Abstract

In order to artificially increase the contents of essential oils from 4 different trees by inducing with elicitors, 5 kinds of chemical elicitors and 4 kinds of biotic elicitors were selected. Before treatment, the contents of essential oils from Japanese Cypress (Chamaecyparis obtusa), Sawara cypress (Chamaecyparis pisifera), Japanese Red Pine (Pinus densiflora), and Korean Pine (Pinus koraiensis) were 2.0, 1.6, 0.4, and 0.7 percent, respectively, and the maximum content of essential oils from all species were reached in July. By most of elicitors, the essential oil content was generally increased after 6 months later, but some of elicitors did not affect the content of essential oil. Finally, the appropriate inducers for artificially increasing the essential oil were respectively selected depending on each species; Schizophyllum commune Fries for Japanese Red Pine and Japanese Cypress, hydrogen peroxide for Korean Pine, and ${\beta}-pyridone$ for Sawara cypress. Especially, hydrogen peroxide and ${\beta}-pyridone$ could be wide spread inducer for all 4 species.
