| 摘 要： | 以短枝型新红星幼树盆栽苗为试材 ,研究了水分胁迫对短枝型苹果叶片光合速率日变化的影响。结果表明 ,不同程度水分胁迫使光合速率日变化由单峰型曲线转变为双峰型曲线。轻度水分胁迫光合速率的日变化除与气孔因素有关外 ,还与非气孔因素有关 ;而中度、重度水分胁迫光合速率日变化主要与非气孔因素有关

| Abstract: | Effect of water stress on diurnal changes of photosynthetic rate in spur apple leaves were studied under pot cultivation in 1997～1998. It was found that water stress obviously changed photosynthetic rate diurnal curves. When“midday depression" occurred, the photosynthetic rate was limited firstly stomata, then by non-stomatic factors. |
