Regulation of tomato fruit ascorbate content is more highly dependent on fruit irradiance than leaf irradiance

摘要

Background and AimsThe mechanisms involving light control of vitamin C content in fruits are not yet fully understood. The present study aimed to evaluate the impact of fruit and leaf shading on ascorbate (AsA) accumulation in tomato fruit and to determine how fruit sugar content (as an AsA precursor) affected AsA content.
