The plants in Toyota district, Aichi Prefecture, which were suspected of Mn toxicity were studied from the viewpoint of the heavy metal interaction and from the microdistribution pattern of Mn in the leaf tissues as revealed by X-ray microanalysis. A high Mn/Fe ratio in the soils was found to be a decisive factor for the disorder in the plants. X-ray micrographs of affected field tea leaves showed that Mn was densely deposited in the epidermis, while no signs of Mn accumulation were observed in the palisade and spongy parenchyma and vascular bundle cells. The Mn distribution pattern in artificially Mn enriched leaves was found to be similar to that of the field grown Mn excess plant leaves. The deposited Mn in the epidermal cells of the artificially Mn enriched leaves was found to move easily when the leaves were dipped in water for 24 hr.
