摘要 用不同浓度的Na2CO3溶液模拟碱性盐胁迫环境,观察其对2个啤酒大麦品种种子萌发的影响。结果表明,随Na2CO3浓度增加,2个啤酒大麦品种的发芽势、发芽率、根数、根长、苗长、苗重下降,盐害指数增大。当Na2CO3浓度≥100 mmol/L时,完全抑制啤酒大麦根系生长;当Na2CO3浓度≤50 mmol/L时,能促进甘啤4号根数的增加。综合各个指标,在低浓度Na2CO3胁迫下,甘啤5号的抗性较好。 An experimental design using different concentration Na2CO3 solution to simulate alkaline salt stress simulation environment, to observed the effect of Na2CO3 stress on seed germination of two malting barley varieties. The results shows that the germination potential, germination rate, root number, root length, shoot length, seedling weight of two malting barley varieties decreased, salt injury index increased as Na2CO3 concentration increased, the beer barley root growth was completely inhibited at the Na2CO3 concentration ≥100 mmol/L; it can promote increasing of Ganpi 4 root number at the Na2CO3 concentration ≤50 mmol/L. Through all the above analyze, the resistance of Ganpi 5 is better at low concentrations of Na2CO3.
