Effects of NaCl Stress on Some Physiological Indices in Hulless Barley Seedlings

Effects of 200mmol/L NaCl stress on the relative water content, chlorophyll, malondialdehyde (MDA), proline contents was put under examination in hulless barley seedlings by means of nutrient solution culture. The results indicated that the relative water content (RWC) and chlorophyll content steadily sank down in hulless barley seedlings leaves at 2, 4, 6, 8d 200mmol/L NaCl stress, and chlorophyll content appeared a peak decrease after 4d stress. While the contents of MDA and proline went up strikingly. These results indicated that 200mmol/L NaCl stress had caused severe damage upon hulless barley seedlings.
