  1. aThe concentration of the metabolites was calculated by dividing the area of each peak (corresponding to a metabolite) by that of the internal standard and then normalising it for the sample dry weight
  2. Different letters in a row indicate significant effects as evaluated by one-way ANOVA and LSD test (p < 0.05)
