡萄蕨藻质量相对增加率和比生长速率无显著影响；② GA、6-BA、IAA的最适促分枝浓度分别为14.0、0.4、5.0 mg·L-1；③ 不同浓度GA对长茎葡萄蕨藻叶绿素含量和粗多糖含量影响不显著，不同浓度IAA对其叶绿素含量的影响不显著，但对其粗多糖含量影响显著.<br>The effects of three kinds of phytophormones that gibberellin(GA)，6-benzyl aminopurine (6-BA) and indoleacetic acid(IAA) on the growth，the branch number，the content of chlorophyll and the curde polysaccharide of Caulerpa lentillifera have been studied with single factor analysis method. Research findings are shown as follows. First，0.8 and 1.4 mg·L-1 6-BA make the relative weight gain rate and the specific growth rate of Caulerpa lentillifera maximum. The concentration of 11 mg·L-1 is the optimum concentration of GA. IAA have no obvious effects on the relative weight gain and the specific growth rate of Caulerpa lentillifera. Second，optimal concentration for branch of GA，6-BA and IAA are as follows respectively: 14.0，0.4，5.0 mg·L-1. Third，different concentration of GA had no significant effects on the content of chlorophyll and curde polysaccharide. Different concentration of IAA also had no significant effects on the content of chlorophyll but curde polysaccharide
