Table 2.

Effect of salinity stress on K⁺/Na⁺, Pro, O₂^•−, and H₂O₂ in maize seedlings at different day intervals of stress treatments. Each value of data represents the mean of five replications (n = 5). Values within a column with different letters are signiﬁcant at p ≤ 0.05. Details are given in Table 1.
