USING SUNLIGHT/ LEDS FOR PLANT TISSUE CULTURE TECHNIQUE TO REDUCING ELECTRICITY CONSUMPTION AND IMPROVING ENVIRONMENTS

Abstract

Plant tissue culture technique has been widely used for propagation of various important crops and production of somaclonal and gametoclonal variants. It could reduce materials, time cost and space for plant propagation as well as provide a vast potential to produce plants with high quality and disease-free. The main challenge of plant tissue culture technique over conventional propagated methods is high energy consumption. Since, the light quantity and quality are not only important for photosynthesis, but also for photoperiodism and photomor phogenensis which directly affects the efficiency of plants' propagated system. The aim of this work is to implement an optical day lighting system combined with LEDs for in vivo propagation to reduce electrical energy and create a high preformat light quality, which conducts a potential strategy to save input energy and increase quality of in vitro propagated plants. Our preliminary results for utilizing in vivo propagation of Phalaenopsis amabilis showed the potential of this system for saving input energy during plant tissue culture procedures and providing a quality light environment. This is one of the important factors that positively affect the ecosystem and environment.
