| Abstract: | Photosynthetic characteristics were carried out with Doellingeria scaber,using the CIRAS-2 photosynthetic instrument.The results indicated that the light compensation points（LCP） and saturation light（SL） of Doellingeria scaber were 73.8μmol·m-2·s-1 and 1 115μmol·m-2·s-1,the apparent quantum yield of photosynthesis was 0.0147.The CO2 compensation points（CCP） and saturation CO2（SC） were 111.1μmol/mol and 987.5μmol/mol,the carboxlation efficiency was 0.0316.The optimum temperature for Pn in Doellingeria scaber’s leaves was 28.3℃. |
