| 摘 要： | 采用盆栽试验对不同土壤干旱条件下冬小麦幼苗蒸腾耗水特性进行了研究。结果表明,幼苗蒸腾速率、蒸腾耗水量、耗水系数均随土壤水分的减少而呈降低趋势。这说明,在干旱胁迫条件下,冬小麦幼苗通过减少蒸腾耗水提高水分利用效率,以适应干旱逆境。

| Abstract: | In this paper the characteristics of the transpiration water-consumption of winter wheat seedling were experimented under the condition of the different soil droughts.The results showed that transpiration rate,transpiration water-consumption,water use coefficient wene decreased with water-decreasing in soil.In a word,the decreasing transpiration water-consumption was a approach of winter wheat seedling adapting to soil drought and increasing water use efficiency. |
