Consumption levels in parental strains and F1 hybrids of each nitrogen source.

Amount of nitrogen source consumed (mg/L), the relative percentage respect to the initial amount, its relative contribution to the total amount of nitrogen consumed and ANOVA statistical analysis in parental and F1 hybrid strains are shown. R1 and R2 represent each individual replicate, % Initial refers to the amount consumed respect to the initial amount provided and % YAN refers to the amount consumed respect to the total nitrogen provided. Av = average.
