Ion distribution in roots of barley seedlings measured by electron probe x-ray microanalysis.
The distribution of ions, particularly K and Na, was studied in roots of barley seedlings grown on various ionic solutions. Analyses were made by means of electron probe x-ray microanalysis using frozen, fractured bulk specimens. By this technique, it was demonstrated that there can be variability in the ratio K/Na measured in the vacuoles of cortical cells, with this ratio often being lower in...

15 صفحه اولThe Use of X-ray Microanalysis in the Study of Diffusion
This paper reviews the use of electron probe microanalysis, scanning electron microscopy and analytical electron microscopy in the measurement of compositional data obtained from diffusion couples. Methods to obtain x—ray spatial resolution as low as mm with the AEM are described. In addition, techniques for improving the detection and for increasing the accuracy of compositional analyses are s...
