Effects of NaCl Stress on Growth and Physiological Characteristics of Celery Cabbage at Different Growth Stages

In the paper,we investigated the effects of NaCl stress on the growth and physiological characteristics of celery cabbage at different growth stages.The results showed that seeds and seedlings of celery cabbage were more sensitive to NaCl stress.100 mmol/L NaCl stress had no significant effect on the seed germination potential and germination rate,but it significantly reduced the germination index.And 100 mmol/L NaCl stress had no significant effect on the shoot fresh and dry weight of celery cabbage seedlings,but it made the root fresh and dry weight decreased significantly.Root activity decreased significantly and the content of MDA increased significantly under 150 mmol/L NaCl stress condition.The celery cabbage was not sensitive to NaCl stress with its concentration below 150 mmol/L at adult-plant stage.
