【摘要】 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。更多还原

【Abstract】 This paper focused on the effect of temperature on the growth and pigment content of Betaphycus gelatinum 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 coincident with that of the pigment content, and the phycobiliprotein content was far higher than the chlorophyll content at different temperatures.更多还原
