| Abstract:
Japanese mint (Mentha arvensis L.) plants were grown under three different treatments of light quality (blue, green and red light) provided by colored fluorescent lamps. Leaf dry weight of the plants was 1.3 and 1.2 times higher in the red-light treatment than in blue- and green-light treatments, respectively. The content of l-menthol (mg/plant), which is the main component of the essential oil in the plants, was 1.4 times higher in the red-light treatment than in the blue- and green-light treatments, while the l-menthol concentration (mg g-1 leaf DW) was not significantly different among the treatments. Our results suggest that red light is beneficial for producing Japanese mint plants with high essential oil contents under controlled environments with artificial light. | |
