Abstract:
Lemnaceae, commonly called "duckweeds", are known to be especially rich in crude protein and amino acids, and in secondary metabolites such as carotenoids; they generally have a low content of fats and a high amount of fibre. These characteristics make them totally suitable as an animal and human food source, indeed they have been traditionally consumed as human food and as animal feed in many Asian countries for generations, and the interest towards them as a functional food is nowadays increasing also in Western countries. The recent technology of light-emitting diodes proved to have a high potential in increasing yield and triggering the biosynthesis of nutritious compounds of many crops, being light involved in main biological processes such as photosynthesis, phototropism and photomorphogenesis of plant germination and growth. LED technology is highly versatile, is safe and durable, and allows to actively control the different light parameters affecting plants’ processes, namely light quality, light intensity and duration, in order to influence different metabolic pathways. Therefore, in the present research the possibility of influencing the quality parameters of duckweeds by propagating them under different LED lamps (white LEDs, red LEDs andblue LEDs) was investigated. In particular, the effect of diverse light quality on duckweeds' biosynthesis of carotenoids, chlorophylls and proteins was studied, in order to determine if there are concrete possibilities of improving the plants quality by treating them with LED lamps during growth.
