Exudation Pressure in Maple Trees: Comparing Simulations with Experiments
Exudation is the process whereby trees can generate a large positive pressure in stems or roots during months when the tree is leafless and mostly dormant and temperatures fluctuate above and below freezing. This article aims to provide an update on recent modelling efforts
in combination with experimental measurements from red/sugar maple trees at the University of Vermont Proctor Maple Research Center that validate the model results.
Preliminary Results of Sugar Maple Carbohydrate and Growth Response under Vacuum and Gravity Sap Extraction
Recent technological advancements have increased the amount of sugar-enriched sap that can be extracted from sugar maple (Acer saccharum). This pilot study quantified overall sugar removal and the impacts of vacuum (60 cm Hg) and gravity sap extraction on residual nonstructural carbohydrate (NSC) concentrations and on stem and twig growth.
