Living on borrowed time – Amazonian trees use decade‐old storage carbon to survive for months after complete stem girdling [PDF]

open access: yes, 2018
Nonstructural carbon (NSC) reserves act as buffers to sustain tree activity during periods when carbon (C) assimilation does not meet C demand, but little is known about their age and accessibility; we designed a controlled girdling experiment in the ...

Da Vinci's mischief: xylem conduits in the stems of woody plants do not furcate

open access: yesNew Phytologist, EarlyView.
Summary The hydraulic architecture of plants is often modeled as a ‘furcating’ network, in which xylem conduits proliferate in number toward the stem apex, analogous to animal circulatory systems. Yet whether furcation actually occurs within woody stems remains untested, despite major implications for carbon costs and hydraulic efficiency.

The Durability of Teak Sapwood from Community Forest Treatened by Boron Compound though Lowry-Preservation Method against Subterranean And Dry-Wood Termites

open access: yesJurnal Ilmu Kehutanan, 2021
Nowadays, most of teak wood that available on the market was mainly from comunity forest. Those teak woods were commonly harvested in the early age. The young teak wood from community forests possesses lower proportion of heartwood than sapwood.

Tree crown architecture: a tool for decay resistance evaluation [PDF]

open access: yes, 2013
The variability of natural durability contributes to the bad perception of some wood end-users. In our search, we need to adjust our methods and strategies to estimate natural durability and extract higher value from wood resources.

Hydrological consequences of Eucalyptus afforestation in the Argentine Pampas [PDF]

open access: yes, 2005
The impacts of a 40 ha stand of Eucalyptus camaldulensis in the Pampas grasslands of Argentina were explored for 2 years using a novel combination of sap flow, groundwater data, soil moisture measurements, and modeling.

Thermo modification of Auxemma oncocalyx sapwood and heartwood

open access: yesAdvances in Forestry Science, 2021
The aim of this work was to analyse the effect of thermally modification of Auxemma oncocalyx (Pau-branco) sapwood, using two different temperatures, to obtain homogeneity between physico-mechanical properties and color of sapwood and heartwood. The physico-mechanical properties evaluated were basic density, luminosity of the color, dimensional ...

Can species adapt to drought using multiple strategies? Lessons from the California poppy

open access: yesNew Phytologist, EarlyView.
Summary Plants can escape drought by completing life cycles early, tolerate drought by increasing physiological limits, or avoid drought stress by obtaining or using water more efficiently. It remains unclear whether strategies vary within species across their distributional ranges due to trade‐offs, and whether species can exhibit plasticity in ...

The interplay between hydraulic capacitance and stomatal regulation strategy affects soil–plant hydraulics and transpiration

open access: yesNew Phytologist, EarlyView.
Summary Plant water storage contributes to transpiration, but it is unclear how its relevance in supporting transpiration depends on the stringency of stomatal regulation. Here, we show the compounding effect of stomatal regulation and hydraulic capacitance on plant water use, by means of a soil–plant hydraulic model and measurements of leaf water ...
