Effect of root pruning in the nursery on container imprint ratingz of ‘Florida Flame’ maple planted in the landscape from #15 and #45 containers 49 and 34 months earlier, respectively.
| Root pruningy | Imprint rating on trees planted from #15 containers (1–5) | Imprint rating on trees planted from #45 containers (1–5) |
|---|---|---|
| Yes | 1.8 ax | 2.1 b |
| No | 3.0 b | 3.4 a |
↵z Container imprint rating ranged from 1 (no imprint) to 5 (high imprint), visually estimated by two observers individually.
↵y Shaving removed the outer 3 cm of the #3 and #15 root ball periphery and bottom prior to shifting into current container.
↵x Numbers followed by a different letter within columns are statistically different at P < 0.008; n = 24, averaged across container type due to insignificant interaction [P = 0.06 (#15) and 0.40 (#45)].
