Impact of Light-Emitting Diodes (LEDs) on Propagation of Orchids in Tissue Culture

摘要: LED technology is increasingly used in organ and tissue cultures of ornamental plants due to its ability adjust the spectral light composition physiological morphological requirements plants. This chapter presents an overview studies that have been conducted investigate effects light-emitting diodes (LEDs) on propagation different orchids under vitro condition. Most available reports are related use mixed red blue LEDs. In general, monochromatic enhances vegetative growth, whereas usually increases chlorophyll content regenerated plantlets. There some particular species which beneficial green ascertained induction protocorm-like bodies (PLBs). The application far-red combination with can be effective improvement quality micropropagated However, results vary depending tested light, species, or even cultivar as well applied environmental conditions. review also addresses future challenges adoption for improving growth development plantlets cultivated ex
