Halo-hydromorphism alters nitrogen fertilization responses of tall wheatgrass pastures: Capture and use of resources, tiller dynamics and forage production
(Wiley, 2024-03)Halo-hydromorphism limits productivity in approximately 100 million hectares worldwide. Tall wheatgrass (Thinopyrum ponticum) is a species widely used in these environments for its seeding potential, being the addition of ... -
Halotolerant bacteria isolated from extreme environments induce seed germination and growth of chia (Salvia hispanica L.) and quinoa (Chenopodium quinoa Willd.) under saline stress
(Elsevier, 2021-07)The aim of the study was to characterize halotolerant bacteria and to evaluate their plant growth promotion potential on chia and quinoa seedlings under saline stress. Isolated microorganisms were evaluated for nitrogen ... -
Halotolerant native bacteria Enterobacter 64S1 and Pseudomonas 42P4 alleviate saline stress in tomato plants
(Wiley, 2022-06)Salinity is one of the principal abiotic stresses that limit the growth and productivity of crops. The use of halotolerant plant growth-promoting rhizobacteria (PGPR) that increase the growth of salt-stressed crops is an ... -
Identification of QTLs for shoot and root growth under ionic–osmotic stress in Lotus, using a RIL population
(CSIRO Publishing, 2014-02-20)The genus Lotus includes a group of forage legume species including genotypes of agronomic interest and model species. In this work, an experimental hydroponic growth system allowed the discrimination of growth responses ... -
In vitro selection and characterization of buffelgrass somaclones with different responses to water stress
(2017-08)Buffelgrass is a forage grass that reproduces mainly by apomixis. In species with this reproduction mode, in vitro selection allows the incorporation of alternatives in a breeding program. The aims were to define a protocol ... -
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 ... -
Involvement of nitrate reductase (NR) in osmotic stress-induced NO generation of Arabidopsis thaliana L. roots
(Elsevier, 2010-01)Nitric oxide (NO) is undoubtedly a potential signal molecule in diverse developmental processes and stress responses. Despite our extensive knowledge about the role of NO in physiological and stress responses, the source ... -
Ion accumulation, water relations and osmotic adjustment in Atriplex argentina, A. crenatifolia, A. lampa and A. nummularia under saline conditions
(David Publishig, 2016-12)Salinity is a major stress that adversely affects growth and productivity in plants. There are species that tolerate this stress within the genus Atriplex. Four species, A. lampa, A. crenatifolia, A. nummularia and A. ... -
Leaf expansion in grasses under salt stress
(Elsevier, 2009-07)Restriction of leaf growth is among the earliest visible effects of many stress conditions, including salinity. Because leaves determine radiation interception and are the main photosynthetic organs, salinity effects on ... -
Morphological and physiological traits reveal differential salinity tolerance of two contrasting Glandularia cultivars
(Springer, 2020-09)In view of the current, continuous decrease of water availability, the need to explore new mitigation alternatives has given focus to salt-tolerant genotypes. The aim of this work was to study salt tolerance of two ornamental ... -
Morpho‐physiological, biochemical and isotopic response of tall wheatgrass populations to salt stress
(Wiley, 2020-12)Tall wheatgrass [Elymus elongatus subsp. ponticus (Podp.) Melderis] is a C3 grass native from dry or saline habitats in SE Europe. The aim of this study was to better understand response mechanisms of populations from ... -
Negative short-term salt effects on the soybean–Bradyrhizobium japonicum interaction and partial reversion by calcium addition
(CSIRO Publishing, 2013-09-05)The short-term (2 h) effects of salt stress (50 and 150 mM NaCl) on early events of soybean– Bradyrhizobium japonicum (rhizobia) interaction were analysed, determining the following parameters in root hair with or without ... -
Performance of alfalfa (Medicago sativa L.) populations to salinity stress under field condition in a semiarid environment
(Centro Regional Córdoba, INTA, 2021-09)The identification and evaluation of an alfalfa population with improved salinity tolerance on the field would provide some tools for dealing with salt stress. Screening populations in the field is difficult due to the ... -
Phenotypic characterization of a sorghum association panel for salinity stress tolerance : Key input for GWAS analysis
(Sociedad Argentina de Fisiología Vegetal, 2023-09-24)Salinity and alkalinity in soils represent a major problem worldwide due to their adverse effect on agriculture, in terms of productivity and sustainability Moreover, this problem is projected to worsen because of climate ... -
