Genetic and physical mapping of the earliness perse locus Eps - Am1 in Triticum monococcum identifies early flowering 3 (ELF3) as a candidate gene
(2016-07)Wheat cultivars exposed to optimal photoperiod and vernalization treatments still exhibit differences in heading time. This variation, known as earliness per se (Eps), is important for the fine-tuning of flowering and the ... -
Validación de sistemas de pronóstico del impacto de la fusariosis de la espiga en cultivares de trigo
(2016-07)En Argentina, el principal agente causal de la enfermedad conocida como fusariosis de la espiga de trigo (FET) es el hongo Fusarium graminearum (Schwabe) (teleomorfo Gibberella zeae (Schwein)). La FET es una enfermedad ... -
Efectividad de distintos pretratamientos en el análisis granulométrico de tres suelos contrastantes de la Región Pampeana = Effectiveness of different pretreatments on granulometry analysis for three contrasting soils of the Pampean Region
(Asociación Argentina de la Ciencia del Suelo, 2016-07)La granulometría es una de las características fundamentales del suelo, y su evaluación brinda información clave en la determinación de sus propiedades físicas. Sin embargo, existen divergencias metodológicas en los ... -
Physical and chemical variables analysis for clustering of soils in the longitudinal dunes of Sandy Pampa, Argentina
(Springer, 2016-08)The Sandy Pampa landscape was built on ancient dune-shaped landforms, which persist today and affect the characteristics of the soil in different sectors of the dunes. Based on their topographic position, different soils ... -
Carbon and water vapor balance in a subtropical pine plantation
(2016-10)Afforestation has been proposed as an effective tool for protecting primary and/or secondary forests and for mitigating atmospheric CO2. However, the dynamics of primary productivity differs between plantations and natural ... -
Supplementary Material Douglas-fir data [Conjunto de datos]
(2016-10)Supplementary information of the three Douglas-fir trials, family numbers, and pedigree data including identity information of trees, fathers, and mothers of the paper entitled: Identification and joint modeling of competition ... -
Mapping the soils of an Argentine Pampas region using structural equation modeling
(2016-11)Current digital soil mapping (DSM) methods have limitations. For instance, it is difficult to predict a large number of soil properties simultaneously, while preserving the relationships between them. Another problem is ... -
Identification and joint modeling of competition effects and environmental heterogeneity in three Douglas-fir (Pseudotsuga menziesii var. menziesii) trials
(2016-12)(Co)variance matrices for the assumed model, and thus the specification of the dispersion parameters, should take into account both the negative competition and the positive spatial correlations. In this context, we applied ... -
Catabolic response and phospholipid fatty acid profiles as microbial tools to assess soil functioning
(2016-12)Microbial properties may help to provide an integrated view of changes in soil functioning associated with soil management or soil status. The fatty acid profiles of membrane phospholipids (PLFA) can give the composition ... -
Flow cytometry : a useful tool measuring ploidy in Passiflora breeding programs
(2016-12)La citometría de flujo en plantas permite un análisis rápido y sencillo del material genético de las plantas. Para aplicar este método a plantas del género Passiflora, se pica finamente una porción de hoja y se pasa por ... -
Chromosome numbers and DNA content in some species of Mecardonia (Gratiolae, Plantaginaceae)
(2016-12)Cytogenetic characterization and determination of DNA content by flow cytometry of five species of Mecardonia Ruiz et Pavon, 1798 (Gratiolae, Plantaginaceae) was performed. This is the first study of nuclear DNA content ... -
Anuran responses to spatial patterns of agricultural landscapes in Argentina
(2016-12)Context: Amphibians are declining worldwide and land use change to agriculture is recognized as a leading cause. Argentina is undergoing an agriculturalization process with rapid changes in landscape structure. Objectives: ... -
