Genetic variation of hydraulic and wood anatomical traits in hybrid poplar and trembling aspen
Download2011
Hacke, U.G., Schreiber, S.G., Hamann, A., Thomas, B.R.
•Intensive forestry systems and breeding programs often include either native aspen or hybrid poplar clones, and performance and trait evaluations are mostly made within these two groups. Here, we assessed how traits with potential adaptive value varied within and across these two plant groups....

Heterogeneous distribution of pectin epitopes and calcium in different pit types of four angiosperm species
Download2011
Intervessel pits act as safety valves that prevent the spread of xylem embolism. Pectin–calcium crosslinks within the pit membrane have been proposed to affect xylem vulnerability to cavitation. However, as the chemical composition of pit membranes is poorly understood, this hypothesis has not...

The main objective of the present study is to experimentally and numerical studies of hydrodynamic cavitation phenomenon in the Venturi tubes, in order to validate and further develop numerical multiphase flow models with the obtained data. To achieve this, a visible experimental set-up was...

Influence of Venturi Tube Geometry and Particle Properties on the Hydrodynamic Cavitation for Fine Particle Flotation
DownloadFall 2017
In this study, the influences of both Venturi tube geometry and particle properties on the hydrodynamic cavitation are investigated. In the geometry study, we investigated numerically and experimentally the influence of several geometrical parameters on the cavitation inception and bubble...

Luckert, Martin K., Armstrong, Glen W., Adamowicz, Wiktor L., Anderson, Jay A.
Previous studies suggest that management intensity zoning systems, such as the triad approach, could allow Canada’s forest industry to maintain or increase timber harvest levels while simultaneously reducing its environmental impact. In most such studies, the zones are exogenously specified. In...

The standard centrifuge method accurately measures vulnerability curves of longvesselled olive stems
Download2015
Venturas, M.D., Sperry, J.S., Hacke, U.G., Pratt, R.B. , Jacobsen, J.S., MacKinnon, E.D.
The standard centrifuge method has been frequently used to measure vulnerability to xylem cavitation. This method has recently been questioned. It was hypothesized that open vessels lead to exponential vulnerability curves, which were thought to be indicative of measurement artifact. We tested...

Two structure-function hypotheses were tested for vesselless angiosperm wood. First, vesselless angiosperm wood should have much higher flow resistance than conifer wood because angiosperm tracheids lack low-resistance torus-margo pits. Second, vesselless wood ought to be exceptionally safe from...
