Changes in ascorbic acid contents in various market forms of spinach (Spinacia oleracea L.) during postharvest storage in light (20-25 μmole m^<->2 s^<-1>) and dark conditions were investigated. In the leaves of whole spinach plants, the decline in ascorbic acid contents, specifically in mature leaves which comprise the bulk of the plants, was effectively minimized with the provision of supplemental lighting. Supplemental lighting has likewise been demonstrated to positively affect the ascorbic acid status of leaves from spinach plants with trimmed off parts and those without roots, and in detached spinach leaves. Light then seems to be an effective environmental factor in ascorbic acid maintenance of spinach leaves during the postharvest period.
