Other claims from this paper (7)
- Observation Plant component oxidative ratio ranged from 1.004 ± 0.010 in fine roots to 1.089 ± 0.002 in leaves in a beech forest.
- Observation Leaf and twig oxidative ratio differed between years and within years in the beech forest.
- Association Leaf and twig oxidative ratio showed no correlation with sampling height within the canopy.
- Observation Leaf oxidative ratio had the highest temporal variability, with minimum 1.069 ± 0.007 and maximum 1.098 ± 0.002.
- Association Low summer water availability in 2018 and 2019 could especially affect the August leaf oxidative ratio in beech.
- Observation Total above-ground oxidative ratio in beech showed little variation (1.070 ± 0.02) throughout the two sampling years, even under extreme events.
- Observation Stem oxidative ratio is extremely stable and dominates total above-ground oxidative ratio in beech.
