Abstract
Real-time imaging analysis in a living plant allows studying the mechanism of chemical transport or signal transduction more in detail. We present the real-time autoradiography system to analyze the movement of β-ray emitters in a living plant. The system was consisted of a FOS (a fiber optic plate deposited with CsI(Ti) scintillator) and a GaAsP imaging intensifier unit. Though the resolution is about the same as that of an imaging plate(IP), the sensitivity was more than 10 times higher than that of an IP. Using this system, 32P movement in a young leaf of soybean was analyzed when 32P was supplied from the root.
