| 摘要: |
| 以黄淮海地区5个主栽冬小麦品种为材料，在田间条件下分析了不同灌水次数对冬小麦叶绿素荧光特性的影响。结果表明，随着灌水次数的减少，叶绿素a+b（Chla+b）含量，叶绿素a/b，类胡萝卜素（Car）含量，PSⅡ最大光化学效率（Fv/Fm），光化学猝灭系数(qP)以及光能利用率（LUE）都呈降低趋势，而初始荧光（Fo）呈增加趋势，非光化学猝灭系数（NPQ）呈先增后降的趋势。不同冬小麦品种对灌水次数的生理响应不同，在各个灌水处理中光能利用效率较高的冬小麦品种矮抗58和郑麦366适宜种植的范围较广，在灌三次水处理(越冬水+拔节水+灌浆水)中光能利用效率较高而在灌两次水(越冬水+拔节水)或一次水(越冬水)光能利用率较低的冬小麦品种周麦18、豫麦49应该区划种植在水分条件较好或者有灌溉条件的地区才能发挥其品种的丰产优势。在干旱条件下矮抗58和郑麦366具有较高光能利用率的原因可能是有较强的光保护能力。 |

| Abstract: |
| A field experiment with five varieties of winter wheat in Huang-Huai-Hai region was carried out to evaluate the effect of irrigation amount on the chlorophyll fluorescence characteristics of flag leaf. The results showed that the reduction of the irrigation frequency resulted in lower chlo
rophyll a+b (Chla+b) content, chlorophyll a/b, carotenoids (Car) content, PSⅡ maximum photochemical efficiency (Fv/Fm), photochemical quenching (qP), and light use efficiency (LUE), while it increased the initial fluorescence (Fo). The non-photochemical quenching (NPQ) first increased and then decreased. Physiological responses of winter wheat varied with irrigation frequency. Aikang 58 and Zhengmai 366 were more adaptive to a broader range
of environments than Zhoumai 18 and Yumai 49 were, partially due to their high light use efficiency under different irrigation conditions. |
