Sapwood Cuts and Their Impact on Tree Stability
Arboriculture & Urban Forestry, 2012 AbstractSapwood may be lost due to wood decay fungi or mechanical damage. Assessing the impact of sapwood loss on the likelihood of tree failure has not been empirically tested. The purpose of this research was to determine the effect of the loss of sapwood on the flexural stiffness of tree trunks for different species and trunk sizes.

HEM Tower - Sapwood Temperatures in Hemlock Trees
, 2011 Sapwood temperatures in four large hemlocks, 130-200 years old and about 40 to 90 cm basal diameter and 25 to 29 m tall, were measured in order to estimate sapwood respiration in these trees as part of a physiological model for hemlock forest carbon ...

, 2023 The cells in tree sapwood form a network of interconnected conduits which enables the transport of water and nutrients from the tree roots to the canopy. Sapwood depth must be assessed when tree water use is estimated from sap flow velocities.

New Phytologist, Volume 250, Issue 6, Page 3946-3960, June 2026.Summary Ectomycorrhizal fungi (EcMF) are key components of temperate ecosystems, and recent studies suggest that they can also inhabit non‐EcM plant roots as endophytes. We aimed to (1) provide new evidence of EcMF colonization of non‐EcM hosts, (2) offer direct microscopic confirmation of such endophytism and (3) assess factors influencing ...

Bayesian Approach to Sapwood Estimates and Felling Dates in Dendrochronology [PDF]
Archaeometry, 2002 An improved method of generating sapwood estimates for oak is developed. This suggests a revision of the 95% confidence range from 10–40 to 9–36 rings for trees from southern England. Current methods for estimating felling dates on timbers with incomplete sapwood do not generate true 95% confidence limits, and a Bayesian method for deriving such limits

Effects of heat treatment on the physical properties of heartwood and sapwood of Cedrus libani [PDF]
BioResources, 2013 Effects of heat treatment on the physical properties of heartwood and sapwood of Cedrus libani A. Richard, such as density, equilibrium moisture content, swelling, and fiber saturation point were investigated.

Plant, Cell &Environment, Volume 49, Issue 6, Page 3351-3362, June 2026.ABSTRACT Irradiance strongly affects the morphology, carbon (C) uptake and construction costs of leaves and branches. Within tree crowns, light decreases from the top downwards, but whether this translates to differences in the C balance of sun and shade branches remains unclear. Here, we combined a light‐driven photosynthesis model, parameterised with

A Comparison of Unbleached Pulps from Cherry Heartwood and Sapwood
, 1978 The purpose of the project was to evaluate pulps made from cherry heartwood and sapwood. The amount of heartwood a tree has is an individual trait of the tree rather than a function of geography or environment.

Physiological Entomology, Volume 51, Issue 2, Page 226-236, June 2026.Larval diapause intensity of Monochamus alternatus follows a declining curve, beginning with an initial refractory phase and reaching termination after approximately 110 days of chilling at 9°C. Residual inhibitory state strongly influenced post‐chilling development; additional chilling shortened the diapause period more at 18°C than at warmer ...
