Outline of Final Research Achievements

Uranyl salts are effective to observe the cells of sections from plant pathology samples with much polysaccharides, but not to increase the contrast of cell walls, starch grains, glycogen particles and collagen fibers. Because of the radioactive salts, the use and purchase have been restricted only in Japan. The non-isotope heavy metals, positive to stain both the cell structures and the polysaccharides, are requested now. The staining effects of 5 different metals (SmCl3, SmAc3, GdCl3, GdAc3 and HfCl4) was examined ultrastructurally in cells of plant leaves and roots, insects, and fungi. Among them, GdAc3 and HfCl4 were excellent as positive electron stains whereas GdCl3 was good as a negative stain.
