MIELE, ALBERTO  e  RIZZON, LUIZ ANTENOR. ROOTSTOCK-SCION INTERACTION: 1. EFFECT ON THE YIELD COMPONENTS OF CABERNET SAUVIGNON GRAPEVINE. Rev. Bras. Frutic. [online]. 2017, vol.39, n.1, e-820.  Epub 20-Abr-2017. ISSN 0100-2945.  http://dx.doi.org/10.1590/0100-29452017820.

The interaction between rootstock, scion and environment can induce different responses to the grapevine physiology. Thus, the aim of this study was to determine the rootstock effect on the yield components of Cabernet Sauvignon (CS) grapevine grown in the Serra Gaúcha viticultural region. The experimental design was completely randomized blocks, with 15 treatments, three replicates and ten vines per plot. The results show that all variables evaluated were significantly affected by the year and the rootstock. The CS/Solferino was among other combinations influenced by the year and had higher significant yield/ vine. Indeed, it was higher than that CS/Rupestris du Lot, CS/101-14 Mgt., CS/3309 C, CS/5BB K, CS/161- 49 C, CS/1103 P. and CS/Isabel. The number of clusters/bud, per burst bud and per vine and the weight of clusters were affected by the rootstock as well. Pruning weight/vine, yield/pruning weight, leaf area/vine, leaf area index and leaf area/fresh fruit weight are variables related to the physiology of grapevine which were also affected by the rootstock. In general, rootstocks had adapted well to the environment where the experiment was carried out, giving vigor and high yield to Cabernet Sauvignon grapevine, which means that they may be used by grape growers in this region. However, the choice of the right rootstock depends on various aspects, such as those related to the soil characteristics, climate conditions, grape varieties, and even clones, and production purposes.
