Plant cultivation. To visualize zinc dynamics in the whole plant body dwarf rice plants were cultivated. Seeds of the dwarf rice cultivar Oryza sativa L. cv Waito-C were germinated and each plant was grown in a vinyl pot (12 cm in diameter 10 cm height) filled with artificial soil (Bonsol Sumitomo Chemical Co. Tokyo Japan) in a greenhouse (15-h daytime) for 52 days.
