摘　　要：考察了亚硒酸钠浓度对斜生栅藻(Scenedesmus obliquus)生物量的影响以及2.0 g/L亚硝基胍和不同紫外辐射照度胁迫对斜生栅藻中虾青素含量的影响。结果表明,斜生栅藻生物量随着亚硒酸钠处理浓度的增加而增加,其藻内虾青素含量随着紫外辐射照度的增加而增加,其中紫外辐射照度为0.6 W/m2时的虾青素含量比对照组提高了37.15倍,差异达显著水平(P<0.05)。Effects of concentration of sodium selenite on Scenedesmus obliquus biomass were studied. Effects of 2.0 g / L NTG and UV irradiance stress on onastaxanthin content of S. obliquus was investigated. The results showed that the biomass of Scenedesmus obliquus increased when the concentration of sodium selenite increased. The astaxanthin content of Scenedesmus obliquus increased when the UV-B irradiation dose of Scenedesmus obliquus increased. When UV-B irradiation was 0.6 W / m2,the astaxanthin content of Scenedesmus obliquus in the combined treatment group was 37.15 times higher than that of the control with the significant difference（P〈0.05）.
