Similar Relative Carbon Costs for Construction and Storage of Sun and Shade Branches in Mature Temperate Trees

Plant, Cell &Environment, EarlyView.
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

The legacy of past droughts induces water‐sparingly behaviour in Grüner Veltliner grapevines

Plant Biology, EarlyView.
Grapevines with a drought history showed increased water use efficiency in a non‐water‐limited season, in coordination with morpho‐anatomical modifications of leaf, xylem anatomy and stomata, suggesting significant drought legacies. Abstract Drought is becoming more frequent and severe in numerous wine‐growing regions.

Physical, Mechanical, and Thermal Properties of Heat-Treated Poplar and Beech Wood

BioResources
Air-dried density, weight loss (WL), impact bending strength (IBS), Shore-D hardness, and thermal conductivity values were determined for heat-treated poplar (Populus nigra L.) and beech (Fagus orientalis Lipsky) wood and compared with those for ...

Root overlap and allocation of above- and belowground growth of European beech in pure and mixed stands of Douglas fir and Norway spruce

Forest Ecosystems
Site conditions and species identity have a combined effect on fine root growth of trees in pure and mixed stands. However, mechanisms that may contribute to this effect are rarely studied, even though they are essential to assess the potential of ...

Turgor loss point explains climate‐driven growth reductions in trees in Central Europe

Plant Biology, EarlyView.
Leaf turgor loss point of native tree species shows a high predictive power over the observed growth anomalies in Central Europe during the extensive drought period between 2018 and 2020. Abstract As climate change thrives, and the frequency of intense droughts is affecting many forested regions, a mechanistic understanding of the factors conferring ...

Linking sap flow and tree water deficit in an unmanaged, mixed beech forest during the summer drought 2022

Plant Biology, EarlyView.
Sap flow and reversible stem shrinkage upon water depletion are strongly correlated under extreme drought conditions, but they respond differently to drought and cannot be used interchangeably when assessing tree response to drought. Abstract Temperate mixed forests are currently experiencing severe drought conditions and face increased risk of ...
