| 摘 要： | 采用Li-6400光合测定系统对扶桑幼树的光合特性进行了初步的研究．结果表明：扶桑叶片Pn13变化呈不对称的双峰曲线，最高峰出现在8：00，次峰出现在13：00．根据光响应曲线得出扶桑幼树叶片的光饱和点为1053μmol／m^2／s，光补偿点为29．55μmol／m^2／s．

| Abstract: | The photosynthetic characteristics of leaves in Hibiscus rosa-sinensis L. were studied with Li- 6400 portable photosynthesis system. The results showed that the diurnal changes of photosynthetic rate （Pn） in Hibiscus rosa-sinensis L. had double-peaks style and the maximum value of Pn appeared at 8：00 and inferior peak occurred at 13：00 respectively. According to the light response curve, a conclusion can be drawn that the light saturation point （LSP）and light compensation point （LCP） for the leaves of Hibiscus rosa-sinensis L. were 1053μmol/m^2/s/s and 29.55μmol/m^2/s . |
