Investigation on morphology and physiology of potted rose grown with light from microwave-plasma and high-pressure sodium lamps

摘要

In this study, microwave-plasma lamps (MPL) that emit sun-like light were tested. Plant cultivation experiments using potted roses were conducted with supplemented assimilation light in greenhouse and climate chamber to investigate the influence of artificial sunlight on external and internal plant quality. Light from high-pressure sodium lamps (HPS) was used as a reference. Plant growth parameters were recorded, and the chlorophyll and flavonoid contents in rose leaves were determined. Furthermore, the photosynthetic rate and soluble sugar content were measured in the climate chamber.
