EcolChange seminar – Annika Meitern about the daily dynamics of aspen´s physiological traits

Seminar of Department of Botany and Centre of Excellence EcolChange

Annika Meitern is PhD student at the Department of botany.

Title of the talk: Daily dynamics of xylem sap properties and plant hydraulic traits in hybrid aspen

Time: Thursday, 16. November 2017 at 15.15

Place: Tartu, Lai 40-218 (Vaga auditorium)


Aspen´s sap (pic from here)


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.
