The effect of supplementary assimilation lighting on macro and micronutritional status of pot chrysanthemums grown in the period of insolation deficit was examined. Three cultivars of pot chrysanthemums were used: ‘Baton Rouge’, ‘Kodiak’ and ‘Springfield’. During November and December, for four hours a day, only half of the plants were illuminated with supplementary sodium lamp. Light intensity was 5000 lx. The supplementary assimilation lighting significantly modified macro and micronutritional status of chrysanthemums. The influence of supplementary lighting on the nutrients content in the leaves was greater in case of the macroelements than microelements.
