Vitis vinifera L. cultivars have to be grafted on American grape rootstocks due to phylloxera and nematode damages, which makes it obligatory to determine their graft compatibility in a vineyard. For this purpose, any of four formulae developed by Perraudine, Branas, Spiegel-Roy & Lavee and Onaran was inconclusive to reliably determine the compatibility of a scion/stock combination. Therefore, it is needed to compare these results with values of pruning weight, yield and quality analyses obtained from a long-term grape growing. In addition, they have to be supported by histological and biochemical analyses.
