Summary

Nitta, M., Tanaka, D. & Shirata, K. 2005. Exploration of a wild relative of Perilla crops, Perilla citriodora (Makino) Nakai, in Miyajima Island and the opposite shore, Hatsukaichi City, Hiroshima Prefecture.

In Miyajima Island, deer have increased so much, and their grazing has caused serious damage to vegetation in the whole island. However, the Perilla citriodora plants in Miyajima hardly seems to be grazed for a toxic substance of egomaketone contained as a major component of essential oil, whereas most plants of this species in Japan have citral other than egomaketone. For comparative studies of population structures using P. citriodora having different components of essential oil, we conducted exploration of this species in Miyajima and the opposite shore, Hatsukaichi city, where had been adjacent to Miyajima before marine transgression about 6,000 years ago. As results, no P. citriodora population was found except previous findings in Miyajima. Unfotunately, there was little time to search well in Hatsukaichi. The opposite shore needs further exploration, since specimen evidence has been found there.

Key words

  • Exploration, Essential oil, Perilla citriodora, Perilla frutescens, Perilla hirtella
