Analysis of variance of trunk diameter and bending stress required to pull trees to various trunk angles seven months after planting.
| Source of variation | Trunk diameter (cm) | Bending stress to 5 degrees (kN/m2) | Bending stress to 10 degrees (kN/m2) | Bending stress to 15 degrees (kN/m2) |
|---|---|---|---|---|
| Root pruning | nsz | ns | ** | ns |
| Irrigation | ** | ns | ns | ns |
| Root pruning × irrigation | ns | ns | ns | ns |
↵zMean (with S.E.) for the non-significant (ns) sources of variations.
Note: Asterisks (**) indicate statistically significant at P < 0.05.
