| Dry biomass | Dry grain weight | WUEB | WUEY | |
| L-Δ13C | +0.260 (0.288) |
–0.129 (–0.124) |
+0.366 (+0.435) |
–0.155 (–0.144) |
| B-Δ13C | +0.625** (+0.733**) |
+0.312 (+0.513) |

L-Δ13C, leaf Δ13C; B-Δ13C, bract Δ13C. Values are Pearson correlation coefficients, + indicates positive correlation, – indicates a negative correlation, ** indicates significant correlation at the P < 0.01 level and the values in brackets indicate the correlation coefficient without considering MI treatment.
