The Growth and Enhancement of Functional Ingredients for Health Improvement of Perilla Leaves Using LED Light Source with QD Application


Quantum dot (QD) has been used in various fields of mechanics and medical display. However, there is no studies of the application into agricultural fields. QD is an excellent source of the light production which is necessary for the plant growth. We demonstrated whether the application of Quantum dot lamps (QDLs) improves in quantity and quality of the perilla leaf production. Four types of QDLs which emit different wavelengths of lights were installed in the perilla greenhouse in Milyang, Korea. Our results showed that QDLs significantly increased in the perilla leaf growth compared with the control LED lamps. In addition HPLC analysis showed that perilla leaves exposed by Q2R lamps significantly increased contents of biologically functional components, such as chlorophyll, total flavonoid and phenolic-acid compounds, and several phenolic compounds (caffeic acid, coumaric acid, felulic acid and vanilic acid). The antioxidative capacity of perilla leaves extract varies depending on the type of QDLs. This is the first study providing important information regarding the application of quantum dot technology into the agricultural field.
