摘要
以东风菜为试材,利用CIRAS-2便携式光合测定仪,对其光合特性进行研究。结果表明:东风菜的光补偿点、光饱和点分别为73.8、1115μmol·m^(-2)·s^(-1),表观量子效率为0.0147;CO_2补偿点、饱和点分别为111.1、987.5μmol/mol,羧化效率为0.0316;光合作用的最适温度为28.3℃。
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 CO_2 compensation points（CCP） and saturation CO_2（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℃.
