A method of treating a plant by irradiating the plant with light in a wavelength range of 300 nm to 325 nm at a fluence of 4,000 μmol/mto 50,000 μmol/m, while a fluence of light in a wavelength range of 290 nm or less irradiated to the plant is less than 20% of that of the light in the wavelength range of 300 nm to 325 nm. Alternatively, the plant is not irradiated with light at any wavelength of 290 nm or less; and then the plant is infected with a microorganism.

Method of treating plant, method of producing plant infected with microorganism, method of producing fermented plant product, and plant treatment apparatus

The present disclosure relates to a method of increasing an amount of a stilbenoid, and/or one or more compounds selected from the group consisting of TCA cycle metabolites, polyamine alkaloids, 4-aminobutyric acid, abscisic acid and salts thereof in a plant, the method comprising steps of:

Method of treating plant and method of making plant-based food or drink product

A plant treatment apparatus includes: a plant holding unit; an ultraviolet irradiation unit configured to irradiate a plant held by the plant holding unit with light comprising ultraviolet light in a wavelength range of no less than 270 nm and no more than 290 nm; and either (i) a plant immersion unit configured to immerse the plant held by the plant holding unit into a liquid that comprises water and is held by the plant immersion unit, or (ii) a liquid ejection unit that ejects the liquid towards the plant held by the plant holding unit.

Plant conveyance and irradiation apparatus

A method of cultivating algal cells of an algae belonging to a class selected from Chlorophyceae, Euglenophyceae, Bacillariophyceae and Haptophyceae includes: irradiating the algal cells with an artificial light having a ratio of (i) photon flux density in a wavelength range of 520-630 nm to (ii) photosynthetic photon flux density, that is 65% or more; and measuring a cell size of the algal cells. Irradiation and non-irradiation of the algal cells with the artificial light are switched, or the photon flux density in the wavelength range of 520-630 nm is changed, according to the measured cell size.

Method of cultivating algae and photobioreactor

Provided is a method of treating a post-harvest plant after harvest, the method including: irradiating a harvested plant with light having a peak wavelength in a wavelength range from 270 to 290 nm and/or light having a peak wavelength in a wavelength range from 370 to 400 nm at an irradiance effective to increase an amount of at least one rare cannabinoid compound and/or at least one terpene compound in the harvested plant, wherein an irradiance of light of all wavelengths in a wavelength range from 410 to 700 nm received by the harvested plant during the irradiation is less than 20% of the irradiance of the light having a peak wavelength in the wavelength range from 270 to 290 nm and/or less than 20% of the irradiance of the light having a peak wavelength in the wavelength range from 370 to 400 nm.

Method and apparatus for treating post-harvest plant

A method of treating a non-human animal subject includes irradiating, one or more times, light having a peak wavelength in a range of 315-335 nm to an affected area of the animal subject.

Animal treatment apparatus, phototherapeutic apparatus, and animal treatment method

A method for treating spermatozoa of an animal includes: irradiating the spermatozoa with light having wavelengths in a range of 390-420 nm at a fluence effective to increase motility of the spermatozoa by 75% or more.

Method and apparatus for increasing sperm motility

An object of the present invention is to provide a method that can effectively/efficiently increase the amount of a phenolic compound such as a polyphenol. The invention provides a method for increasing an amount of a phenolic compound in a plant, or a method for producing a plant containing an increased amount of a phenolic compound, the method comprising irradiating the/a plant with ultraviolet light, wherein a fluence at wavelengths of 270 to 290 nm is 1500 to 50000 &#x3bc;mol/mand a fluence at wavelengths of 310 to 400 nm is less than 50% of that at wavelengths of 270 to 290 nm.

Method for increasing amount of phenolic compound in plant

A method of cultivating algal cells of an algae belonging to a class selected from Chlorophyceae, Euglenophyceae, Bacillariophyceae and Haptophyceae includes: irradiating the algal cells with an artificial light having a ratio of (i) photon flux density in a wavelength range of 520-630 nm to (ii) photosynthetic photon flux density, that is 65% or more; and measuring a condition of the algal cells and/or a condition of an algal cell culture provided by cultivating the algal cells. Irradiation and non-irradiation of the algal cells with the artificial light are switched, or the photon flux density in the wavelength range of 520-630 nm is changed, according to the measured condition of the algal cells and/or the measured condition of the algal cell culture.
