Changes in metabolite profiles and antioxidative state in response to drought and high temperature stress in Douglas fir provenances

 

 

Climate change will lead to a temperature increase, change in precipitation patterns and an increasing frequency of extreme events such as drought, heat waves or storms. Future growth and productivity of forests depend on the adaptability, vulnerability, resistance or resilience of trees to future climatic conditions. However, the current understanding of adaptation and acclimation potentials of trees to climatic change is rather incomplete. Within their natural range, trees of the same species may grow under various different climatic conditions and these environmental differences act as selective force on the genetic and physiological growth response of the different provenances.

 

 

My PhD research on “Changes in metabolite profiles and antioxidative state in response to drought and high temperature stress in Douglas fir provenances”, aims to (1) study the metabolite profiles and antioxidant levels of different Douglas fir provenances; (2) evaluate the vulnerability of Douglas fir provenances to future climatic conditions and (3) detect physiological markers that can be used for the screening of drought tolerance of Douglas fir. Moreover I aim at understanding adaptations and mechanism to drought and high temperature stress in provenances of Douglas fir.
