  • MANIPULATION OF LIGHT SPECTRAL QUALITY TO REDUCE PARASITISM BY CUSCUTA AND OTHER PLANT PARASITES
    Publication number: 20160021830
    Abstract: The invention employs the use of light spectral manipulation as a defense method against parasitic plants in the genus Cuscuta. According to the invention, the manipulation of light spectra is employed to present a ratio of red light (650-670 nm) to far red light (710-740 nm) that is higher than natural sunlight. The manipulation can be passive, such as the use of photoselective film, or active, such as use of a lighting control mechanism within a plant cultivation house growth for delivering appropriate irradiation spectra to crops, such as the use of light-emitting diodes.
