Utilización del potencial hídrico del tallo para el manejo del riego del olivar en seto: metodología y umbrales durante la primavera (brotación-endurecimiento del hueso) y el otoño (síntesis de aceite) [PDF]

, 2021
El estado hídrico de los árboles se puede medir con diversos métodos. El más utilizado y fiable es el potencial hídrico del tallo (Ψtallo). Se mide introduciendo un brote con un par de hojas en una cámara de presión (Scholander). Se utiliza en experimentación, en el manejo del riego y para la determinación de los valores umbrales necesarios para el ...

Maslinic Acid Enhances Signals for the Recruitment of Macrophages and Their Differentiation to M1 State

Evidence-Based Complementary and Alternative Medicine, Volume 2015, Issue 1, 2015., 2015
The inflammatory process is involved in the genesis and evolution of different diseases like obesity, cardiovascular disease, and cancer. Macrophages play a central role in inflammation. In addition, they can regulate some stages of cancer development. Macrophages can polarize into M1 or M2 functional phenotype depending on the cytokines present in the

Drivers of plant phenolic concentration across global drylands

Journal of Ecology, Volume 114, Issue 1, January 2026.
This study advances the understanding of how biotic and abiotic stressors shape plant defence strategies in global drylands. The findings shed novel insights about how plant secondary metabolites and their associated functions shift in response to changes in climate and grazing pressure, two key global change drivers with significant implications for ...

Natural variation of response to glyphosate in Sinapis alba (Brassicaceae): Physiological effects, shikimate accumulation and genetic mechanisms

Weed Research, Volume 65, Issue 5, September/October 2025.
Abstract Glyphosate is the most widely used herbicide worldwide, and glyphosate‐resistant weeds have increased globally. Resistance mechanisms, including target‐site resistance (TSR) and non‐target‐site resistance (NTSR), are well documented, but their extent and importance are poorly understood among biotypes. This study examines the natural variation

Grazing Modulates the Multiscale Spatial Structure of Dryland Vegetation

Global Change Biology, Volume 31, Issue 7, July 2025.
We studied how grazing pressure affects plant spatial patterns in drylands by using satellite images, field plant size and abundance data, and a mathematical model. We found that increasing grazing pressure has opposite effects on vegetation spatial structure to those of aridity, which might be explained by the fact that grazing decreases plant size ...

Nitro‐fatty acids‐mediated nitroalkylation modulates fine‐tuning catalase antioxidant function during salinity stress in plants

Protein Science, Volume 34, Issue 3, March 2025.
Abstract Nitro‐fatty acids (NO2‐FAs) are novel molecules resulting from the interaction of unsaturated fatty acids and nitric oxide (NO) or NO‐related molecules. In plants, it has recently been described that NO2‐FAs trigger a powerful antioxidant and defense response against stressful situations, the induction of the heat‐shock response (HSR), and ...

Respuesta fisiológica y agronómica del olivar en seto (cv. Arbequina) a la orientación de filas y al ancho de calle: relación entre la producción y calidad del aceite y la radiación interceptada

, 2022
En las últimas dos décadas, los productores han plantado olivares en seto para lograr la mecanización de la poda y en especial de la cosecha, reducir los costes de mano de obra y permitir intervenciones de manejo rápidas y oportunas. Los olivares se desarrollaron en ausencia del conocimiento científico, sobre el diseño óptimo de la estructura de la ...
