↵z Root cull according to Florida Grades and Standards for Nursery Plants (Anonymous 1998).
↵y Straight roots were those >1 mm diameter measured just inside the 3.8 L container sides that grew from trunk at <45 degree angle to substrate surface without making a turn of >60 degrees relative to parent root azimuth at trunk.
↵x Means in a column with a different letter are statistically different at P < 0.05; n = 16 averaged across 3.8 L container type due to insignificant interaction.
Note: Trees not root pruned when shifting to 3.8 L containers.
