英文摘要	Almond (Prunus dulcis Mill. (D.A. Webb)) plantations in irrigated semi-arid areas need to successfully face the new scenarios of climate change combining sustainable irrigation strategies and tolerant cultivars to water stress. This work examines the response of young almond (cvs. Guara, Marta, and Lauranne) subjected to different irrigation doses under semi-arid conditions (South-West Spain). The trial was conducted during two seasons (2018-2019) with three irrigation strategies: A full-irrigated treatment (FI), which received 100% of the irrigation requirements (IR), and two sustained-deficit irrigation strategies that received 75% (SDI75) and 65% (SDI65) of IR. Crop water status was assessed by leaf water potential (psi(leaf)) and stomatal conductance (g(s)) measurements, determining the yield response at the end of each season. Different physiological responses for the studied cultivars were observed, especially considering the psi(leaf) measurements. In this way, cv. Marta behaved more tolerant, while cvs. Guara and Lauranne maintained higher g(s) rates in response to water stress. These differences were also observed in terms of yield. The cv. Lauranne did not reflect yield losses, and the opposite trend was observed for cv. Guara, in which reductions on fruit numbers per tree were detected. On overall, effective irrigation water savings (approximate to 2100 m(3).ha(-1) in SDI65) could be feasible, although these responses are going to be substantially different, depending on the used cultivar.
