Figure 4.

Estimated marginal mean of non-structural carbohydrate concentrations (mg g⁻¹ DW) (±SE, n = 12) of ‘Honeycrisp’ fruit sampled two months postharvest, as affected by rootstocks ‘G.41’, ‘G.935’ and ‘M.9-T337’, under Quincy (WA) growing conditions. From top to bottom: starch, fructose, glucose, myo-inositol, sorbitol, sucrose, and xylose. Different letters denote significant differences (Tukey’s HSD test, p < 0.050). Absence of letters for mean separation indicates non-significant differences.
