Our phytotron includes four artificial light rooms using metal halide lamp (MHL) as light source. MHL is a good light source for plant growth. However, it has some problems such as high energy consuming and short half-life. Light-Emitting Diode (LED) is a new style light source. Since LED offers some advantages such as low voltage, low heat, long life and provide the specific light wavelength, it was considered as a good light source for plant growth in phytotron. Therefore, we established a new LED light room in NTU phytotron last year. In this project we will test the efficiency of LED on crop growth and development. Furthermore, we will try to modify the equipment setting in LED room for providing optimal plant growth conditions.發光二極體人工氣候室Light-Emitting Diodephytotron
