Carbon balance and limitation of plant growth
Photosynthetic carbon assimilation is a fundamentally important process that provides the basis for all plant and animal life on earth. If photosynthetic carbon assimilation also determines plant growth and thus the provision of carbon-related ecosystem goods and services is a key question in plant and ecosystem ecology that remains yet to be resolved.
Our group investigates if and under which environmental conditions the supply of photosynthetically assimilated carbon determines a plant’s carbon-balance, carbon-allocation and carbon-usage. Specifically we seek to identify, if declining plant growth under drought or low temperatures is caused by a decline of assimilated carbon or if other physiological or developmental processes limit plant growth in such conditions.
