Effects of ΝaCl and SiO2 on plant height (cm), H2O2 (mol/g FW) MDA (nmol/g FW) and flavonoids (g CE./100 g DW) of the two tomatoes cultivars. Plant height, H2O2, MDA and flavonoids are the mean of 5 replications (plants); quality characteristics are the mean of 5 different measurements. Means in the same column followed by different letters are significantly different (P ≤ 0.05).
