[The interaction of a root growing vertically with a rigid barrier].
Bending root tip that grows outside the soil is investigated. The decrease of growth rate due to increasing compressive stress leads to the destabilization of uniform solution, whereas differential growth that is controlled by root cap gravitropism is a stabilizing factor. The interplay of both processes leads to diverse behaviour types.
