Abstract:
Light is an important environmental factor which influences on plant growth and development. Plant utilizes the light energy for photosynthesis and as well as light signalling in different assimilation process. In intensive horticulture production system, natural light levels often limit the crop production during certain periods. Artificial lighting is used on numerous flowering species to increase photosynthesis, create an inductive photoperiod, or both. To improve plant production and product quality, light intensity, spectrum and photoperiodic adaptation is the need of the hour. Change in light intensity, duration and quality causes change at plant physiological and biochemical level thus it influences their morphology and functioning. Among the use of varied artificial light sources in horticultural sector, use of Light Emitting Diodes (LEDs) in floriculture ensures the increased light (energy) use efficiency in greenhouse production. It is understand that, LED technology allows the application of monochromatic wavelengths or their combinations to improve plant growth.
