4. UNGRAFTED ROOTLINGS
In the last thirty years, the practice of grafting onto ungrafted rootling rootstocks of Vitis vinifera in the field has been gradually abandoned (starting in the north and going southwards). Today this practice is almost exclusively used for table grape varieties, whose market can be assimilated to the fruiting species that are strongly influenced by trends. Grafting in the field defers the decision on the choice of variety by a year. Table 1.12 The evolution of nursery production of ungrafted rootlings illustrates this phenomenon, whereas, table 1.13 Certified ungrafted cuttings for rootstocks, shows how production is concentrated on rootstocks 140 RU (good quality for table grapes) and 1103 P, mainly used in the regions of Apulia and Sicily.
