Table 2.
Length (d) of the long and short axes of the elliptically shaped cross-sections of the conduits inside the major leaf vein in A. macrophylla and the number of conduits inside the vein at three different leaf zones (base, centre and tip). The potential hydraulic conductivity of the vein (Kh), approximated by using the conduit dimensions, is also shown
| Leaf zone | dLong axis (μm) | dShort axis (μm) | nconduits | Kh (m4 MPa−1 s−1) |
|---|---|---|---|---|
| 1 (base) | 30·1 ± 8·3 | 19·9 ± 6·6 | 53 ± 8·3 | 4·31 × 10−10 |
| 2 (centre) | 28·4 ± 2·9 | 20·1 ± 7·3 | 27 ± 2·9 | 1·96 × 10−10 |
| 3 (tip) | 11·6 ± 2·5 | 8·2 ± 2·2 | 10 ± 3·5 | 1·53 × 10−12 |
