Abstract

The effect of blue and red light mixture and white-light (RGB) from monochromatic light-emitting diodes on growth and morphogenesis of sugarcane (Saccharum officinarum) plantlets in vitro, was investigated. Light treatments with blue/red light intensity percentage ratio 70/30, 50/50, 40/60, 30/70, and also white-LED light were applied during a period of 20 days with a photoperiod of 16 h per day. Results indicate that the blue/red light blend ratio of the illumination system plays a major role in fresh weight, length, and shoot multiplication of plantlets cultured in vitro. White-light via blended primary colors monochromatic LEDs illumination of the plantlets culture was also evaluated and compared with blue/red lighting
