Total phenotypic variation
Across all tissues measured, NSC concentrations were highest in branches (Clatskanie: 30.8 ± 8.3 mg•g-1, Corvallis: 30.3 ± 6.2 mg•g-1) and lowest in stems (Clatskanie: 15.6 ± 6.0 mg•g-1) (Table 1 & S2, Figure S1). The proportion of total NSCs in starch ranged from 0.10 ± 0.08 in branches in Corvallis to 0.28 ± 0.18 in roots in Clatskanie (Table 1 & S2, Figure S1).
