Athyrium yokoscense can grow in the mine area such as copper. In Tokusima, it is grown at the old Hiroishi mine in the Kamiyama-cho. Athyrium yokoscense was analyzed on the each part such as leaf blade, petiol, rhizome, root. The average content of copper was in the order of the leaf blade<petiol<rhizome<root. There was much copper content in the spore following the rhizome. The spore of the plant needs nutrition for the germination. Athyrium yokoscense collected in greatly copper into the spore. The accumulation of copper by Athyrium yokoscense was compared in different areas of Hiroishi mine and Kasugataisya of Nara. The upper part of Athyrium yokoscense at Kasugataisya collects 0.05ppm copper. This comes from the reason that the average content of copper in the soil around Athyrium yokoscense was only 0.61ppm in Kasugataisya. When there are few copper it considers that there is little copper to accumulate in the root. It was compared with the place except for old Hiroishi mine about effect on accumulation of Athyrium yokoscense. Athyrium yokoscense growing in old Hiroishi mine had the amount of absorption of a 0.5-9.1times. Accumulation of copper by Athyrium yokoscense amounts to 3.5 times that in Hiroishi mine referring to that in Kasugataisya sample.
