为进一步提高海南琼枝麒麟菜(Betaphycus gelatinum )产量,本研究主要探讨了温度对琼枝麒麟菜生长及色素含量的影响。结果表明,温度对琼枝麒麟菜生长的影响比较明显,27℃时琼枝麒麟菜生长最快,随着温度的升高或者降低,琼枝麒麟菜生长率均降低,长期低于18℃或者高于36℃会造成琼枝麒麟菜的死亡。在27℃时琼枝麒麟菜含水量最低,干物质积累最快,即光合作用率最大。不同温度下琼枝麒麟菜色素含量与生长率变化趋势基本一致,其藻胆蛋白含量远远大于叶绿素含量。

This paper focused on the effect of temperature on the growth and pigment content of Betaphycus ge-latinum and provided useful information for promoting yield. The results showed that temperature had significant effect on the growth of Betaphycus gelatinum. It had a highest growth rate at 27℃ and the growth rate decreased both when the temperature increased or decreased. The B. gelatinum would die when the temperature was higher than 36℃or lower than 18℃.The dry matter content arrived at the peak value with the lowest miosture content at 27℃, indictive of the maximum photosynthetic rate. The trend of the growth rate of B. gelatinum is basically coin-cident with that of the pigment content, and the phycobiliprotein content was far higher than the chlorophyll content at different temperatures.
