CD BioSciences is committed to developing a variety of biophysical tools such as turgor probes to provide clients with a biophysical analysis of root growth under mechanical stress. We help our clients investigate the continuous impact of mechanical impedance on root growth, providing experimental data to support further understanding of root growth physiology.
In heterogeneous soils, the roots will experience a series of penetration resistances. The mechanical resistance has a direct and continuous effect on root growth, which in turn affects the development of the plant. There can be a complex and unique relationship between root elongation and penetration resistance. Therefore, we need to understand how the stress distribution around the roots varies between soil types and depends on the degree of radial thickening of the roots.
Much of the previous research has focused on obtaining detailed morphological and physiological information or the mechanics of soil compression around roots. Investigation of root growth under mechanical stress requires consideration of both the soil mechanics of root penetration and root growth physiology, which would bring new insights into the physiology of mechanically impeded roots. The rapid development of new technologies such as imaging, measurement and modeling techniques has contributed to the advancement of research in this area.

Research into the physiology of mechanically impeded root systems has lagged behind, due to the fact that the presence of physically impeded growth media makes it difficult to observe sample roots in situ. We have developed multiple biophysical techniques such as turgor probes and 3D imaging to apply to mechanically impeded root systems, providing our clients with powerful tools to analyze root growth under mechanical stress.
