The Influence Of Spectral Quality On Primary And Secondary Metabolism Of Hydroponically Grown Basil, Hunter Albright Hammock Aug 2023

The Influence Of Spectral Quality On Primary And Secondary Metabolism Of Hydroponically Grown Basil, Hunter Albright Hammock

Doctoral Dissertations

This dissertation explores the influence of spectral quality from supplemental lighting and seasonal changes on primary and secondary metabolism in hydroponically grown greenhouse basil. It aims to enhance understanding of plant/light interactions and provide practical insights for light emitting diode (LED) manufacturers and commercial growers. The research is premised on the hypothesis that altering spectral quality can significantly impact primary and secondary metabolism, potentially improving flavor and increasing phytonutrients with health benefits. This project involved four phases, each building on the results of the previous ones. In Phase 1, different basil varieties were evaluated to determine aroma volatile profiles and …
