Propagation container (liner) | Liner imprintz (1–5) | Angle relative to horizontal of five largest diameter roots (degrees) | Total CSA of straighty roots |
---|---|---|---|
EP | 0.9 bx | 44 b | 1058a |
SM | 3.2 a | 52 a | 790b |
↵z1 = no visible deflection or retained “cage” formed by deflected roots at the position of the propagation liner; 5 = highly visible “cage” formed by deflected roots at the liner.
↵yStraight roots (>3 mm diameter measured at the edge of the dug root ball) were those that grew from trunk into landscape soil (following the largest at forks) without making a turn of more than 60 degrees relative to azimuth of the parent root at trunk; CSA calculated from diameter measured just beyond trunk.
↵xMeans in a column with a different letter were statistically different at P < 0.05; n = 36 averaged across 3.8 L and 9.5 L containers and root pruning; no interactions with 3.8 L and 9.5 L containers or root pruning were significant for these three attributes.
