单色光对玫瑰茄悬浮细胞合成花青素的影响

玫瑰茄悬浮细胞合成花青素受光调节。将不同的单色滤光膜覆盖在摇瓶表面，控制光照强度，判定了蓝光是促进玫瑰茄细胞产花青素的最有效单色光；红光和橙光无效；其它单色光随其波长接近蓝光，正效应增强。单色光对玫瑰茄细胞培养过程的其它参数，如ｐＨ、降糖、细胞生物量等影响不大。

Monochromic effects on anthocyanin synthesis in roselle (Hibiscus sabdariffa L. ) cell suspension

The monochromic effects on anthocyanin synthesis in Roselle (Hibiscus sabdariffa L. ) cell suspension was studied by covering the agitated culture flasks with light-filter membranes. Through the spectrum of visible light, the blue light displayed the most significant and positive effect, under which the output of anthocyanin in 50 ml was more than 10 times higher than that under red light, orange light or darkness. Other lights with their wavelengths approaching that of the blue showed relatively more positive effects. Monochromic lights showed no obvious effects on the other parameters of the culture, such as pH, sugar residue, or biomass.
