Comparison of accumulation of stilbene compounds and stilbene related gene expression in two grape berries irradiated with different light sources

In this study, the accumulation of stilbene compounds and the expression of genes related to their syntheses in ‘Campbell Early’ and ‘Kyoho’ grapes (Vitis sp.) were investigated by irradiating the harvested berries with four different light sources (white fluorescent and purple, blue, and red LED lights) for 48 hours. The total concentrations of five stilbene derivatives at 24 hours after irradiation differed in response to different light...
