Abstract
The seeds of hulless barley were presoaked with 5 different concentrations(0,25,50,75,100 mg/L) of salicylic acid(SA) for 12 h at 25 ℃,and then soaked in 250 mmol/L NaCl,aiming at studying the effects of salicylic acid on seed vigor and salt resistance of hulless barley.The results showed that NaCl stress decreased the seed germination and inhibited the seedling growth.25 mg/L and 50 mg/L SA presoaking could inhibit the decrease of seed germination rate,germination potential,germination index,vigor index,plant fresh weight,shoot dry weight,root dry weight of hulless barley,which were 48.00% and 28.00%,55.00% and 25.00%,60.52% and 35.42%,105.56% and 45.20%,28.03% and 7.22%,63.46% and 21.15%,39.29% and 10.71% higher than CK,respectively,and also alleviated the harmful effect of NaCl stress on plant height,root length and numbers.Higher SA could increase the inhibitory action of NaCl stress on the seed germination of hulless barley.This suggested that the suitable concentration of SA(25 mg/L in this study) could reduce the injury effect of NaCl stress on seed germination and enhance the seed germination activity of hulless barley under NaCl stress.
