Table 1.
Characteristics for the branches used in the simultaneous NMR and neutron imaging measurements.
| Sample | Mean branch cross-section (mm2) | Mean xylem cross-section (mm2) | Phloem and bark cross-section (mm2) | Leaf area (cm2) |
|---|---|---|---|---|
| Pinon | 123 (±2) | 63 (±1) | 60 (±1) | 777.0 (±0.2) |
| Juniper | 93 (±1) | 65 (±1) | 27 (±1) | 996.4 (±0.2) |
The cross-sections were calculated assuming a circular branch cross-section. The representative diameter of each branch was obtained by averaging three pairs of measurements, taken along orthogonal axes, within the volume observed by the NMR coil.
