Effect of freezing stress on (a) K+ content and (b) Na+ content. The measurements were conducted in Fritillaria plants at days 7, 14 and 21 days after snowing (7, 14 and 21 DAS). Data are the means and standard errors of four replicates (n = 4). Data with different letters reveal statistically significant differences among the treatments according to a Duncan’s multiple range test (p < 0.05).
