Publication Open Access Evaluation of the incidence of severe trimming on grapevine (Vitis vinifera L.) water consumption(Elsevier, 2019-03-01) Abad Zamora, Francisco Javier; Marín Ederra, Diana; Loidi Erviti, Maite; Miranda Jiménez, Carlos; Royo Díaz, José Bernardo; Urrestarazu Vidart, Jorge; Santesteban García, Gonzaga; Agronomía, Biotecnología y Alimentación; Agronomia, Bioteknologia eta Elikadura; Institute for Multidisciplinary Research in Applied Biology - IMAB; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, FPI-UPNA-2016; Gobierno de Navarra / Nafarroako GobernuaViticulture in Southern Europe heads towards a scenario of drier and warmer the growing seasons due to climate change. This decrease in the amount of water available for the vines and increase in evapotranspiration make necessary finding strategies to reduce vineyard water needs. In this context, the effect of severe trimming (40¿60% of shoot length), performed at pea-size stage, on plant water status was evaluated in four different vineyards located in North of Spain. Severe trimming improved plant water status clearly only when climate conditions were more demanding, whereas only a slight improvement or no change was observed elsewhere. Lower leaf areas resulted in less water deficit following a logarithmical trend revealing that the effect was more pronounced at low leaf area levels. Severe trimming had non-significant effects on cluster number, yield and cluster weight, but presents a tendency to reduce total soluble solids content and to increase total acidity, consequently delaying ripening.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.
