Table 4.
Biomass traits and % 13C recovered from the stem 30 h after labelling in three genotypes. N = 3 ± SE. Different letters show significant differences between genotypes according to an anova and associated t‐test. Values in parentheses in the % insoluble column show the additional results of t‐tests between the three genotypes (P =≤ 0.05)
