ResumoThe effects of CO2 enrichment and supplementary lighting on the production and flower stem quality of five Alstroemeria cultivars (`Barbara', `Fiona', `Helios', `Mona Lisa' and `Tiara') were studied. CO2 enrichment up to 900 μl l−1 alone was beneficial for an increase in the number of flower stems and flower stem quality regardless of the use of supplementary lighting. Supplementary lighting alone enhanced flower stem production and quality to a lower extent than CO2 enrichment. The combination of both supplementary lighting and CO2 enrichment resulted in superior flower stem production for Alstroemeria `Fiona', `Helios' and `Mona Lisa', and flower stem quality for Alstroemeria `Barbara', `Fiona' and `Mona Lisa'.
