Phyto-IT co-authors a paper on Sap Flow Tool

Wednesday, November 11th, 2009

A paper on the use of Phyto-IT’s Sap Flow Tool, co-authored by Dirk De Pauw (Phyto-IT), has been published. This work was presented at the 7th International Workshop on Sap Flow which which was held in Seville, Spain from October 21th-24th 2008. The paper deals with the measurement, calculation and analysis of radial sap flow profiles.

Phyto-IT co-authors a paper on hydraulic redistribution

Wednesday, November 11th, 2009

A paper dealing with hydraulic redistribution in trees, co-authored by Dirk De Pauw (Phyto-IT), was published in New Phytologist. During a dry period, a 53-year-old Douglas-fir tree was subjected to localized irrigation on one side of the tree. This created heterogeneous soil water conditions which resulted in a stem-mediated hydraulic redistribution of the water to the other (non-irrigated) side of the tree. In addition, bidirectional flow in the dry root was also observed. This illustrates that water can simultaneously flow in opposite directions in the same part of a tree.
