The aim of this study was to evaluate the effect of LED (light-emitting diodes) lighting on lily development and flowering time. In controlled environments the trial was carried out in February–March, 2015. Two cultivars from different groups: Asiatic lily cultivar ‘London Heart’ and LO (Lilium longiflorum × Oriental hybrid) lily cultivar ‘Triumphator’ were forced at different environments – natural lighting and LED lighting (LED). Four bulbs per cultivar and treatment were planted each in 15 cm diameter pots. The LED light was provided for 8 hours a day (08:00–12:00 and 15:00–19:00) to create a long-day photoperiod is greater than 14 hours. The effectiveness of LED was evaluated by recording the data of growth and flowering stages – the bud formation and beginning of flowering. The treatment with LED resulted in a significantly faster development of lily growth, promoting flowering and shorter forcing time (p is less than 0.05 vs. natural lighting). Mean flowering time under LED of the cultivar ‘London Heart’ was 58 days after planting and for the cultivar ‘Triumphator’ 61 days compared with natural lighting – 63 and 67 days, respectively. Our results suggest that LED lighting can be successfully used to provide long-day photoperiod to promote flowering of lily cultivars tested in this study. Further studies are required to clarify the light spectrum influence on lily flowering.
