Popis: Energy dispersive X-ray analysis of Ca and K was conducted in apple (Malus domestica Borkh.) leaves. Larger amounts of Ca and K were detected in the xylem than in the mesophyll tissue. The X-ray images of both the elements increased in intensities in samples from trees receiving gypsum and foliar sprays with CaCl2. Conversion of the X-ray images into graphical data produced a better quantitative comparison of element concentrations. The range of Ca concentration in the xylem of 206 to 350 ppm compared favorably with that reported in the literature for xylem sap of assorted tree species, including apple trees.
