Abstract
In this study, for establishment of method to quantitatively evaluate mechanical properties of growing roots including the driving pressure and Young’s modulus, we fabricated the microchannel device integrated with force displacement sensor. We used Arabidopsis thaliana, a model plant, and observed the root growth behavior by time-lapse observation. By analyzing buckling behavior of the growing root, we estimated the Young’s modulus of the growing root. It will be possible that this method contribute to the selection of soil with optimum hardness and nutrient concentration for various type of plants.
