Ear reproductive development components associated with kernel set in maize: breeding effects under contrasting environments
(Elsevier, 2023-12)Context or problem: Kernel number per ear (KNE) is the main driver of improved grain yield per ear (GYE) in maize (Zea mays L.). Under non-limiting conditions, KNE responded to variations in ear developmental traits such ... -
Earliness per se variation in Argentine bread wheat varieties and mapping of QTLs in a recombinant inbred line population
(Springer, 2019-10)The occurrence of flowering time in wheat is affected not only by the vernalization and photoperiod response, but also by earliness per se (EPS). The effects of this trait facilitate the fine tunning of the life cycle for ... -
Early Adaptive Immune Responses in the Respiratory Tract of Foot-and-Mouth Disease Virus-Infected Cattle
(2013-03)Foot-and-mouth disease (FMD) is a highly contagious viral disease which affects both domestic and wild biungulate species. This acute disease, caused by the FMD virus (FMDV), usually includes an active replication phase ... -
Early detection of Ascochyta blight (Ascochyta rabiei) of chickpea by traditional PCR
(Elsevier, 2020-11-16)Ascochyta blight is the major disease affecting chickpea (Cicer arietinum) around the world. Since the first report of Ascochyta rabiei's isolation in Argentina in 2012, the pathogen has caused severe economic losses in ... -
Early exposure to and subsequent beef cattle performance with saline water
(2016-03)Two experiments were conducted to evaluate the impact of early life exposure to high salt water on later cattle performance with saline water. In Exp. 1, 24 cow/calf pairs were randomly assigned to one of two treatments: ... -
Early genetic consequences of defaunation in a large-seeded vertebrate-dispersed palm (Syagrus romanzoffiana)
(2017)Plant populations are seriously threatened by anthropogenic habitat disturbance. In particular, defaunation may disrupt plantdisperser mutualisms, thus reducing levels of seed-mediated gene flow and genetic variation in ... -
Early immune innate hallmarks and microbiome changes across the gut during Escherichia coli O157: H7 infection in cattle
(SpringerNature, 2020-12)The zoonotic enterohemorrhagic Escherichia coli (EHEC) O157: H7 bacterium causes diarrhea, hemorrhagic colitis, and hemolytic uremic syndrome (HUS) in humans. Cattle are primary reservoirs and EHEC O157: H7; the bacteria ... -
Early protection against foot-and-mouth disease virus in cattle using an inactivated vaccine formulated with Montanide ESSAI IMS D 12802 VG PR adjuvant
(Elsevier, 2014-04-17)Foot and mouth disease is an acute disease of cattle with a broad distribution around the world. Due to the fast spread of FMDV infections, control measures must be applied immediately after an outbreak, such as the use ... -
Early responses to Fe-deficiency distinguish Sorghum bicolor genotypes with contrasting alkalinity tolerance
(Elsevier, 2018-11)Soil alkalinity is a significant limitation to agricultural productivity and it is associated to several soil features, among them, Fe deficiencies. In this work, we explored the hypothesis that alkalinity tolerance in ... -
Early rooting and flooding tolerance in cuttings from a Populus deltoides full-sib family under greenhouse conditions
(Canadian Science Publishing, 2020-10-26)Populus deltoides is an important forest tree, with elite genotypes propagated mainly as unrooted dormant cuttings. Several areas where P. deltoides is planted periodically experience flooding episodes. The aims of this ... -
Early Selection for high spike fertility index in early generations increases grain number per unit area (and yield) of advanced breeding lines in bread wheat
(Wiley, 2023-03)Spike fertility index (a.k.a. fruiting efficiency) at maturity (FEm -grain number per spike/g spike chaff at maturity-) and spike harvest index (SHI -grain weight per spike/g spike chaff weight at maturity-) are considered ... -
Early stage litter decomposition across biomes
(Elsevier, 2018-02-22)Through litter decomposition enormous amounts of carbon is emitted to the atmosphere. Numerous large-scale decomposition experiments have been conducted focusing on this fundamental soil process in order to understand the ... -
Early water stress on growth, development and yield of high retention cotton
(University of Queensland, 2010)The Bollgard II cotton varieties, which contain two genes from Bacillus thuringiensis var kurstaki (Bt) that express proteins toxic to Helicoverpa spp. were recently released in Australia, and they have increased insect ... -
Early-stage findings in an experimental calf model infected with Argentinean isolates of Mycobacterium avium subsp. Paratuberculosis
(Elsevier, 2023-05)Mycobacterium avium subsp. paratuberculosis (MAP) is an important pathogen that causes granulomatous enteritis known as Johne’s disease or paratuberculosis (PTB). In this study an experimental model of calves infected with ... -
Eco-physiological bases of genetic gains of bread wheat yield in Mediterranean Spain during the 20th century
(Departament d'Enginyeria Agroforestal, Universitat de Lleida, 2009)Wheat breeding has played an important role in increasing yields during the 20th century. In general, the increase in yield was characterised by an exponential trend with the year of release of the cultivars: slow increase ... -
Eco-physiological processes underlying maize water use efficiency response to plant density under contrasting water regimes
(Elsevier, 2020-09)This study quantified maize (Zea mays L.) water use efficiency for grain yield (WUEg) in response to plant density under contrasting water regimes; and focused on relevant eco-physiologial processes underlying the responses ... -
Eco-physiology of maize crops under combined stresses
(Wiley, 2023-12)The yield of maize (Zea mays L.) crops depends on their ability to intercept sunlight throughout the growing cycle, transform this energy into biomass and allocate it to the kernels. Abiotic stresses affect these ... -
Ecofisiología del cultivo de maíz dulce (Zea mays l. Var. Saccharata) = Echophysiology of sweet corn (Zea mays L. var. saccharata)
(Asociación Argentina de Horticultura, 2017)Los maíces dulces y superdulces cuentan con un gen en homocigosis recesiva, cuya función es retardar o impedir la completa transformación de los azúcares solubles del grano en almidón, siendo esta la principal diferencia ... -
