Responses of wheat photosynthesis and yield to elevated CO2 under heat and water stress
Future high CO2 world with increased heat and drought events threatens crop growth and production. Food security for the growing human population requires improved understanding of crop responses to extreme climate conditions.
My PhD project aims at combining FACE and glasshouse studies in order to develop mechanistic models that can incorporate crop leaf-to-canopy responses to stresses and their interactions with elevated CO2.
The main focus is to analyze the effects of elevated CO2 in combination with heat or water stresses on the photosynthesis and growth of field-grown (AGFACE, Horsham) and glasshouse-grown wheat lines, Scout and Yitpi. The physiological data will be used to model wheat productivity at elevated CO2 and interacting heat and water stress.
Outcomes of this research will fill a critical gap considering that currently used crop models lack a mechanistic approach based on physiology and stress effects. Project outcomes will help inform plant breeding and agronomic management strategies.
