1. A method of increasing an amount of one or more compounds selected from the group consisting of stilbenoids, TCA cycle metabolites, polyamine alkaloids, 4-aminobutyric acid, abscisic acid and salts in a plant cell culture, the method comprising steps of:
irradiating the plant cell culture with light at a wavelength range of 275-295 nm, at a fluence of 50,000-2,500,000 μmol/m2, while at the same time a fluence at a wavelength range of 200-270 nm is less than 20% of the fluence at the wavelength range of 275-295 nm; and then
storing the irradiated plant cell culture for 1 day or more in a dark place,
wherein the plant cell culture is a callus cell culture.
