Calcium Content of Wheat Kernel Sections by Critical Microradiography.

Calcium segregations in thin sections of wheat endosperm were mapped by means of radiographs made with monochromatic X-rays whose wave lengths were on either side of the K critical absorption edge of calcium. Concentrations of calcium were observed within endosperm cell walls in some kernels, and generalized nonuniform distribution of calcium was observed in others.
