Physical properties of four ring-porous hardwood species: Influence of wood rays on tangential and radial wood shrinkage [PDF]
, 2019 Some relationships between ray proportions, strength and shrinkage properties and basic density in hardwood species were highlighted. A better understanding of their relationships caused by the variation in moisture content in the hygroscopic domain ...

Sapwood area leaf area relationships for coast redwood [PDF]
Canadian Journal of Forest Research, 2005 Coast redwood (Sequoia sempervirens (D. Don) Endl.) trees in different canopy strata and crown positions were sampled to develop relationships between sapwood cross-sectional area and projected leaf area. Sampling occurred during the summers of 2000 and 2001 and covered tree heights ranging from 7.7 to 45.2 m and diameters at breast height ranging ...

Non-destructive estimation of sapwood and heartwood width in Scots pine (Pinus sylvestris L.)
Silva Fennica, 2010 Accurate estimates of the water conducting sapwood area are necessary to scale sapflow measurements to tree and stand level transpiration. We tested a non-destructive method, electric resistivity tomography (ERT), to estimate the area of conductive ...

Composition, distribution and supposed origin of mineral inclusions in sessile oak wood - consequences for microdensitometrical analysis [PDF]
, 2007 SEM and light-microscopical observations, supported by chemical microanalysis with an EDXA system, revealed that light-saturated pixels observed in X-ray negatives of sessile oak (Quercus petraea Liebl.) wood were caused by inorganic deposits present ...

Relevance of wood anatomy and size of Amazonian trees in the determination and allometry of sapwood area [PDF]
Acta Amazonica, 2019 Hydrological processes in forest stands are mainly influenced by tree species composition and morpho-physiological characteristics. Few studies on anatomical patterns that govern plant hydraulics were conducted in tropical forest ecosystems.

Daily variations of water use with vapor pressure deficit in a plantation of I214 poplars. [PDF]
, 2009 Daily rates of whole tree water use were measured in a homogeneous 7-year-old plantation over 84 days. Two trees were selected in the two most contrasting ends, i.e., with mean water table at -1.5 m and -3.5 m. Results showed that the mean tree water use

Variations in water use by a mature mangrove of Avicennia germinans, French Guiana [PDF]
, 2009 In the tropical intertidal zones, little is known on water uptake by mangroves. Transpiration rates are generally measured at leaf level, but few studies exist on water use at tree or stand levels.
