| 摘 要： | 研究结果表明,玉米在拔节期、子粒灌浆期中度、重度水分胁迫影响叶片的生长发育,对玉米的光合生理产生一定的影响。各水分胁迫处理复水后,存在明显的光合补偿现象。玉米在拔节期和子粒灌浆期中度以上水分胁迫处理,减产率在14.6%～24%之间。 |
| 关 键 词： | 玉米 水分胁迫 光合生理 产量 |

| Abstract: | The results showed that moderate and heavy water stress affected the growth of leaves and photosynthetic physiology at jointing stage and seed-filling stage of maize.There was obvious photosynthetic compensatory phenomenon after drought re-watering.The result showed that moderate and heavy water stress at jointing stage and seed-filling stage of maize would lead to 14.6-24% reduction of yield. |
| Keywords: | Maize Water stress Photosynthetic physiology Yield |
