The role of rootstocks for grape growing adaptation to climate change. Meta-analysis of the research conducted in Spanish viticulture

Rootstock election is one of the key decisions when designing a vineyard. Although research performed to determine effect they induce in behaviour scion varieties not scarce, it easy have global idea, as results are usually published scattered. In this work, we re-examine previous conducted Spain on rootstock implications vine agronomic performance through meta-analysis (MA). As result, were able integrate information reported 20 articles that included experimentation with 36 different and 47 rootstocks, totalling 764 individual records. However, was filtered before meta-analysis, number decreased 312 records, for which Response Ratios (RR) calculated. The characteristics conferred by more closely related itself, rather than Vitis sp. crossing used create rootstock. Several rootstocks identified suitable adapting future climate change conditions, far moderate sugar accumulation pH (161-49 C, 41-B MGt 420A MGt). Meanwhile, 140 Ru 5-BB observed provide high contents despite their yield. conclusion, being based data from single country, shown be useful tool enhancing value rootstocks. Combining both peer-reviewed technical journals helped assessment although further steps should taken facilitate integration (harmonisation measurement reporting procedures, open repositories, etc).
