| 摘 要： | 对夏季温室培养的鄂尔多斯高原碱湖的钝顶螺(节)旋藻(代号S1)和两个引进螺旋藻种(非洲乍得湖钝顶螺(节)旋藻(代号S3)、墨西哥Sosa Texcoco湖的极大螺(节)旋藻(代号S4)的光合速率、呼吸速率日动态变化规律进行了比较研究.结果表明:(1)在夏季晴天,温室中螺旋藻的光合速率日变化由于出现光抑制而呈双峰曲线,峰值分别出现在10:00时和12:00时;在夏季的多云和阴天状态下,温室中螺旋藻的光合速率日变化规律为单峰曲线.在不同天气状态下螺旋藻呼吸速率的日变化幅度较小.(2)3个螺旋藻样品的光合作用和环境因子分析显示,光强与螺旋藻光合速率之间在"午睡"情况下,呈显著负相关,在"非午睡"情况下,二者呈显著正相关(P<0.05);螺旋藻的呼吸速率随藻液温度的升降而升降,呼吸速率值S4S3S1.(3)3个样品光合产物的日积累量为晴天多云阴天.

| Abstract: | Comparative studies were conducted on the daily variation of photosynthetic rate and respiratory rate of Spirulina in greenhouse in summer among S.(A.) erdosensis,S.(A.) platensis and S.(A.) maxima.The species of S.(A.) erdosensis was grown in Inner Mongolia,while S.(A.) platensis and S.(A.) maxima were introduced species.The results showed that:(1) The daily variation of photosynthetic rate was a bimodal curve under the inhibition of HPFD in a sunny day,the peaks occurred at 10:00 and 12:00 respectively;wh... |
