METHOD FOR INCREASING CALCIUM OF JAPANESE MUSTARD SPINACH USING LIGHT

摘要

PROBLEM TO BE SOLVED: To provide a simple method, capable of increasing the calcium content more than that of the conventional Japanese mustard spinach (Brassica rapa var. perviridis) in cultivating Japanese mustard spinach in a plant cultivation facility where a plant is cultivated in a cultivation space divided from the outside using artificial light source such as a plant factory.;SOLUTION: A method includes the following process. In cultivating Japanese mustard spinach (Brassica rapa var. perviridis) in the plant cultivation facility where a plant is cultivated in a cultivation space divided from the outside using the artificial light source, a monochrome light emitting diode having a light emission peak in the visible light region is used as the artificial light source to thereby increase the calcium content of the Japanese mustard spinach.;COPYRIGHT: (C)2014,JPO&INPIT
