Figure 9From: Thiamine modulates metabolism of the phenylpropanoid pathway leading to enhanced resistance to Plasmopara viticolain grapevineIncrease of the antioxidant potential of grapevine plants after thiamine treatment. (A) COADS determination of the total anti-oxidant potential of leaf extracts from water (white bars) and thiamine-treated (solid bars) grapevine plants. (B) Individual contribution of phenolic compounds to the anti-oxidant potential of water (white bars) and thiamine-treated (solid bars) plants. Data are the mean of 3 independents experiments.Back to article page
