Phenotypic, genotypic, and environmental correlation coefficients (and their standard error) between TE and its components, water use and plant biomass (B).
| Traits | Experiment | Correlation coefficients | ||
|---|---|---|---|---|
| Phenotypic | Genotypic | Environmental | ||
| TEs vs. water use | 2 | −0.09 (0.07) ns | 0.72 (0.44) ns | −0.29 (0.08)* |
| TEs vs. water use | 2–3 | 0.05 (0.07) ns | 0.45 (0.22)* | −0.20 (0.11) ns |
| TEwp vs. water use | 3 | −0.09 (0.15) ns | 0.04 (0.31) ns | −0.21 (0.26) ns |
| TEs vs. Bs | 2 | 0.35 (0.06)* | 0.60 (0.24)* | 0.12 (0.08) ns |
| TEs vs. Bs | 2–3 | 0.45 (0.05)* | 0.63 (0.18)* | 0.28 (0.09)* |
| TEwp vs. Bwp | 3 | 0.31 (0.14)* | 0.34 (0.26) ns | 0.28 (0.27) ns |
Subscripts indicate whether these variables were calculated using shoot biomass (s) or whole-plant biomass (wp). Data corresponds to Experiments 2 and 3, or to the joint analysis of both experiments.
*
and ns indicate that correlation coefficients are significantly different or not significantly different from zero, respectively.
