    Litterfall dynamics (production, seasonality and nutrient composition) are key factors influencing nutrient cycling. Leaf litter characteristics are modified by species composition, site conditions and water availability. ...
  • Application of anti-transpirants temporarily alleviates the inhibition of symbiotic nitrogen fixation in drought-stressed pea plants 

    Aldasoro Galán, Joseba Upna; Larrainzar Rodríguez, Estíbaliz Upna; Arrese-Igor Sánchez, César Upna (Elsevier, 2019)   Artículo / Artikulua  OpenAccess
    Stomatal closure is one of the first plant responses under a water deficit situation. This leads to a decline in transpiration but also in the plant photosynthetic activity. Legume plants grown under symbiosis with rhizobium ...
