Summary
This paper by Davey et al., published in the Journal of the Science of Food and Agriculture in 2000, investigates the biochemistry of ascorbate (vitamin C) accumulation in apple fruit, with particular attention to the enzymatic mechanisms governing its synthesis and regeneration. The work contributes to understanding why ascorbate levels vary in fruit and what metabolic controls are operative. It is likely to be a foundational analytical study drawing on controlled laboratory characterisation of apple tissue rather than a field-based agronomic trial.
UK applicability
Apples are widely grown in the UK, particularly in Kent and other southern counties, and understanding the biochemical determinants of vitamin C content is relevant to UK horticulture breeding and quality assessment programmes. The findings may inform efforts to select or develop cultivars with enhanced nutritional quality.
Key measures
Ascorbate concentration (mg/100g fresh weight); enzyme activity (nmol or µmol per mg protein per minute) for ascorbate biosynthesis and recycling enzymes
Outcomes reported
The study examined ascorbate (vitamin C) concentrations and the activity of enzymes involved in ascorbate biosynthesis and recycling in apple fruit tissue. It likely reported variation in ascorbate levels across developmental stages or cultivars and characterised relevant enzymatic pathways.
