| 摘 要： | 田间条件下对烤烟旺长期下、中、上部位叶片主要光合生理指标进行了测定。结果表明:3个部位的烟叶光饱和时光合速率与细胞间隙CO2浓度(Ci)饱和时光合速率比值(A350/Jmax)和光系统Ⅱ潜在活性(Fv/Fo)以中部叶最高,叶片气孔限制值(Ls)则以下部叶最高。不同烟叶部位之间叶片A350/Jmax、Ls、Fv/Fo的差异均达极显著水平;A350/Jmax与Fv/Fo之间呈极显著正相关,Ls与叶位之间呈显著负相关。 |

| Abstract: | The main photosynthetic physiology indexes of upper,middle and lower leaves of flue-cured tobacco during fast growing period in fields were analyzed.The results indicated that the middle leaves had the highest A350/Jmax and Fv/Fo,and lower leaves had the highest Ls.A350/Jmax,Ls and Fv/Fo of leaves of different stalk positions differed extremely significantly.There was an extremely significant positive correlation between A350/Jmax and Fv/Fo,and a significant negative correlation between Ls and stalk position. |
| Keywords: | Flue-cured tobacco Fast growing period Leaf Photosynthetic physiology index |
