Abstract

The use of Light Emitting Diode (LED) technology for horticultural lighting is becoming increasingly feasible from an economic point of view. Rapid development of the technology is continuously bringing cheaper and more efficient equipment to the market. The possible use of monochromatic LED light for assimilation support and growth regulation in ornamental pot plants was examined in a series of studies. Different wavelengths including polychromatic white light were employed either as sole light source or in combination with natural light in greenhouse conditions. Plant growth and development was strongly affected by the different treatments. White light and blue light were found to be the most efficient for plant growth. However, stem elongation was dramatically enhanced by blue light in certain circumstances.
