Artificial light quality affects herbivore preference for seedlings
OSAKA, JAPAN—In horticultural production, growers often depend on systems that use artificial light to produce high-quality transplants. Although the systems are efficient, fluorescent lamps can produce plants with shorter shoots than those grown under natural light. Studies have indicated that this reduced shoot elongation is due to the high red:far red ratio of typical commercial fluorescent lamps, which emit little far red irradiation.
In natural environments a reduction in the red:far red (R:FR) ratio resulting from the absorption of red light by neighboring vegetation ...
