New electrostatic theory for sap ascent in tall trees

Resumen

Objective: to propose a new electrostatic theory for sap ascent in tall trees.
Design/Methodology/Approach: we accomplished a detailed review of the different theories published
regarding sap ascent by capillary in trees. The new theory proposed herein is based on some scientific studies
of physiologists, biophysicists, and other branches of science, which expose the scientific bases of the water
movement in the plant, but who have not proposed an integrated framework.
Results: the proposed theory analyzed prior knowledge, then based on it, a new explanation is proposed for
the ascent of sap in trees.
Study Limitations/Implications: no field experiments were carried out to verify the increase in sap ascent
in trees with heights greater than 40 m.
Findings/Conclusions: this new theory helps to better explain water loss through transpiration and metabolic
processes, since both are closely related to the water content in the mobile solution in conducting vessels.
