Modeling leaf maximum net photosynthetic rate of Festuca pallescens, the dominant perennial grass of Patagonian pine-based silvopastoral systems
(2011-09)
The integrated relationship in a simple mechanistic model between the critical environmental factors controlling leaf photosynthesis of understory species would be a useful tool to optimize the management of the silvopastoral ...
Effect of stand density and pruning on growth of ponderosa pines in NW Patagonia, Argentina
(2010-03)
Due to the lack of knowledge about ponderosa pine performance under silvopastoral systems (SPS) conditions, the objective of this study was to determine the effect of stand density and pruning on the growth magnitude of ...
Strawberry cultivars performance in contrasting cropping conditions in Tucumán (Argentina) = Comportamiento de cultivares de fresa en condiciones de cultivo contrastantes en Tucumán (Argentina)
(Facultad de Agronomía y Zootecnia, Universidad Nacional de Tucumán, 2023-06)
Strawberry (Fragaria x ananassa Duch.) production in Argentina takes place in a wide environmental range, being characterized by the coexistence of different production systems, limitations to technology access by small-scale ...
Effects of climate on the radial growth of mixed stands of Nothofagus nervosa and Nothofagus obliqua along a precipitation gradient in Patagonia, Argentina
(Elsevier, 2022-08)
Climate models for North Patagonia in Argentina project dryer conditions, due to a decrease in mean precipitation combined with an increase in mean temperatures. The temperate mixed Nothofagus forest, which exists along a ...
Functional characterization of DcMYB11, an R2R3 MYB associated with the purple pigmentation of carrot petiole
(Springer, 2023-07)
The accumulation of anthocyanin pigments can exhibit different patterns across plant tissues and crop varieties. This variability allowed the investigation of the molecular mechanisms behind the biosynthesis of these ...
Occurrence and duration of phenological phases of Freesia x hybrida grown at different planting dates
(Sociedade Brasileira de Floricultura e Plantas Ornamentais (SBFPO), 2023-06)
Freesia (Freesia x hybrida) is one of the most cultivated species of cut flowers, ranking sixth in the international market. Pheno- logical processes occurring during the crop cycle are controlled by endogenous mechanisms ...
A new model formulation for host depletion in parasitoids
(Elsevier, 2023-01)
A new model of host depletion in the functional response of parasitoids is presented. Most existing models describe the dynamics of prey consumption as a sequential-memoryless/Markovian process of searching for, handling, ...
Rickettsia spp., Ehrlichia sp. and Candidatus Midichloria sp. associated to ticks from a protected urban area in Buenos Aires City (Argentina)
(Springer, 2022-01)
The aim of this study was to determine the infection with Rickettsiales in ticks and birds from the main protected urban area of Buenos Aires City (Argentina). One Amblyomma aureolatum (0.2%) and one Ixodes auritulus (0.1%) ...
Direct determination of tyrosine and tryptophane enantiomers in pumpkin (Cucurbita moschata) by HPLC-UV/Vis: Effect of cooking treatment on enantiomers profile
(Elsevier, 2023-09)
An analytical method to determine the content of tryptophan (Trp) and tyrosine (Tyr) enantiomers in pumpkin (Cucurbita moschata) is developed and validated. The method consists of a sample preparation procedure with a ...
Storage Stability of Arauco Virgin Olive Oil: Evolution of Its Quality Parameters and Phenolic and Triterpenic Compounds under Different Conservation Conditions
(MDPI, 2023-04)
The storage conditions are very critical to minimize hydrolytic and oxidative reactions of virgin olive oils (VOOs). These reactions are logically influenced by the composition of the VOO, so that each variety may have a ...
