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 ...

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.

Sapwood hydraulic conductivity and leaf area – sapwood area relationships following thinning of aEucalyptus nitensplantation [PDF]
Plant, Cell & Environment, 2002 AbstractThis study tested the hypothesis that the relationship between leaf area (projected, or one‐sided) and sapwood area inEucalyptus nitens(Deane and Maiden) Maiden is affected by thinning treatment. However, no difference in the relationship between leaf area and sapwood area was found 8 years after thinning.
