Soil-root interactionSandy soils can be considered as granular materials. The packing porosity dtermines the efficiency of root development and its architecture. conversely the root growth modifies the surrounding packing of grains. The goal of our work is to study the coupling and feedback between root and its environment at different scales and with different experimental models.
- Chickpea root
- Chick-pea (Cicer arietinum L.) root growth inside the setup. We observe the evolution of the length and diameter of the root while growing inside the gap between the two photoelastic discs placed between circular polarizers. The evolution of the black fringe pattern is a way to measure the force exerted by the root during its growth. The different pictures are obtained from left to right, at 45 min after the experiment launching, 5.5 hours after, 10.25 hours after. The minimum gap between discs is 1 mm.
