Wheat Ppd-1 allelic combination modulates photoperiod sensitivity
(Sociedad Argentina de Fisiología Vegetal, 2018-11)ABSTRACT: a model linking Ppd-1 allelic composition to photoperiod response curve would allow replacing expensive and time consuming phenologic trials. In Ppd-1 near isogenic lines grown under different photoperiods we ... -
Wheat pre-anthesis development as affected by photoperiod sensitivity genes (Ppd-1) under contrasting photoperiods
(2018-01)Fine tuning wheat phenology is of paramount importance for adaptation. A better understanding of how genetic constitution modulates the developmental responses during pre-anthesis phases would help to maintain or even ... -
Wheat spike fertility : inheritance and relationship with spike yield components in early generations
(2015)In wheat, grain number is considered as the product of spike dry weight (SDW) and the number of grains per unit of SDW, that is an indicator of spike fertility (SF). The aim of this study was to determine the heritability ... -
Wheat yield progress and stability during the last five decades in Argentina
(Elsevier, 2021-07)Improvement of grain yield (GY) at farm level, which is closely related to GY potential, seems to be the main alternative to increase wheat (Triticum aestivum L) production. The aim of current research was to assess the ... -
When neglected species gain global interest: Lessons learned from quinoa's boom and bust for teff and minor millet
(Elsevier, 2022-03)Until recently, many so-called neglected and underutilized species (NUS) were not present in global markets despite playing a pivotal role in the local livelihoods in their places of origin. Today, some NUS receive substantial ... -
When we cannot have it all: Ecosystem services trade-offs in the context of spatial planning
(2017)Spatial planning has to deal with trade-offs between various stakeholders’ wishes and needs as part of planning and management of landscapes, natural resources and/or biodiversity. To make ecosystem services (ES) trade-off ... -
Where are the males? The influence of bottom-up and top-down factors and sociability on the spatial distribution of a territorial ungulate
(Springer, 2022-01)The factors that regulate the abundance and distribution of wild herbivores are key components of a species’ ecology and include bottom-up and top-down mechanisms, as well as aspects related to social organization. In ... -
Where to find structural grade timber: a case study in ponderosa pine based on stand and tree level factors
(Elsevier, 2020-03-01)Using portable acoustic tools, measurements of dynamic modulus of elasticity (Ed) were made in standing ponderosa pine (Pinus ponderosa (Dougl. ex Laws)) trees (n =437) growing in 22 stands encompassing the range of ... -
Which are important targets in development of S. aureus mastitis vaccine?
(2015-06)Staphylococcus aureus represents one of the leading causes of mastitis in dairy cows worldwide. S. aureus IMI have variable outcomes due to virulence of the strain involved, immune defenses of the host, and by antibiotic ... -
White muscle disease in three selenium deficient beef and dairy calves in Argentina and Uruguay
(Centro de Ciências Rurais, Universidade Federal de Santa Maria, 2018-05)White muscle disease (WMD), nutritional myodegeneration or enzootic muscular dystrophy, is a nutritional condition associated with selenium and/or vitamin E deficiency in ruminants. These elements are constituents of the ... -
Whole cluster and dried stem additions effects on chemical and sensory properties of Pinot Noir wines over two vintages
(American Society for Enology and Viticulture, 2020-08)The effect of whole cluster at 50% (50% WC) and 100% additions (100% WC), as well as that of Dried stems (DS) on Pinot noir wines from the Edna Valley AVA of California (USA) were investigated over two consecutive vintages ... -
Whole genome resequencing and custom genotyping unveil clonal lineages in ‘Malbec’ grapevines (Vitis vinifera L.)
(Springer Nature, 2021-04-08)Grapevine cultivars are clonally propagated to preserve their varietal attributes. However, genetic variations accumulate due to the occurrence of somatic mutations. This process is anthropically influenced through plant ... -
Whole Genome Sequence-Based Analysis of Bovine Gammaherpesvirus 4 Isolated from Bovine Abortions
(Multidisciplinary Digital Publishing Institute, MDPI, 2024-05-08)Bovine gammaherpesvirus 4 (BoGHV4) is a member of the Gammaherspivirinae subfamily, Rhadinovirus genus. Its natural host is the bovine, and it is prevalent among the global cattle population. Although the complete genome ... -
Whole plant open chamber to measure gas exchange on herbaceous plant
(2016)Much of our understanding about CO2 and H2O gas exchange in plants has been gained from studies at leaf level. Extrapolation of results to whole plant is difficult and not always accurate. In order to overcome this limitation, ... -
Why biodiversity increases after variable retention harvesting: A meta-analysis for southern Patagonian forests
(2016-06-01)Effects of forest harvesting on biodiversity can be varied and complex to understand. We provide a meta-analysis of 553 studies plants, insects and birds to identify the general responses to Variable Retention harvesting ... -
Why do Pinus species have different growth dominance patterns than Eucalyptus species? A hypothesis based on differential physiological plasticity
(Elsevier, 2011-03-15)It has been observed that Eucalyptus stands show high growth dominance levels while Pinus stands show null or low growth dominance levels. We hypothesized that this differential behaviour is linked to a higher degree of ... -
Widespread and major losses in multiple ecosystem services as a result of agricultural expansion in the Argentine Chaco
(Wiley, 2020-09-09)1.Where agriculture expands into tropical and subtropical forests, social–ecological impacts are typically strong. However, where and how frontier development impacts on ecosystem functioning and services is often unclear, ... -
Wild and cultivated potato species diversity, taxonomy, and conservation
