Other claims from this paper (8)
- Observation Overall, the numerical values of α exceeded 1.0 for Phyllostachys edulis leaves.
- Association The scaling relationship between FM and A was statistically more robust than that between DM and A, for each age-group.
- Association Fresh mass (FM) increased linearly as culm age decreased.
- Association Leaf DM per unit area (LMA) showed a parabolic trend across the age-groups.
- Observation Diminishing returns is confirmed for all but one age-group.
- Association FM per unit A decreased with increasing age-groups.
- Association The middle age-groups had a greater LMA than the oldest and youngest age-groups.
- Association The age of shoots affects the scaling relationship between leaf mass and area.
