Patterns of Copper Bioaccumulation and Translocation in Grapevine Grafts Depending on Rootstocks

The long-term use of copper (Cu) fungicides in viticulture Europe has led to Cu accumulation vineyard top soils. However, less is known about the grapevine grafts after callusing process/before planting nursery. This paper presents capacity 5BB and SO4 rootstocks accumulate Cu, as well patterns translocation grafts. After heat forcing (callusing), Sauvignon Blanc on were grown pots for six months a glasshouse exposed various formulations (Cu-oxychloride, Cu-gluconate) concentrations peat (50, 150, 500, 1000 mg dry weight (DW)). In addition monitoring shoot growth dynamics analyzing content graft organs, bioaccumulation (BAFs) factors (TFs) calculated. mean ranked follows: roots (15–164) > rootstock trunks (8–38) canes (5–21) kg−1 DW. depended formulation concentration substrate. Higher was found both (5BB SO4, 23–155 15–164 DW, respectively) lowest (less than 10 DW) Cu-oxychloride-treated peat. Based BAFs TFs, could be considered exclusive. A higher rate determined systemic Cu-gluconate rootstock. With length measurements, significant inhibitory effects not confirmed, despite that clearly expressed first two growth. Soils containing more 500 Cu/kg−1 are suitable growing vine
