| 摘 要： | 采用美国LI-COR公司生产的LI-6400便携式光合测定系统对青花椒坐果期的光合生理特性进行了研究。结果表明：坐果期青花椒的光饱和点为500μmol/（m^2.s）,光补偿点为55.59μmol/（m^2.s）;坐果期青花椒的光合速率日变化为单峰型曲线,峰值出现在11：00;青花椒叶片的气孔导度（stomacond）与叶片的光合速率日变化趋势基本一致,呈平行变化趋势,说明气孔导度是影响光合速率的直接因子。

| Abstract: | The photosynthetic physiological characteristics of Zanthoxylum schinifolium in fruiting period was researched by using the LI-6400 portable photosynthetic measuration system made by LI-COR company, USA. The results showed that the light saturation point and light compensatory point of Zanthoxylum schinifolium each was 500μmol/（m2^ ·s）and 55.59μmol/（m^2·s）. the day net photosynthetic rate changing was a single apex curve, appears at the 11：00 am. The net photosynthetic rate changed with the stoma cond together, it indicated that the cond was the main influence factor of net photosynthetic rate. |
