(Springer Nature, 2024-06)Flag leaf (FL) dimension has been reported as a key ecophysiological aspect for boosting grain yield in wheat. A worldwide winter wheat panel consisting of 261 accessions was tested to examine the phenotypical variation ... -
Natural Contamination with Mycotoxins Produced by Fusarium graminearum and Fusarium poae in Malting Barley in Argentina
(2018)Two of the most common species of toxin-producing Fusarium contaminating small cereal grains are Fusarium graminearum and F. poae; with both elaborating diverse toxins, especially deoxynivalenol (DON) and nivalenol (NIV), ... -
Natural distribution and phenotypic traits of Neltuma flexuosa var. depressa, a candidate taxon for the rehabilitation in the central arid region of Argentina
(Elsevier, 2023-02)Dryland rehabilitation in the central arid region of Argentina is urgently needed to reverse the current high levels of degradation. Neltuma flexuosa var. depressa, adapted to arid environments, gives it the potential to ... -
Natural grassland conversion to agriculture or pine plantations: Effects on soil methane uptake
(Wiley, 2024-01-30)Upland soils are the only known biological sink for methane (CH4) by methanotrophic bacteria consumption. This process is mainly limited by the diffusion processes related to the soil's physical characteristics, which can ... -
