The values followed by different letters are significantly different according to Duncan’s test at p ≤ 0.05; lowercase letters refer to the comparison between different genotypes and capital letters refer to the comparison between plant parts. Abbreviations: f.w., fresh weight; d.w., dry weight; TDS, total dissolved solids.
