La creciente demanda de agua en agricultura hace que la optimación de este recurso sea cada vez más necesaria. Un ejemplo es el caso del cultivo del olivar, cuya superficie regada ha aumentado notablemente en los últimos años. Esto hace que se estén buscando actualmente métodos más precisos para el manejo del riesgo de este cultivo,...

The effects of olive waste biochar and green compost as soil amendments on soil physical properties, as well as on physiological parameters and yield of a super-intensive olive crop cultivated under deficit irrigation conditions, were investigated in south-west Spain during the 2021 growing season. Thus, soils were amended with 40 t ha−1 of...

Se ha realizado una plantación experimental con Pinus halepensis micorrizados con las especies fúngicas Pisolithus tinctorius, Suillus mediterraneensis, S. collinitus y Rhizopogon roseolus. El objetivo fue mejorar las técnicas de restauración de la cubierta vegetal en los ecosistemas semiáridos del Sureste Peninsular, principalmente en la...

Redox regulation plays a central role in the adaptation of chloroplast metabolism to light. Extensive biochemical analyses in vitro have identified f-type thioredoxins (Trxs) as the most important catalysts for light-dependent reduction and activation of the enzymes of the Calvin–Benson cycle. However, the precise function of type f Trxs in...

In this work we tested techniques suitable for a future validation of the RATP model to simulate transpiration and photosynthesis of mature olive trees under field conditions. Canopy architecture was characterised with an electromagnetic 3D digitiser and the software 3A. Although the capability of the software to deal with big data sets has to...

– Influence de l'irrigation partielle du sol sur les paramètres des relations hydriques de l'olivier. Une comparaison de l'irrigation goutte à goutte avec l'irrigation en cuvette a été conduite sur oliviers 'Manzanilla' âgés de 30 ans plantés à 7 m 5 m dans un verger du sud-ouest de l'Espagne. À la fin de la saison sèche de 1998, nous avons...

The presence of fruits provokes significant modifications in plant water relations and leaf gas exchange. The underlying processes driving these modifications are still uncertain and likely depend on the water deficit level. Our objective was to explain and track the modification of leaf-water relations by the presence of fruits and water...
