摘  要:
采用Li-6400型便携式光合测定系统对自然条件下省沽油的光合特性进行研究。结果表明,省沽油夏季光合日变化呈双峰型,有明显的"午休"现象。其峰值出现在9:30和13:30。省沽油叶片的光饱和点为1 350μmol.m-2.s-1,光补偿点为43μmol.m-2.s-1,表观量子效率为0.062μmol.m-2.s-1。省沽油的光合特性表现为较耐荫的阳性植物。

摘  要:
We studied the photosynthetic characteristics of Staphylea bumalda under the natural condition using Li-6400 portable photosynthesis measurement system.The results showed that the curve of diurnal variation of photo-synthesis presented two peaks at 9:30 and 13:30 respectively in a sunny day with a remarkable noon inhibition.The light saturation and compensation points of Staphylea bumalda were about 1 350 and 43 μmol·m-2·s-1,respectively.The apparent quantum yield was 0.062 μmol·m-2·s-1,Staphylea bumalda is a heliophile plant of shade tolerance.
