摘要：

The monochromatic X-ray (37 keV) focused to microbeam (3 x 3 mu m(2)) with a Fresnel zone plate allows us for the first time to measure a cellular distribution of cadmium in the cadmium hyperaccumulating plant, Arabidopsis halleri ssp. gemmifera by detecting the Cd K alpha line. The distribution of cadmium in the leaves was clearly observed by in vivo monitoring. It was found that cadmium had highly accumulated in certain parts of the trichomes.
