The ratio of Na+/Cl- in roots was higher than that in leaves of two barley varieties with different salt tolerance under NaCl, Na+ and Cl- stresses of the same osmotic potential. Na+ content in leaves was lower and Cl- content in leaves was higher than that in roots. Ionic damage to plant cells under Na+ stress was greater than that under Cl- stress. The lethal Cl- content of leaf cells was 4.2-4.8 m mol/g. DW. Under NaCl stress, Cl- content in roots of the two varieties was about 20% of that in whole plant. Cl-content in roots and shoots of Tanyin No.2 was lower than that of Keping No.7 due to less Cl- uptake in Tanyin No.2
