Abstract
[Problem] To provide a method for suppressing greening of potatoes after harvest. [Solution] A method that comprises: a first step for simultaneously irradiating far-red light and light in a wavelength range other than the far-red light range to post-harvest potatoes; and a second step which involves one time period wherein the far-red light alone is irradiated to the potatoes and another time period wherein neither the far-red light nor the light in a wavelength range other than the far-red light range is irradiated thereto.
Claims10
A method for suppressing greening of a potato tuber previously exposed to white light, comprising:
- in a first time period, irradiating the potato tuber with far-red light and light of a wavelength region other than the far-red light, simultaneously;
- in a second time period that is directly subsequent to the first time period, irradiating the potato tuber with the far-red light and not irradiating the potato tuber with the light of a wavelength region other than the far-red light;
- in a third time period that is directly subsequent to the second time period, not irradiating the potato tuber with the far-red light and not irradiating the potato tuber with the light of a wavelength region other than the far-red light;
- and
- in a fourth time period that is directly subsequent to the third time period, irradiating the potato tuber with the far-red light and not irradiating the potato tuber with the light of a wavelength region other than the far-red light;
- wherein the first time period, the second time period, the third time period, and the fourth time period occur within a 24 hour period.
