    • Evaluation of the agronomic performance of 'Syrah' and 'Tempranillo' when grafted on 12 rootstocks 

      Marín Ederra, Diana Upna; García, R.; Eraso, J.; Urrestarazu Vidart, Jorge Upna; Miranda Jiménez, Carlos Upna; Royo Díaz, José Bernardo; Abad Zamora, Francisco Javier Upna; Santesteban García, Gonzaga Upna (Julius Kühn Institute (JKI), 2019)   Artículo / Artikulua  OpenAccess
      Beyond pest resistance, rootstocks significantly influence the performance of grapevine varieties. However, the effect of the rootstock is strongly affected by its interaction with the environment, and it is therefore ...
    • Integration of expert knowledge in the definition of Swiss pear core collection

      Core collections (CCs) constitute a key tool for the characterization and management of genetic resources (GR). When the institutions involved in GR preservation decide to define a CC, they frequently prefer to select ...
    • Sampling stratification using aerial imagery to estimate fruit load in peach tree orchards 

      Miranda Jiménez, Carlos Upna; Santesteban García, Gonzaga Upna; Urrestarazu Vidart, Jorge Upna; Loidi Erviti, Maite Upna; Royo Díaz, José Bernardo Upna (MDPI, 2018)   Artículo / Artikulua  OpenAccess
      A quick and accurate sampling method for determining yield in peach orchards could lead to better crop management decisions, more accurate insurance claim adjustment, and reduced expenses for the insurance industry. Given ...
    • A water content continuous monitoring of grapevine xylem tissue using a portable low-power cost-effective FMCW radar 

      Quemada Mayoral, Carlos Upna; García González, Cebrián Upna; Iriarte Galarregui, Juan Carlos Upna; Marín Ederra, Diana Upna; Gastón Beraza, Diego; Miranda Jiménez, Carlos Upna; Gonzalo García, Ramón Upna; Maestrojuán Biurrun, Itziar Upna; Santesteban García, Gonzaga Upna; Ederra Urzainqui, Íñigo Upna (IEEE, 2019)   Artículo / Artikulua  OpenAccess
      This paper presents the real-time monitoring of a grapevine’s water content that flows up through the xylem tissue by means of a frequency-modulated continuous-wave (FMCW) radar. The application of an optimization process, ...
