Instead of developing a solid trunk, climbing plants use external objects as mechanical support while ascending towards the light. The climbing habit is widespread in the plant kingdom and various attachment systems evolved in different evolutionary lineages. Some species possess specialized roots or tendrils with adhesive pads allowing them to climb up flat surfaces. Methods used for analyzing the functional morphology and biomechanics of these attachment systems are presented. From the results of these investigations the functional principles of the attachment systems and the underlying hierarchical structuring can be identified. This knowledge might help to improve technical anchoring systems by applying biomimetic approaches.

Prof. Dr. Thomas Speck holds the chair for “Botany: Functional Morphology and Biomimetics” at the University of Freiburg. He is head of the Plant Biomechanics Group Freiburg, director of the Botanic Garden Freiburg and member of the board of directors of the Freiburg Centre for Interactive Materials and Bioinspired Technologies (FIT). His main research interests include biomimetics (esp. bio-inspired materials and surfaces as well as biomimetic applications to architecture); biomechanics and functional morphology of plants (incl. plant movements and plant animal interactions); evolution of plant growth forms and early land plants; and eco-biomechanics of plants in tropical rainforests.

Dr. Holger Bohn is a group leader in the Plant Biomechanics Group. His research interests focus on functional morphology and biomechanics of plant attachment, insect-plant interactions and carnivorous plants.

Stefanie Schmier is a PhD-student in the Plant Biomechanics Group Freiburg.
