dc.description.abstract Light is crucial for plant growth and development. Changes in light signalling are responsible for much of the development patterns of shoots and roots. Kalanchoe blossfeldiana, a popular ornamental crop, has long been grown in controlled environments (greenhouses), with propagation largely achieved via rooted cuttings. Advances in light emitting diode (LED) lighting systems in the past decade allow for highly efficient and customizable light spectra that could be used to improve adventitious rooting in Kalanchoe. Although Kalanchoe is a popular crop, few studies examine effects of light quality on adventitious root and shoot promotion. Enhanced root development was observed in spectra containing greater amounts of blue light, while UV-A and Far-red light did not detect any appreciable improvements. Desirable shoot development was seen under lower blue levels than for root development, suggesting that a dynamic spectral environment throughout plant development may yield a better balance of root and shoot development. en_US
