Relationship between Na⁺ and K⁺ Contents in Shoots.

(A) Ratios of shoot Na⁺ and K⁺ contents of sas1 and wild-type plants cultivated in vitro for 12 days on standard medium and for 6 additional days on standard medium supplemented with 0, 20, 35, 50, 80, 100, 120, 150, or 200 mM NaCl.

(B) Na⁺ and K⁺ contents in aerial tissues of sas1 and wild-type plants in the culture conditions described in (A). Each point corresponds to one of the NaCl treatments. DW, dry weight.

For each measurement, the Na⁺ and K⁺ contents were determined for the shoots of an average of 20 sas1 (filled circles) or wild-type (open circles) plants. The error bars indicate standard deviation; n = 6.
