Project and Resarch Interests
My PhD project deals with the functional morphology of rosette plants. Especially the effect of morphological changes on light capture and thus physiology is investigated.
For this I create virtual three dimensional plants with the program YPlantQMC (Duursma et al. 2013) (based on Yplant (Pearcy & Yang 1996)). Combined with light simulation and photosynthesis models photosynthetic parameters can be determined from modified virtual plants. The evaluation of the YPlant program is another part of my thesis.
A special case of morphological changes can be observed in (heteroblastic) epiphytic bromeliads which show severe changes in leaf morphology in their lifespan.
