设计了一套实验装置，研究了在浸水和裸露条件下，虫口珊瑚的光合作用、呼吸作用和钙化作用。试验结果表明：(1)水中的最大光合作用(Pgmax)是空气中的3.6倍；(2)光适应指标(Ik)在水和空气中没有任何差异；(3)水下和空气中的呼吸作用差异不显著；(4)空气中的光合作用-光照度(P-I)曲线的初始斜率(α)低于水中的P-I曲线；(5)空气中没有钙化。
An experimental set-up was designed to investigate photosynthesis, respiration and calcification of zooxanthellate scleractinian corals under submerged and exposed conditions. The results of experiments to determine the effect of exposure to air on the metabolism ofStylophora pistillata(Esper, 1797) revealed that: (1) maximum gross photosynthesis (pgmax) is 3.6 times higher in water than in air; (2) an indicator of photoadaptation (Ik) does not reveal any difference between water and air; (3) the difference between submerged and aerial respiration is not statistically significant; (4) aerial photosynthesis–irradiance (P–I) curves display lower initial slopes (α) than aquatic P–I curves; (5) there is no calcification in air.
