Abstract: This paper focuses on the development of azimuthal root asymmetry in plant cuttings as a response to hydrodynamic forces. We aim to differentiate the effects that hydrodynamic forces acting on the plant cutting, stem, (dynamotropism) exert on root architecture from that of hyporheic flow (hydropatterning). Laboratory experiments were performed using Salix cuttings growing in quartz sand-filled rhizoboxes within a flume stream and undergoing different treatment conditions aimed at isolating hydropatterning from dynamotropism. We discuss the initial results of the experiments and provide first insights into various tropism responses, especially to dynamotropism.
