The aim of the experiment was to compare the effect of LED and fluorescent lamps as sources of light on growth and development of sweet basil (Ocimum basilicum L.) and lemon balm (Melissa officinalis L.). The experiment was conducted in growth chambers under controlled conditions. Plant response to the applied light sources was found to be varied. Basil plants produced greater fresh herbage mass as well as shoot height under Fl lamps. The employed sources of light did not have a significant effect on leaf area or photosynthesis rate in these plants. Light sources did not influence the growth rate of lemon balm plants, but these plants were characterised by a greater net photosynthesis value when grown under FL tubes as compared to LEDs. It can be concluded that the response of plants to the applied light is individual and depends on the species.
