Light source such as fluorescent lamps, metal halide lamps and high-pressure sodium lamps are generally used for in vitro cultures. However, these lights contains unnecessary wavelength that are low in quality for stimulating growth [8] [9]. Furthermore, the use of these lights consumed a lot of electricity and it was reported that tissue cultured lab consumed 65% of total electricity [10]. Light Emitting Diode also known as LED light has been utilized globally in agriculture as an alternative light source for plant growth and photosynthesis. LEDs have attracted considerable interest because of their wavelength specificity and narrow bandwidth, small mass and volume, long-life and minimum heating [11][12].
Morphology and physiology of in vitro grown plants are regulated by various micro-environmental
factors such as light, temperature, humidity and carbon dioxide [12][13]. Inadequate or insufficient light may cause harmful for plant growth or led to
