Title
Improving power law fitting of root tensile strength–diameter relationships
G. J. Meijer Plant and Soil 2024. doi:10.1007/s11104-024-07007-9
Other claims from this paper (4)
- Method / resource Linear regression on log-transformed root strength measurements underestimates actual strength by 18% on average without a correction.
- Method / resource Fitting in terms of root forces at failure was less reliable than fitting tensile strengths.
- Recommendation Average power law fits were proposed for broadleaved trees, conifers, shrubs, grasses and forbs.
- Recommendation Power law curves should be fitted in terms of root strength rather than root forces at failure.
