Effect of light sources on the micropropagation of mexican origanum (Lippia graveolens)

Abstract

The use of different light sources in the micropropagation of plant species has been studied since the 1970s. At present, studies are being carried out not only to increase production, but to greatly reduce the energy demand of the lamps that are used for this purpose. In the present work, light sources with different wavelengths in fluorescent lamps and LED light were used to test the morphological and phytochemical response of Mexican origanum plants. A similar response was obtained regarding the production of axillary buds and leaves with the use of broad spectrum light and LED light. On the other hand, the main photosynthetic pigments (chlorophyll a and b and carotenoids) are also produced in a similar way when this plant is propagated under broad spectrum light and LED light.
