摘      要：With the spatial coherence of X-rays and high flux and brightness of the 3rd generation synchrotron radiation facility,X-ray phase contrast microscopy(XPCM)at Shanghai Synchrotron Radiation Facility(SSRF)can provide high resolution dynamic imaging of low electron density materials in *** this paper,we investigated the cavitation and water-refilling processes in rice and bamboo leaves utilizing XPCM at *** occurrence of xylem cavitation was recorded in *** study also revealed that under different dehydration conditions,cavitation occurs in different degrees,and therefore,the refilling process is *** results demonstrate that SSRF can provide high enough fluxes to study dynamic processes in plants in real-time,and XPCM is expected to be a promising method to reveal the mechanisms of cavitation and its repair in plants nondestructively.
