    • Isotopic composition of maize as related to N-fertilization and irrigation in the Mediterranean region 

      Lasa Larrea, Berta Upna; Irañeta, Iosu; Muro Erreguerena, Julio Upna; Irigoyen Iriarte, Ignacio Upna; Aparicio Tejo, Pedro María Upna (Escola Superior de Agricultura "Luiz de Queiroz", Universidade de São Paulo, 2011)   Artículo / Artikulua  OpenAccess
      Nitrate leaching as a result of excessive application of N-fertilizers and water use is a major problem of vulnerable regions. The farming of maize requires high N fertilization and water inputs in Spain. Isotopic ...
    • Leaf δ15N as a physiological indicator of the responsiveness of N2-fixing alfalfa plants to elevated CO2, temperature and low water availability 

      Ariz, Idoia Upna; Cruz, Cristina; Neves, Tomé; Irigoyen, Juan J.; García Olaverri, Carmen Upna; Nogués, Salvador; Aparicio Tejo, Pedro María Upna; Aranjuelo Michelena, Iker (Frontiers Media, 2015)   Artículo / Artikulua  OpenAccess
      The natural 15N/14N isotope composition (δ15N) of a tissue is a consequence of its N source and N physiological mechanisms in response to the environment. It could potentially be used as a tracer of N metabolism in plants ...
    • Leaves play a central role in the adaptation of nitrogen and sulfur metabolism to ammonium nutrition in oilseed rape (Brassica napus) 

      Coleto, Inmaculada; Peña, Marlon de la; Rodríguez Escalante, Jon; Bejarano, Iraide; Glauser, Gaëtan; Aparicio Tejo, Pedro María Upna; González Moro, María B.; Marino Bilbao, Daniel Upna (BioMed Central, 2017)   Artículo / Artikulua  OpenAccess
