摘　　要：研究了不同质量浓度花生四烯酸对雨生红球藻细胞生长和虾青素含量的影响。结果表明,适宜质量浓度的花生四烯酸（62.5 mg/L）能促进雨生红球藻细胞的生长,而低质量浓度（0.1~12.5 mg/L）和高质量浓度（312.5~1562.5 mg/L）的花生四烯酸均能抑制雨生红球藻细胞的生长;花生四烯酸能促进雨生红球藻虾青素的积累,随着花生四烯酸质量浓度的增加,雨生红球藻虾青素含量也逐渐增加,当花生四烯酸质量浓度为312.5 mg/L时,虾青素的含量最高,达3.67 mg/L,比对照组提高48.8%。The effects of arachidonic acid（AA）on the cell growth and astaxanthin content in alge Haematococcus pluvialis were studied in this paper.The results showed that an appropriate concentration of AA（62.5 mg/L）promoted the cell growth of the alga while low concentrations（0.1～12.5 mg/L）and the high concentrations of AA（312.5~1562.5 mg/L）treatments both restrained the cell growth of the alge.AA treatments promoted astaxanthin accumulation,with the increased AA concentrations,the astaxanthin content increased gradually,either.At the rate of 312.5 mg/L AA,the astaxanthin content reached its maximum（3.67 mg/L）.There was 48.8% higher in astaxanthin accumulation at 312.5 mg/L treatment compared with the control groups.
