Abstract
Plants have to cope with very different environmental conditions, which vary circadially enormously in most habitats, shaping daily patterns in physiological processes including long-distance water transport and xylem sap properties. The daily dynamics of physico-chemical properties of xylem sap and their covariation with tree hydraulic traits was investigated in hybrid aspen (Populus tremula L. × P. tremuloides Michx) in field conditions. The study provides new understanding on the environmental drivers that influence such dynamics.
