Selected element-specific XRF images of a hydrated P. lanceolata root infected by the mycorrhizal fungus G. mosseae. The concentration ranges for the individual images are 0.03 to 0.87 µg cm−2 for Mn, 0.11 to 27.9 µg cm−2 for Fe, 0.03 to 1.55 µg cm−2 for Cu, and 0.04 to 4.98 µg cm−2 for Zn. The concentrations have not been corrected for small changes in the X-ray beam intensity or for the attenuation of the X-ray fluorescence by the sample, and may only be accurate to within a factor of two. |
