Abstract

Four cultivars of tulips were forced in artificial light using fluorescent lamps TLD types, which emitted white, blue, red, yellow and green light. Quantum irradiance was determined on 12.5 and 25 μmol·m-2·s-1. Daylength was 6 and 12-hour respectively. Significant influence on the quality of tulips was observed under high quantum irradiance and long day. Tulips forced under red light have the highest shoots, the greatest weight and flowers. The blue light improved stems and leaves rigidity.
