(Asociación Argentina Ciencia del Suelo (AACS), 2022-11-15)El mantenimiento y/o incremento del contenido de carbono orgánico ( y nitrógeno Nt en suelo es de gran relevancia para la conservación de propiedades biológicas, químicas y físicas del mismo, como así también para mitigar ... -
Stomatal micromorphology in a complex of Mimosa section Mimosa (Fabaceae)
(Springer, 2021-04-20)The genus Mimosa Linnaeus (Leguminosae) comprises more than 530 species, being one of the most diversified genera in the family. A vast morphologic variability has been described at all infrageneric levels. Considering ... -
Storage lipids and proteins of Euterpe edulis seeds
(Sociedad Latinoamericana de Microscopía Electrónica y Centro Regional de Investigaciones Científicas y Tecnológicas (Mendoza, Argentina), 2009)Comparative studies on fatty acid and protein composition of the endosperm and embryo of palmito (Euterpe edulis Martius) were conducted using gas-liquid chromatography and sodium dodecyl sulfate– polyacrylamide gel ... -
A strain of Bacillus subtilis subsp. subtilis shows a specific antagonistic activity against the soil-borne pathogen of onion Setophoma terrestris
(2015)Pink Root is among the major diseases of onion and its causal agent, Setophoma terrestris, is one of the most severe pathogens in soils of tropical and subtropical climates. The management of Pink Root is difficult and the ... -
Strengthening the biogas sector of Ethiopia through international collaboration: the case of Digital Global Biogas Cooperation (DiBiCoo)
(IOP Publishing, 2022)Even though biogas technology was introduced in Ethiopia in 1957, the technology is still in its infancy stage with more than 98 % of biogas plants installed in Ethiopia at a small- scale level and used for cooking and ... -
Stress response at different ages of weaning in cattle
(Infogain Publication, 2019-02)Weaning is an inherent husbandry practice in cow-calf beef production systems that impose physical, psychological, and nutritional stressors on calves. In order to characterize the main stressors and corresponding stress ... -
Stress-induced expression of IPT gene in transgenic wheat reduces grain yield penalty under drought
(Springer, 2021-05)Background: The heterologous expression of isopentenyl transferase (IPT) under the transcriptional control of the senescence-associated receptor-like kinase (SARK) promoter delayed cellular senescence and, through it, ... -
