摘　　要：研究了4种植物生长调节剂对雨生红球藻细胞增殖、质量(干)、虾青素含量的影响。单因子试验结果表明,4种植物生长调节剂对雨生红球藻的细胞增殖在生长前期作用不明显,在对数生长期有明显的促进作用,质量(干)和虾青素含量有明显的增加;其中α-奈乙酸(NAA)、6-苄基嘌呤(6-BA)、2,4-二氯苯氧乙酸(2,4-D)、赤霉素(GA3)的最佳质量浓度分别为:0.5、0.5、0.1、0.5 mg/L。正交多因子试验结果表明:培养雨生红球藻添加6-BA、NAA和GA3的最佳质量浓度分别为0.5、0.1、0.05 mg/L。The effects of plant growth regulators on growth, dry weight and astaxanthin content of green alga Haematacoccus pluvialis were studied. The one-way experiment showed that 4 plant growth regulators NAA, 6 - BA ,2,4 - D and GA3had no significant influence on the multiplication of cells in the growth prophase of the alga, but had significantly improving effect on the growth, dry weight and astaxanthin content during the logistic growth phase. The optimal concentration of α-Naphthalene Acetic Acid （ NAA）, 6-Benzylaminopurine （ 6 - BA）, 2,4-Dichlorophenoxyacetic Acid （2,4 - D）, and Gibberellic Acid （ GA3 ） was 0. 5 ,0. 5,0.1 and 0.5 mg/L, respectively. Orthogonal test revealed that the optimal ratio of 6 - BA, NAA, and GA3 was 0.5,0.1 and 0.05 mg/L for Haematacoccus pluvialis culture respectivey.
