I am pursuing a doctoral degree in Horticulture under Dr. Erik Runkle's guidance. My research focuses on optimizing the radiation spectrum of sole-source light-emitting diodes (LEDs) for plant growth and quality during young ornamental plant production. There's been a fundamental shift of incorporating LEDs into commercial controlled-environment agriculture due to their high energy efficiency, longevity, and waveband specificity. Using a mixture of red and blue radiation for sole-source LED lighting has been widely considered desirable from plant growth and energy efficiency perspective. However, this limited radiation combination is not necessarily optimized for many plant growth applications as well as is difficult for people to see plants to evaluate growth. During my Ph.D. research, I will investigate the impacts of using additional narrow- or broad-band lighting, including far-red and white, to improve growth and quality attributes of young ornamental plants. Also, the underlying mechanisms of the spectral quality manipulations will be identified based on thorough photosynthesis and plant morphology study.
