Productive response of Macabeo varietie in two locations of Spain

Abstract

The work was carried out on Vitis vinifera, L. (cv. Macabeo) grafted onto 110 Ritcher rootstock and cultivated in two locations of the southern half of Spain: La Albuera (Badajoz) and Villarrobledo (Albacete), during 2016 and 2017. The soil of La Albuera is clay-loam texture, 1 m deep and 160 mm/m available water capacity (AWC); respect to climate is warm, cool nights and very dry according to the classification of [1]. The Villarrobledo soil is 0.75 m deep, silty-clay-loam texture and 135 mm/m AWC; the climate is very warm, cool nights and moderately dry climate. The study consisted in maintaining during two consecutive years and in both locations, the same hydric state of grapevine, which was evaluated by measurements of midday stem water potential, and comparing productive results obtained in the two places. Results derived from the analysis of yield components, as well as those derived of grape composition (total acidity, tartaric acid, malic acid, pH, potassium and soluble solids) show little variation between locations, instead great interannual variation among the parameters studied, so the "year-variety" effect seems to influence much more to the final result than the "locality-variety", for the case under study.
