TABLE 3.
Fine root morphology obtained from IGwl.
| Position | Treatment | Root diameter (mm) | SRL (m g–1) | RTD (g cm–3) |
| Top part | Control (n = 8) | 0.40 ± 0.02 | 37.3 ± 3.8 | 0.23 ± 0.01 |
| Partial-WL (n = 9) | 0.51 ± 0.02*** | 28.1 ± 2.1* | 0.23 ± 0.05 | |
| Bottom | Control (n = 10) | 0.44 ± 0.03 | 36.4 ± 3.9 | 0.22 ± 0.01 |
| part | Partial-WL (n = 9) | 0.53 ± 0.05 | 30.8 ± 4.3 | 0.19 ± 0.02 |
Mean (±SE) root diameter, specific root length (SRL), and root tissue density (RTD) obtained from IGwl (n = 8–10) of control and partial waterlogging (partial-WL). Values in black show results obtained from non-waterlogged soils, and values in blue show results obtained from waterlogged soils. Statistical difference was tested between treatments at the top part and bottom part, respectively. Results of one-way ANOVA are denoted as: *p < 0.05; ***p < 0.001. Results from full-WL are not shown as hardly any roots could be obtained from in-growth cores.
