The PSY1 Stem Psychrometer continues to be used in new and exciting applications around the world. Belgian researchers Prof. Kathy Steppe & Dr. Maurits Vandegehuchte who headed up an international team of researchers in Australia have used the PSY1 in ground breaking research in mangroves “Modelling reveals endogenous osmotic adaptation of storage tissue water potential as an important driver determining different stem diameter variation patterns in the mangrove species Avicennia marina and Rhizophora stylosa” Annals of Botany 2014 doi:10.1093/aob/mct311, and “Long-term versus daily stem diameter variation in co-occurring mangrove species: Environmental versus ecophysiological drivers” Agricultural and Forest Meteorology 2014 dx.doi.org/10.1016/j.agrformet.2014.03.002
Dr. Huade Guan and PhD students Yuting Yang & Hailong Wang at the National Centre for Groundwater Research and Training and Flinders University have recently built upon their great success in Australia using PSY1 Stem Psychrometers on Allocasuarina verticillata Examination and parameterization of the root water uptake model from stem water potential and sap flow measurements HYDROLOGICAL PROCESSES 2012 doi: 10.1002/hyp.9406 with a great new publication in which continuous and non-destructive water potential data collected using the PSY1 has been used to optimise canopy conductance models, “Optimization of canopy conductance models from concurrent measurements of sap flow and stem water potential on Drooping Sheoak in South Australia” Water Resources Research 2014 doi: 10.1002/2013WR014818 .
And Professor Mike Dixon and Newton Tran from University of Guelph in Canada are both presenting research at the International Horticulture Conference in Brisbane, Australia next week August 18th – 22nd 2014 detailing the use of the PSY1 stem psychrometers in the development of nursery irrigation management protocols, and the evaluation and certification of a Mycorrhizae soil amendment for reducing water stress of plants during drought. Measuring the efficacy of mycorrhizae in reducing drought stress in transplanted trees using automated stem psychrometers Both presentations will be available on the ICT International website following the conclusion of the International Horticulture conference on August 22nd 2014.
