Values represent mean ± SD (4 × n = 25) % abnormal seedling production of cabbage and lettuce seeds exposed to deionised water (DW) and inorganic salt hydration treatments after CD. Values labelled with different letters are significantly different (p < 0.05, ANOVA) when compared across hydration treatments within each CD level. Cathodic water, CW; cathodic water adjusted to pH 6.5, CW (6.5); controlled deterioration, CD; abnormal seedling, AS; NS: not significantly different from value obtained with DW and therefore not considered in statistical comparisons.
