| 摘 要： | 以抗虫棉品种为材料,研究了水杨酸(SA)对盐胁迫下棉花种子萌发和幼苗生长的影响。结果表明,在高浓度(>0.9%)NaCl下,棉花种子萌发受到显著抑制;在0.9%NaCl胁迫下,0.1~1.0 mmol/L SA均能够显著提高棉花种子发芽率和发芽势及幼苗的生长,并以0.5 mmol/L的SA处理对盐胁迫的缓解效果最好。研究认为水杨酸能缓解盐胁迫对棉花种子萌发和幼苗生长的抑制作用。

| Abstract: | In order to investigate the effects of salicylic acid(SA) on the seed germination and seedling growth of cotton under NaCl stress,the insect-resistant cotton seeds were used as experimental materials.The results showed that high concentration(>0.9%) of NaCl significantly suppressed the germination of seeds.Under 0.9% NaCl stress,0.1～1.0 mmol/L SA could obviously increase the quantity,speed and quality of seed germination.The optimum concentration of SA was 0.5 mmol/L.This experiment indicated that SA could reduce the inhibitory effects of salt stress on the seed germination and seedling growth of cotton. |
