| 摘 要： | ［目的］为筛选出龙须菜的最佳生长温度。［方法］测定了不同温度（15、20、25 ℃）对龙须菜生长和光合作用的影响，并根据海藻的生理活动与光合作用，研究了龙须菜影响温度变化的机理。［结果］25 ℃时，龙须菜具有最大的光合作用速率、呼吸作用速率、光能利用效率及光饱和点；20 ℃时，龙须菜具有最低的呼吸作用速率、光补偿点以及最高的R/P值。［结论］25 ℃是红藻龙须菜生理活动的最佳温度，20 ℃是龙须菜保种的最佳温度。

| Abstract: | Objective]The study aimed to choose the best growth temperature of Gracilaria lemaneiformis. Method]The effects of different temperature (15, 20, 25 ℃) on growth and photosynthesis of Gracilaria lemaneiformis were determined, and mechanism of temperature change acted on Gracilaria lemaneiformis were studied based on physiological activities and photosynthesis. Result]Gracilaria lemaneiformis had the highest photosynthetic rate, respiration rate, photosynthetic efficiency and light saturation under 25 ℃; the lowest respiration rate, light compensation point and the highest value of P/R were found under 20 ℃. Conclusion]25 ℃ was the best temperature for physiological activity of the thalli, 20 ℃ was the best condition for Gracilaria lemaneiformis storing. |
