| 摘要: |
| 通过多年田间试验，系统研究和分析了不同温型小麦叶片的气体交换等生理学特性。结果表明，不同温型小麦品种抽穗后叶片的净光合速率、蒸腾速率、气孔导度等生理特性表现出较明显的差异。其中冷型小麦品种的旗叶、倒二叶和倒三叶的平均净光合速率比暖型小麦品种分别高27. 63%, 40. 12%和70. 70%,平均蒸腾速率分别高21. 01%, 31. 54%及26. 50%,平均气孔导度分别高21. 09%, 33. 00%及19. 38%. |

|
| Abstract: |
| Based on perennial field experiments,leaf gas exchange character of differet temperature typal wheat was studied.The results indicated that there are clear differences of the leaf net photosynthetic rate,transpiration rate and stomatal conductance among differet temperature type wheat varieties after earing.The average of Pn,Tr and Cs of flag leaf,the second leaf and the third leaf of cool typal wheat are 27.63%, 40.12% and 70.70% for Pn; 21.01%,31.54% and 26.50% for Tr rate;and 21.09%;33.00% and 19.38% higher than those of warm typal wheat respectively. |
