Fertilidad en plantas apomícticas facultativas de Cenchrus ciliaris L.
(Sociedad Argentina de Botánica, 2021-09-06)Cenchrus ciliaris L. es una especie forrajera perenne de crecimiento primavero-estival. Es alotetraploide segmental y se reproduce por apomixis apospórica seguida de pseudogamia. Las plantas sexuales son raras y escasas y ... -
Potential sources of sexuality in Cenchrus ciliaris L.: Seed fertility, environment and its implication in plant breeding
(Centro Regional Córdoba, INTA, 2021-09-13)Cenchrus ciliaris L. is an aposporic and pseudogamous apomictic species, and fully sexual plants are very rare or absent. Fertility, which seems to be influenced by environmental factors, is a character of interest for ... -
Formulación y propiedades de biopolímero de recubrimiento para semillas de maní (Arachis hypogaea L.)
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2021-06-30)En este trabajo se presenta el diseño de una biopelícula de recubrimiento biodegradable, formulada con macromoléculas naturales como almidón, proteína y glicerol para ser aplicada sobre semillas de maní, a fin de aumentar ... -
Bioprospección de bacterias endófitas del maní y su potencial actividad biocontroladora del agente causal del carbón, Thecaphora frezii.
(Asociación Argentina de Microbiología, 2021-09-15)El maní es considerado una importante leguminosa a nivel mundial. Argentina es la principal exportadora mundial de maní manufacturado de alta calidad, concentrándose el 95% de la producción en la provincia de Córdoba. El ... -
Lead uptake and translocation pathways in soybean seedlings: the role of ion competition and transpiration rates
(Springer, 2021-01-06)Glycine max (L.) Merr. (soybean) crop plants have been found to have high lead (Pb) levels in aerial organs; however, knowledge about the processes involved in the incorporation, and subsequent translocation and accumulation ... -
Assessment of lead tolerance on Glycine max (L.) Merr. at early growth stages
(Springer, 2021-01-11)Lead (Pb) contamination of agricultural soils, and subsequently of crops, has been widely reported. Soybean (Glycine max (L.) Merr.) has been indicated as a plant that accumulates Pb, even in soils that do not exceed the ... -
A proposed role for endomembrane trafficking processes in regulating tonoplast content and vacuole dynamics under ammonium stress conditions in Arabidopsis root cells
(Taylor and Francis, 2021-05-06)Ammonium (NH4+) stress has multiple effects on plant physiology, therefore, plant responses are complex, and multiple mechanisms are involved in NH4+ sensitivity and tolerance in plants. Root growth inhibition is an important ... -
Plant Tolerance Mechanisms to Soil Salinity Contribute to the Expansion of Agriculture and Livestock Production in Argentina
