↵z Roots in the outer 3 cm in the north or south 180 degree circumference of root ball. Trees in #3, #15, and #45 containers for 7, 9, and 15 months, respectively.
↵y Measured at the position of the #3 container, before descending, circling, kinking, ascending, or growing straight into #15 substrate.
↵x See Table 1 for descriptions.
↵w Means in a column with a different letter are statistically different at P < 0.05; n = 10, averaged across root pruning treatment due to insignificant interaction (P > 0.20).
