TWO‐DIMENSIONAL IMAGING OF ULTRA‐WEAK EMISSION FROM INTACT SOYBEAN ROOTS

Abstract

Abstract— Two‐dimensional imaging of photons emitted from soybean roots was achieved with an ultra‐high sensitivity photon‐counting image acquisition system. The detected images reveal that a soybean root itself emits very weak light and photon flux from the growing point of the root is more intense than that from other parts of the roots.
