Production of value-added transplants in closed systems with artificial lighting

摘要

The use of artificial light in commercial plant production is most economically favorable when plants are small, so a large number of plants can be simultaneously irradiated by a minimum of lighting units. Growing closely spaced plants from seeds or cuttings to transplants for field or greenhouse use is a major application of this approach. Transplants increase their economic value when their vegetative or reproductive responses are appropriately regulated by environmental manipulation. Closed transplant production systems with efficient artificial lighting are more cost-effective than using natural lighting alone. These systems can minimize energy and material consumption while, at the same time, optimize photosynthetic and photomorphogenic characteristics. In the future, more transplants will be produced under artificial light in closed systems. This paper reviews the impact of artificial lighting on plant growth and the production of quality transplants in closed systems with artificial lighting.
