METHOD FOR ENHANCING THE NUTRITIONAL VALUE IN AN EDIBLE PLANT PART BY LIGHT, AND LIGHTING DEVICE THEREFORE

摘要

The invention provides a method for enhancing the nutritional value in a first plant part (2) of a crop (1), wherein the first plant part (2) comprises an edible plant part, wherein the crop (1) in addition to the first plant part (2) comprises one or more other plant parts (3), wherein the method comprises illuminating during a nutritional enhancement lighting period a target part (5) of said first plant part (2) with horticulture light (511) that is selected to enhance formation of a nutrient in said first plant part (2) while allowing one or more other plant parts (3) to be subjected to different light conditions, wherein the nutritional enhancement lighting period is started within two weeks from harvest of the first plant part (2).

主权项

1. A method for enhancing the nutritional value in a first plant part of a crop, wherein the first plant part comprises an edible plant part, wherein the crop in addition to the first plant part comprises one or more other plant parts, wherein the method comprises preferentially illuminating during a nutritional enhancement lighting period a target part of said first plant part with horticulture light that is selected to enhance formation of a nutrient in said first plant part while allowing one or more other plant parts to be subjected to different light conditions, wherein the nutritional enhancement lighting period is started within a period of two weeks before harvest of the first plant part, wherein the first plant part receives during the nutritional enhancement lighting period light with a different spectral wavelength distribution and/or intensity than the one or more other plant parts.
