摘要
采用GFS3000光合作用测定系统及Junior-PAM荧光仪分别测定樟树不同方位叶片的光合特性及叶绿素荧光参数。结果表明:向阳面与背阳面叶片在8:00及12:00都有1个高峰值,其中12:00时达到一天中最大值,另外,背阳面叶片在16:00时还出现了1个小高峰。背阳面叶片Fv/Fm值明显高于向阳面叶片,但其净光合速率较向阳面的低。
The photosynthetic properties and chlorophyll fluorescence parameters of Cinnamomum camphora different range leaf were deter- mined with the GFS3000 portable photosynthesis system and Junior-PAM fluorescence spectrometer. The results suggest that： both the dayside and nightside leaves have a peak value at 8：00am and 12：00am, the maximum value appeared at 12：00am. In addition, the nightside leaves have a small peak at 4：00pm. The Fv/Fm value of the nightside is significantly higher than the dayside, but the net photosynthetic rate is lower.
