The device for collecting root exudates from F. bidentis. The device was made of PVC tube (160mm diameter and 40cm height) and was divided into two parts. The plant grew at the top of the device (A). There is a hose (B), which is connected to a triangular flask (C), in the lower part. I was the control valve. During the growth, sterile water was poured in the top of the device (A) and the root exudates were collected in a triangular flask (C). We can also collect the remaining root exudates through hose (D), and the process was controlled by valve II.
