Supplementary lighting is commonly used to increase yield and quality of ornamental plants. Light – emitting diodes (LEDs) represent a promising technology for the greenhouse industry that has technical advantages over traditional sodium lamps. In the production of chrysanthemums it is particularly important to have properly developed and well-rooted cuttings. In year – round controlled cultivation of chrysanthemums it is necessary to use supplementary lighting from November to mid-February. The possibility of application of LED during the rooting of two cultivars of chrysanthemums was investigated. Our data suggest that LEDs are suitable replacements for HPS lamps as supplemental light sources during the cuttings rooting. Lower energy consumption compared to conventional sodium lamps will increase the profitability of year – round controlled production of chrysanthemums.
