The effects of CO2 concentration, nutrient levels, and irradiance on the growth of germlings and juveniles, and on the photosynthesis of adults were examined in a green tide alga, Ulva australis . We used a factorial experimental design with two CO2 concentrations (380 and 750 ppm), two nutrient levels (control and PES medium), and two irradiance levels (50 and 100 μmol photons m-2s-1). Germlings grew best (664.15±61.45 μm in length) under conditions of 750 ppm, PES, and 100 μmol photons m-2s-1 after 10 days in culture. Relative growth rates (RGR) of the juveniles were greatest (4.41% day-1) under conditions of 750 ppm, PES, and 50 μmol photons m-2s-1 after 5 days in culture. Photosynthetic efficiency (Fv/Fm) of the adult discs was 0.73 ± 0.05 before the experiment and reached a maximum (0.83±0.01) under conditions of 750 ppm, control, and 50 μmol photons m-2s-1 after 5 days in culture. Growth (germlings and juveniles) and photosynthesis (adult discs) of Ulva australis increased when CO2 levels were 750 ppm. Additionally, the optimal irradiance for growth and photosynthesis differed among stages, wherein germlings grew best at 100 μmol photons m-2s-1, juveniles grew best at 50 μmol photons m-2s-1, and adults photosynthesized most at 50 μmol photons m-2s-1. The performance of Ulva australis at all examined life stages was enhanced under the PES nutrient treatment. In conclusion, the physiological responses of U. australis to varying CO2, nutrient, and irradiance levels differed slightly among life stages. However, growth and photosynthesis always increased with elevated CO2 and nutrient concentrations. These results indicate that U. australis green tide blooms might occur more frequently in coastal areas if CO2 and nutrient concentrations increase.
Abstract
The effects of CO2 concentration, nutrient levels, and irradiance on the growth of germlings and juveniles, and on the photosynthesis of adults were examined in a green tide alga, Ulva australis . We used a factorial experimental design with two CO2 concentrations (380 and 750 ppm), two nutrient levels (control and PES medium), and two irradiance levels (50 and 100 μmol photons m-2s-1). Germlings grew best (664.15±61.45 μm in length) under conditions of 750 ppm, PES, and 100 μmol photons m-2s-1 after 10 days in culture. Relative growth rates (RGR) of the juveniles were greatest (4.41% day-1) under conditions of 750 ppm, PES, and 50 μmol photons m-2s-1 after 5 days in culture. Photosynthetic efficiency (Fv/Fm) of the adult discs was 0.73 ± 0.05 before the experiment and reached a maximum (0.83±0.01) under conditions of 750 ppm, control, and 50 μmol photons m-2s-1 after 5 days in culture. Growth (germlings and juveniles) and photosynthesis (adult discs) of Ulva australis increased when CO2 levels were 750 ppm. Additionally, the optimal irradiance for growth and photosynthesis differed among stages, wherein germlings grew best at 100 μmol photons m-2s-1, juveniles grew best at 50 μmol photons m-2s-1, and adults photosynthesized most at 50 μmol photons m-2s-1. The performance of Ulva australis at all examined life stages was enhanced under the PES nutrient treatment. In conclusion, the physiological responses of U. australis to varying CO2, nutrient, and irradiance levels differed slightly among life stages. However, growth and photosynthesis always increased with elevated CO2 and nutrient concentrations. These results indicate that U. australis green tide blooms might occur more frequently in coastal areas if CO2 and nutrient concentrations increase.
