摘要/Abstract

摘要：

采用防雨池栽的方法,在花生苗期造成不同程度的水分胁迫,然后再正常供水,研究苗期水分胁迫对花生

产量、品质和水分利用效率的影响。结果表明,花生苗期水分胁迫可使荚果产量降低,籽仁蛋白质含量

提高,脂肪含量降低,油酸/亚油酸比值减少,耗水量减少；然而水分利用效率并不随耗水量的减少而降

低,苗期控水5 d处理的水分利用效率最高。苗期适度水分胁迫可提高花生的水分利用效率。

关键词: 花生；水分胁迫；产量；品质；水分利用效率

Abstract:

The method of pool culture in water proof installations was used to make various water

stress levels during peanut seedling stage. Afterwards, water was supplied normally. The

effects of water stress during seedling stage on yield, quality and WUE of peanut were

studied. The results indicated that water stress during seedling stage could decrease the

pod yield, increase the protein content of seed, reduce the content of fatty acid and the

O/L ratio. Thus, the water consumption reduced. However, the water use efficiency (WUE)

did not decrease along with the reduction of water consumption. Wilting 5 days treatment

at seedling stage could achieve the highest WUE. Moderate water stress during seedling

stage can increase peanut WUE.

Key words: peanut, water stress, yield, quality, WUE
