(a) anti‐oxidant potential (b) mean stem length (c) mean stem diameter (d) leaf number index of the watercress accessions held within the germplasm collection. L1‐5 represent watercress accessions which had a low anti‐oxidant potential (<600 mmol Fe2+ per gram FW) whilst H1‐7 represent accessions with a high anti‐oxidant potential (>600 mmol Fe2+ per gram FW). Asterisks identify significance from two way ANOVA analysis *p < 0.05, **p < 0.01, ***p < 0.001. CE refers to the growth of the plants in a controlled environment in which environmental conditions are set to ensure minimum fluctuations and therefore any morphological or biochemical differences can be attributed to genes and not the environment.
