Publication Open Access The role of rootstocks for grape growing adaptation to climate change: meta-analysis of the research conducted in Spanish viticulture(International Viticulture and Enology Society, 2023) Santesteban García, Gonzaga; Rekarte, Isabel; Torres Molina, Nazareth; Galar Martínez, Mónica; Villa Llop, Ana; Visconti, Fernando; Intrigliolo, Diego S.; Escalona, José M.; Herralde, Felicidad de; Miranda Jiménez, Carlos; Agronomía, Biotecnología y Alimentación; Agronomia, Bioteknologia eta Elikadura; Institute for Multidisciplinary Research in Applied Biology - IMABRootstock election is one of the key decisions when designing a vineyard. Although the research performed to determine the effect they induce in the behaviour of scion varieties is not scarce, it is not easy to have a global idea, as results are usually published scattered. In this work, we re-examine previous research conducted in Spain on rootstock implications on vine agronomic performance through the performance of a meta-analysis (MA). As a result, we were able to integrate the information reported in 20 articles that included rootstock experimentation conducted with 36 different varieties and 47 different rootstocks, totalling 764 individual records. However, when the information was filtered before the meta-analysis, this number decreased to 312 records, for which rootstock Response Ratios (RR) were calculated. The characteristics conferred by the rootstock were more closely related to the rootstock itself, rather than to the characteristics of the Vitis sp. crossing used to create the rootstock. Several rootstocks were identified as more suitable for adapting to future climate change conditions, as far as they were able to moderate sugar accumulation and pH (161-49 C, 41-B MGt and 420A MGt). Meanwhile, 140 Ru and 5-BB were observed to provide high pH and sugar contents despite their high yield. In conclusion, despite being based on data from a single country, the meta-analysis was shown to be a useful tool for enhancing the value of previous research on rootstocks. Combining articles from both peer-reviewed and technical journals helped in the assessment of the implications of different rootstocks, although further steps should be taken to facilitate data integration (harmonisation of measurement and reporting procedures, open data repositories, etc).Publication Open Access Challenges of viticulture adaptation to global change: tackling the issue from the roots(Wiley, 2021) Marín Ederra, Diana; Armengol, J.; Carbonell-Bejerano, P.; Escalona, José M.; Gramaje, David; Hernández-Montes, E.; Intrigliolo, Diego S.; Martinez-Zapater, J. M.; Medrano, H.; Mirás-Ávalos, José M.; Palomares Rius, Juan Emilio; Romero Azorín, Pascual; Savé, R.; Santesteban García, Gonzaga; Herralde, Felicidad de; Agronomía, Biotecnología y Alimentación; Agronomia, Bioteknologia eta Elikadura; Universidad Pública de Navarra / Nafarroako Unibertsitate PublikoaViticulture is facing emerging challenges not only because of the effect of climate change on yield and composition of grapes, but also of a social demand for environmental-friendly agricultural management. Adaptation to these challenges is essential to guarantee the sustainability of viticulture. The aim of this review is to present adaptation possibilities from the soil-hidden, and often disregarded, part of the grapevine, the roots. The complexity of soil-root interactions makes necessary a comprehensive approach taking into account physiology, pathology and genetics, in order to outline strategies to improve viticulture adaptation to current and future threats. Rootstocks are the link between soil and scion in grafted crops, and they have played an essential role in viticulture since the introduction of phylloxera into Europe at the end of the 19th century. This review outlines current and future challenges that are threatening the sustainability of the wine sector and the relevant role that rootstocks can play to face these threats. We describe how rootstocks along with soil management can be exploited as an essential tool to deal with the effects of climate change and of emerging soil-borne pests and pathogens. Moreover, we discuss the possibilities and limitations of diverse genetic strategies for rootstock breeding.
