Energiezuinige belichting bij chrysant

Research output: Book/ReportReportProfessional


The effect of three different lighting systems was investigated on chrysanthemum, i.e. HPS, hybrid lighting (50% HPS and 50% LED), and LED lighting. The study looked at the effect of exposure on rooting, on the morphology in the long-day period, and for a whole crop in spring and autumn. Then also looked at post-harvest quality and shelf life. The spring crop showed that production was highest under hybrid lighting with end-of-day far red. A test with young chrysanthemum cuttings (cv. Baltica) revealed that end-of-day far red did not have a positive influence on light interception or leaf area. Spectral composition also affected rooting: only blue or red light led to fewer roots than spectra where far red was added. In an autumn crop 14 varieties were grown under HPS, hybrid and LED lighting. Production, quality and light use efficiency was highest under HPS, but the energy consumption in this treatment was the highest as well. Cultivating under LEDs cost 20% less electricity (for lighting), but the production and quality were less than under HPS lighting
