Tocopherols, Phylloquinone, Ascorbic Acid, and Sugar Contents in Hydroponically Grown Lettuce

Growing vegetables in controlled environments (CEs), such as hydroponics, aquaponics, and vertical structures, is a rapidly expanding industry Florida the United States, especially nearby urban areas. Although lettuce ( Lactuca sativa ) still mostly produced fields, growing CEs proximal to areas has become increasingly popular because it may facilitate reduced transportation time associated postharvest degradation. Lettuce among top-most consumed States could provide some of nutrition missing US diet. This research was planned understand levels vitamins that are key for human health, including vitamin E (tocopherols), K 1 (phylloquinone), C (ascorbic acid), grown greenhouse hydroponics. germplasm using hydroponic nutrient film technique system three experiments: at beginning, middle, end Florida, USA, season (from Aug 2020 Mar 2021). Genetic variation these were found tested four morphological types lettuce, romaine, Boston, Latin, leaf. In addition, sugar analysis conducted this germplasm, which fructose most abundant sugar. A significant genotype × environment (G E) interaction observed, indicating compounds, vitamins, dependent. However, presence certain non-crossover G interactions indicates selecting representative result new cultivars with higher content. marks initial steps improve can contribute better health consumers, not highest amount compounds but offset due its high consumption.
