Table 3.
The calcium (Ca), potassium (K), and iron (Fe) concentrations of 11 lettuce varieties evaluated in 3 development stages (microgreen, baby, adult). Values are the mean ± SE of four replicates per variety. The means were subjected to a one-way ANOVA analysis. Different capital and lowercase letters indicate significant differences between varieties and development stages, respectively, at p < 0.05 using the LSD test. DW: Dry weight.
