Optimizing in vitro growth of basil using LED lights

Tissue culture is an important technique for assessing the influence of light on plant growth. This study evaluated the in vitro cultivation of Ocimum basilicum cultivars under different light sources. First, an experiment was conducted to evaluate the effect of fluorescent and LED (Light Emitting Diode) light sources (yellow, blue, green, and red) on five basil cultivars (Cinnamon, Grecco a Palla, Italian Large, Limoncino, and Maria Bonita), followed by, another experiment, with two LED lights (Growlux and Blue). In vitro basil plants did not exhibit good growth under yellow lamps. The size of the roots of Cinnamon, Grecco a Palla and Limoncino cultivars under the two light conditions were similar. Moreover, the luminous condition of the Growlux lamps generated a greater quantity of leaves and fresh, and dry weight than blue LED lamps for Cinnamon, Grecco a Palla and Limoncino cultivars. Thus, it was concluded that the Growlux lamps promoted a greater amount of basil biomass.
