Secuestro de carbono en sistemas silvopastoriles templados, Argentina.
(Ediciones INTA, 2018-10-31)El cambio climático global es uno de los principales problemas que enfrenta el mundo de hoy. Algunas manifestaciones de dicho cambio son el incremento de cerca de medio grado centígrado desde el siglo pasado, y cambios en ... -
Securing water for trees and people : possible avenues
(2011)In the context of water scarcity, threats on forest survival in drier areas, and thus of inevitable trade-off between man and nature for the use of water, this section addresses three main questions of importance for ... -
Sediment and nutrient deposition in different riparian forests and floods of the Middle Paraná River
(Wiley, 2019-10)Sedimentation processes are important to the dynamics of lowland fluvial systems and depend on the characteristics of floods and of riparian ecosystems. The few known studies for the Paraná River system analyzed only summer ... -
Seed dormancy QTL identification across a Sorghum bicolor segregating population
(2016)Pre-harvest sprouting (PHS) in Sorghum bicolor is one of the main constrains for its production in the central region of Argentina, as grain maturation often coincides with rainy or high environmental humidity conditions. ... -
Seed dormancy responses to temperature relate to Nothofagus species distribution and determine temporal patterns of germination across altitudes in Patagonia
(2015-08-26)Seeds integrate environmental cues that modulate their dormancy and germination. Although many mechanisms have been identified in laboratory experiments, their contribution to germination dynamics in existing communities ... -
Seed germination of five Prosopis shrub species (Fabaceae-Mimosoideae) from the Monte and Patagonia phytogeographic provinces of Argentina
(2017-12)The Patagonian species of the genus Prosopis exhibit distinctive features such as their shrub growth pattern. However, morphological or physiological differences among them have been poorly studied (e.g., germination). ... -
Seed priming induces biochemical changes in melon plants and increase salt tolerance
(Ediciones INTA, 2020-08)An experiment was conducted to evaluate the effect of priming on germination and initial growth of melon plants under salinity conditions. Two osmotic agents (NaCl and CaCl2) and two treatment durations (2 and 4 days) were ... -
Seed responses to temperature indicate different germination strategies among Festuca pallescens populations from semi-arid environments in North Patagonia
(Elsevier, 2019-04)Seed germination is one of the earliest phenotypes expressed by plants, and the accuracy to germinate in the correct time and place is essential for plant population fitness. Cues that regulate germination have been ... -
Seed yield determination of peanut crops under water deficit: Soil strength effects on pod set, the source–sink ratio and radiation use efficiency
(Elsevier, 2008-06-10)Peanut (Arachis hypogaea L.) production in Argentina is affected by frequent and unpredictable periods of water deficit that usually overlap the critical period for pod set of early sown crops. An indirect effect of water ... -
Seed-transmitted Epichloë sp. endophyte alleviates the negative effects of head smut of grasses (Ustilago bullata) on Bromus auleticus
(2017)Some grasses are co-infected by ‘castrator’ fungal pathogens, such as Ustilago bullata, and beneficial seed transmitted Epichlo€e endophytes that compete for plant photosynthates and flowers. Epichlo€e-infected (E+) and ... -
Seeding Resilient Restoration: An Indicator System for the Analysis of Tree Seed Systems
(MDPI, 2021-08-09)Achieving multi-million-hectare commitments from countries around the world to restore degraded lands in resilient and sustainable ways requires, among other things, huge volumes of tree planting material. Seed systems ... -
Seedling drought stress susceptibility in two deciduous Nothofagus species of NW Patagonia
(2010-06)The physiological capacities of seedlings to cope with drought may be subject to strong selective pressure in the context of future climate scenarios, threatening the regeneration and sustainability of forests. Characterization ... -
Seedling growth and water relations of three Cedrela species sourced from five provenances: response to simulated rainfall reductions
(2013-10)The effects of different simulated rainfall regimes on water relations, growth, and biomass production and allocation of five provenances of Cedrela fissilis, C. saltensis and C. balansae were assessed in a pot-grown ... -
Seguimiento de verdeos de raigrás anual en establecimientos ganaderos del sur de Corrientes
(EEA Mercedes, INTA, 2021-06-05)La provincia de Corrientes cuenta con ambientes aptos para la implantación de verdeos de invierno, especialmente el centro sur sobre campos de altura y monte de ñandubay. Los verdeos son una alternativa tecnológica válida ... -
