研究了不同浓度的NaCl和Na2SO4对玉米杂交种子郑单958和丹科2162发芽的影响。结果显示,中低浓度的不同盐分均可以使玉米种子萌发,只有高浓度的盐分才能明显的抑制玉米种子萌发,但不同浓度的不同盐分都能显著抑制萌发种子的生长,并且NaCl对玉米种子萌发和生长的抑制要大于Na2SO4。盐分胁迫对丹科2162的影响要小于郑单958。
The effects of different concentrations of NaCl and Na2SO4 on the germination of Zea mays hybrids Zhengdan 958 and Danke 2162 were studied. The results showed that germination of maize seeds could be induced by different salt concentrations at medium and low concentrations. Only high concentrations of salt could significantly inhibit the germination of maize seeds. However, different concentrations of salt could significantly inhibit the growth of germinated seeds, And growth inhibition is greater than Na2SO4. The effect of salt stress on Danke 2162 was less than that of Zhengdan 958.
