Effects of NaCl Stress on Germination of Carrot Seed, Growth of Seeding and Structure of Leaf Cell

NaCl stress could distinctly inhibit germination of carrot seed,germination rate decreased half of that when the concentration NaCl was 50 mmol/L,and it decreased 82.9% when that was 150 mmol/L.NaCl stress always inhibited seedling growth no matter what the concentration NaCl was high and low,and made seedling growth amount,dry matter accumulation and water content to decrease effectively.The concentration NaCl largely effected on leaf cell structure,and karyon shinked,distorted or degraduated with rising of the concentration NaCl.
