| 中文摘要 | Photosynthetic responses of rewetted Nostoc flagelliforme to CO2, desiccation, light and temperature were investigated under emersed conditions in order to characterize its ecophysiological behaviour in nature. Net photosynthesis increased to a maximum rate at about 30 % water loss, then decreased, while dark respiration always decreased with the progress of desiccation. Light-saturated photosynthesis and dark respiration were significantly reduced at 8 degreesC, but remained little affected by changes of temperature within the range of 15-35 degreesC. Photosynthetic efficiency (alpha) was maximal at the beginning of desiccation and then reduced with increased water loss. Saturating irradiance for photosynthesis was about 194-439 mu mol quanta m(-2) s(-1), being maximal at about 30 % water loss. No photoinhibition was observed at irradiances up to 1140 mu mol m(-2) s(-1). Light compensation points were about 41-93 mu mol m(-2) s(-1). Photosynthesis of N. flagelliforme was CO2-limited at the present atmospheric CO2 level. The CO2-saturated photosynthesis increased with increase of irradiance (190-1140 mu mol m(-2) s(-1)) and temperature (8-25 degreesC) and decreased significantly with water loss (0-75 %). Photosynthetic affinity for CO2 was sensitive to temperature and irradiance. The CO2 compensation point (Gamma) increased significantly with increased temperature and was insensitive to irradiance. Desiccation did not affect Gamma values before water loss exceeded 70 %. Photorespiratory CO2 release did not occur in N. flagelliforme at the current atmospheric CO2 level. |
