Bithell et al. Supplementary material
Supplementary material S1 Cultivar seedling heights (1997 seedling data set), nine year old grafted tree rootstock and scion trunk cross sectional area (TCSA) and relationships between seedling height and nine year old TCSA values, for 33 cultivars.
Table S1-1: Northern Territory (NT) accession codes and names of 33 rootstock cultivars, with results for 1997 seedling height (1997 seedling data set), and rootstock and scion trunk cross sectional area (TCSA) from 2006 when trees were 9 years old. Cultivar values are sorted by the scion TCSA rankings. The standard error of the mean (SEM), Tukey’s HSD value and P for the test of equal mean values presented. The 5 rootstock cultivars root sampled in 2010 are shown in bold.

Fig. S1-1: Plot of seedling height (1997 seedling data set) verses scion trunk cross sectional area (TCSA) in 2006 when trees were 9 years old for the 33 rootstock cultivars.
Supplementary material S2 Relationships between the height of rootstock seedlings (1997 seedling data set), vigour of orchard trees and root parameters for the five rootstock cultivars root sampled in 2010.
Table S2-1: Linear regression results for the a) height of rootstock seedlings for scion trunk cross sectional area (TCSA) of the rootstock and scion from 2006 and 2010 measurements, rootstock and scion TCSA growth rate (GR), root dry matter (DM) for four root size classes (Class 1 < 0.64 mm (C1); Class 2 0.64-1.88 mm (C2); Class 3 1.88-7.5 mm (C3); Class 4 7.5-23 mm (C4)) and total DM, root DM of each class and total DM relative to rootstock and scion TCSA and b) for orchard trees the 2010 TCSA versus root DM for each class and total DM, and TSCA growth rate for rootstock and scion versus class and total DM or the root DM of each class and total DM relative to rootstock and scion TCSA. Note: superscript stk/sc used to indicate variables that had values for both rootstock (stk) and scion (sc).
