本试验研究了水杨酸（10（-2）mol/L、10（-4）mol/L、10（-6）mol/L和对照）浸种对小麦（Triticum aestivum L.）在盐度（8ds m（-1））和非盐度条件下。NaCl处理降低了小麦幼苗的出苗率、生长参数（地上部和根干重）、K+/Na+比值、渗透势和光合色素（Chla、B和类胡萝卜素）含量。在非盐胁迫下，水杨酸处理对出苗率无明显影响，但能提高幼苗地上部和根系干重、K+/Na+比值、叶绿素a、B和类胡萝卜素含量及渗透势。SA浸种处理提高了盐胁迫下小麦幼苗的出苗率、渗透势、地上部和根系干重、K+/Na+比值、叶绿素a、B和类胡萝卜素含量。这些结果表明，SA在盐碱和非盐碱条件下对植物生长都有积极的影响。但SA对盐胁迫下的出苗率、K+/Na+比值和渗透势的影响大于非盐胁迫下。
This study was conducted to determine the effects of seed soaking in salicylic acid (10(-2) mol/L, 10(-4) mol/L, 10(-6) mol/L and control) on the growth and some physiological characters in wheat (Triticum aestivum L.) under salinity (8 ds m(-1)) and non salinity conditions. NaCl reduced the emergence percentage, the growth parameters (shoot and root dry weight), K+/Na+ ratio, osmotic potential and photosynthetic pigments (Chl a, b and carotenoids) contents in wheat seedlings. The emergence percentage was not changed, in contrast, shoot and root dry weight of seedlings, K+/Na+ ratio, photosynthetic pigments (Chl a, b and carotenoids) contents and osmotic potential were increased by salicylic acid treatments under non salinity condition. Seed soaking in SA increased the emergence percentage, osmotic potential, shoot and root dry weight, K+/Na+ ratio, photosynthetic pigments (Chl a, b and carotenoids) contents in the salinity stressed wheat seedlings. These results were indicated that SA has positive effects on plant growth in salinity and non salinity conditions. But the effects of SA was higher on emergenge percentage, K+/Na+ ratio and osmotic potantial in salinity condition compared to non salinity condition was obtained in this study.
