摘要
通过对吴茱萸叶绿素含量、光合日进程等生理指标的测定,结果表明:吴茱萸较喜欢阴生;净光合速率日变化曲线为"双峰"型,光合速率上午快速上升到最大值后又逐步下降,主要由非气孔限制引起;吴茱萸叶片净光合速率(Pn)日变化与气孔导度(Cond)、二氧化碳浓度(CO2)呈正相关,与叶片温度(T1)呈负相关。
Chlorophyll content,diurnal variation and many other indicators of Evod iarutaecarpa were measured.The results showed that： Evod iarutaecarpa prefered shade;net photosynthetic rate curve showed as a ＂bimodal＂ type,photosynthetic rate quickly increased to maximum in the morning and then began to decline,mainly caused by non-stomatal limitation.Evod iarutaecarpa leaf net photosynthetic rate（Pn） on changes in stomatal conductance and（Cond）,concentrations of carbon dioxide（CO2） was a positive correlation;and leaf temperature（T1） was a negative correlation
