Theoretical vs. measured root conductivity
| Species/depth | Measured Ks | Theoretical Ks | Percentage difference (%) |
|---|---|---|---|
| S. lanuginosum shallow | 9·5 | 24·9 | –61·8 |
| S. lanuginosum deep | 22 | 121·2 | –81·8 |
| Q. fusiformis shallow | 14 | 46·4 | –70·0 |
| Q. fusiformis deep | 43 | 197·4 | –78·2 |
Measured data are from McElrone et al. (2004).
Specific conductivity (Ks) values are in kg m−1 s−1 MPa−1. Vessel diameters used to calculate theoretical conductivity are presented in Supplementary Data Fig. S1.
