Abstract
When living walls are installed indoors, the application of artificial lighting is essential to ensure satisfactory growth and flowering of plants.
In this study, the effect of different LED lamp color temperatures on the growth and flowering of Anthurium andraeanum Linden ex André (flamingo flower) in indoor living walls was evaluated.
The study was conducted in an enclosed space at the Laboratory of Floriculture and Landscape Architecture at the Agricultural University of Athens and lasted for 7 months.
The three types of LED lamps evaluated in the study were: a) warm lighting 2700 K; b) neutral lighting 4000 K; and c) cool lighting 6500 K. The effect of different LED lamp color temperatures on the plants was assessed by determining the plant coverage, leaf color, and number of flowers.
A gradual increase in plant coverage was observed in all three types of lighting, with neutral and cool lighting exhibiting higher values compared to warm lighting.
The green color of the plant leaves remained relatively stable throughout the study for all three types of lighting.
In contrast, the number of flowers on all plants decreased during the study.
On the last sampling date, an average number of flowers was recorded, equal to two flowers for cool and warm lighting and three flowers for neutral lighting.
It is worth noting that the initial average number of flowers for all three types of lighting was similar and equal to 12 flowers.
