摘要: 以抗旱性不同的5个大豆品种为材料,采用盆栽播种,分别在花荚期正常供水与水分胁迫条件下,测定了相对含水量、相对电导率、单株荚数、单株粒数、单株粒重、分枝数等与品种抗旱性相关的生理生态指标,并用隶属函数法对材料进行抗旱性综合评价。结果表明:品种综合抗旱性强弱为晋大73>晋大53>晋大52>晋大76>晋大75。

Abstract: The study was conducted in five soybean varieties with different drought resistance, which sowed in the pots. Lots of physiological and ecological indexes related to drought resistance in flowering-podding stage were measured in both normal and drought conditions. And a comprehensive evaluation on drought-resistance of different soybean varieties was given based on subordinate funtion values analysis .The results proved that the order of drought-resistance of different soybean varieties is JinDa73> JinDa53> JinDa52> JinDa76> JinDa75.
