Abstract

Three cultivars of pot chrysanthemums (’Springfield’, ’Kodiak’ and ’Baton Rouge’) were supplementary illuminated with sodium lamps during November and December – 2 hours before sunset and 2 hours after sunset. Quantum irradiance was 60 mol m^-2 s^-1. Illuminated plants flowered 36–52 days earlier. Quality of plants was improved.
