Feasibility of lowering soybean planting density without compromising nitrogen fixation and yield
(American Society of Agronomy, 2014)Adjusting soybean [Glycine max (L.) Merrill] density can be critical to reduce inter-plant competition for water, nutrients, and sunlight, and to increase intercepted radiation, photosynthesis, and biomass production. The ... -
Wild halophytic species as forage sources: key aspects for plant breeding
(Wiley; British Grassland Society; European Grassland Federation, 2019-02-20)The use of wild halophytic species as forage resources in saline environments has gained increasing attention. Argentina ranks third in area of saline soils in the world, with a third of its territory showing various degrees ... -
Silencing of the tomato phosphatidylinositol‐phospholipase C2 (SlPLC2) reduces plant susceptibility to Botrytis cinerea
(Wiley, 2016-12)The tomato [Solanum lycopersicum (Sl)] phosphatidylinositol‐phospholipase C (PI‐PLC) gene family is composed of six members, named SlPLC1 to SlPLC6, differentially regulated on pathogen attack. We have previously shown ... -
Differential characteristics of photochemical acclimation to cold in two contrasting sweet sorghum hybrids
(Wiley; Scandinavian Plant Physiology Society, 2016-08)Sweet sorghum has a photosynthetic system which is highly sensitive to cold stress and hence strongly limits its development in temperate environments; therefore, the identification of key exploitable cold tolerance traits ... -
Germination characteristics of five coexisting neotropical species of Acacia in seasonally dry Chaco forests in Argentina
(Wiley, 2017-04)At a regional scale, habitat heterogeneity can play a very important role in allowing the coexistence of species through their specialization in the use of patches differing in environmental conditions. Here, we explore ... -
Salt tolerance variability among stress‐selected Panicum coloratum cv. Klein plants
(Wiley; British Grassland Society; European Grassland Federation, 2016-11)This work assessed intracultivar variability for salt tolerance within Panicum coloratum cv. Klein, explored some physiological parameters potentially associated with it and evaluated the contribution of cell division and ... -
Nutrient deficiency and hypoxia as constraints to Panicum coloratum growth in alkaline soils
(Wiley; British Grassland Society; European Grassland Federation, 2017-12)Alkaline and saline–alkaline soils impose severe restrictions on plant growth. Panicum coloratum var. coloratum is a perennial C4 forage grass widely used in tropical and subtropical environments. Published information on ... -
Glutathione, a key compound for As accumulation and tolerance in soybean plants treated with AsV and AsIII
(Elsevier, 2019-06)Despite soybean (Glycine max L.) is often cultivated in areas contaminated with arsenic (As) which causes deleterious effects on its growth, little is known about tolerance mechanisms in response to As exposure. In particular, ... -
Interspecific hybridization improves the performance of Lotus spp. under saline stress
(Elsevier, 2019-06)Salinity is one of the most frequent limiting conditions in pasture production for grazing livestock. Legumes, such as Lotus spp. with high forage quality and capable of adapting to different environments, improves pasture ... -
Malondialdehyde content as a potential biochemical indicator of tolerant Cenchrus ciliaris L. genotypes under heat stress treatment
(Wiley, 2012-09)Buffel grass (Cenchrus ciliaris L.) is an important forage grass in arid and semiarid regions. As part of a genetic improvement programme, four genotypes [Biloela (Bl), Americana (Am), Texas (Tx) and Sexual (Sx)] were ... -
Diversidad e infectividad de hongos micorrícicos arbusculares nativos provenientes de algarrobales del Parque Chaqueño argentino con características edafoclimáticas contrastantes
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2018)En ambientes severos, la presencia de hongos micorrícicos arbusculares (HMA) es clave para la supervivencia de las plantas y el balance ecosistémico. El objetivo de este trabajo fue caracterizar los hongos micorrícicos ... -
Day length modulates precocity and productivity through its effect on developmental rate in Origanum vulgare ssp.
(Elsevier, 2017-04)In Origanum spp. knowledge about mechanisms controlling development and growth in response to environmental factors such as temperature and photoperiod, is critical to improve management practices and varietal selection ... -
A bacterial endophyte from apoplast fluids protects canola plants from different phytopathogens via antibiosis and induction of host resistance
(American Phytopathological Society, 2019-03)Endophytic bacteria colonize inner plant tissues and thrive at the apoplast, which is considered its main reservoir. Because this niche is the place where the main molecular events take place between beneficial and pathogenic ... -
Assessing spatial genetic structure from molecular marker data via principal component analyses: a case study in a Prosopis sp. fores
(Scientific Research Publishing, 2014-01)Advances in genotyping technology, such as molecular markers, have noticeably improved our capacity to characterize genomes at multiple loci. Concomitantly, the methodological framework to analyze genetic data has expanded, ... -
Morphological diversity of populations of the genus Prosopis in the semiarid Chaco of northern Cordoba and southern Santiago Del Estero
