Rhizobium leguminosarum biovar viciae genotypes interact with pea plants in developmental responses of nodules roots and shoots
2007
International audience; The variability of the developmental responses of two contrasting cultivars of pea (Pisum sativum) was studied in relation to the genetic diversity of their nitrogen-fixing symbiont Rhizobium leguminosarum bv. viciae. A sample of 42 strains of pea rhizobia was chosen to represent 17 genotypes predominating in indigenous rhizobial populations, the genotypes being defined by the combination of haplotypes characterized with rDNA intergenic spacer and nodD gene regions as markers. We found contrasting effects of the bacterial genotype, especially the nod gene type, on the development of nodules, roots and shoots. A bacterial nod gene type was identified that induced very…
Hirnantian glacial and deglacial record in SW Djado Basin (NE Niger).
2007
Pluridisciplinary fieldwork highlights features generated by an extended ice-sheet in the Djado Basin during the Hirnantian. Two glacial palaeovalley systems associated with glacial pavements and separated by thin glaciomarine interstadial series are revealed. Rigid glacial pavements characterised by abrasion erosion are differentiated from soft glacial pavements characterised by soft-bed deformation. Glacial pavements are associated with subglacial bedforms such as megaflutes, flutes and meltwater channels. They are also associated with clastic dykes and glaciotectonic structures such as deformed flutes, subglacial folds and duplex structures. This record demonstrates that ice was warm-bas…

Ex situ evaluation of grain yield in local landraces of faba bean (Vicia faba L.) from Serbia
2013
International audience; Faba bean (Vicia faba L.) originated in Central Asian centre of diversity. Faba bean is one of the most ancient cultivated plant species in the world, along with several other grain legumes, and cereals. Numerous archaeobotanical fi ndings, supported by rich linguistic evidence (1), witness its early and rapid distribution during Neolithic from Near East to Europe, North Africa and Central and East Asia and an important role it had in everyday diets of the ancestors of modern Old World nations. Today, faba bean is one of the most important annual legume crops for human consumption, animal feeding and for non-food purposes. Conservation and sustainable utilisation of …
In situ preservation of local landraces of faba bean (Vicia faba L.) and utilisation of their food products in central regions of Serbia
2013
Today, faba bean (Vicia faba L.) in Serbia is almost completely replaced with Phaseolus beans and has become a neglected crop with no official data. A recently launched action of the Institute of Field and Vegetable Crops and the Faculty of Agriculture in Novi Sad is aimed at the identification of the regions in Serbia where faba bean, known in Serbian as bob, could still be found. This was essentially enhanced by the multilateral project ECO-NET 18817 Search for new genetic variability in pea (Pisum sativum) and faba bean (Vicia faba L.) to support the development of sustainable agricultures, with duration in 2008 and 2009 and involving partners from France, Bulgaria, Russia, Serbia and Re…
Towards conservation of the local landraces of faba bean (Vicia faba) in Serbia.
2010
International audience; Today, faba bean (Vicia faba L.) in Serbia is almost an extinct crop, without official data on harvested area or production for decades. However, faba bean survived in certain parts of the country, especially along the rivers Southern and Great Morava, in the centre, and in Backa, in the north. In these parts, faba bean is cultivated mostly to suit one's own needs and sporadically is brought to green markets. It is grown as a garden crop, with sowing either in spring or during winter in order to achieve faster growth in comparison to the first schedule. First steps towards the conservation of faba bean local landraces in Serbia have been made within the multilateral …

Mikrobioloģisko augu mēslošanas līdzekļu ietekme uz augsnes mikrobiotu un Vicia faba ražību
2018
Lauka pupa (Vicia faba) ir plaši audzēts kultūraugs, kuru izmanto pārtikā, lauksaimniecībā un lopkopībā. Ražas paaugstināšanai izmantoto mēslojumu sastāvs var ietekmēt ne tikai ražas apjomu, bet arī augsnes mikrobiotu. Šajā darbā aplūkots, kā mēslošanas līdzekļi ietekmē augsnes mikrobiotu, novērtējot mikroorganismu daudzuma izmaiņas, un lauka pupas ražību, novērtējot augšanu un iegūtās sēklas parametrus, piem., daudzumu, proteīna saturu. Iegūtie rezultāti uzrāda sēņu daudzuma augsnē atkarību no mēslošanas līdzekļiem. Savukārt uz baktēriju daudzumu nav novērojama būtiska mēslošanas līdzekļu ietekme. Mēslošanas līdzekļiem ir liela nozīme lauka pupas attīstībā un ražā, tomēr to ietekmē arī aug…

Representações sociais, sens pratique, poder simbólico e o processo de construção do ser docente
2019
A partir de las elaboraciones teóricas de los fundadores del campo de investigación de las representaciones sociales, se pretende avanzar en la construcción de un diálogo entre esta teoría y la praxis social de Pierre Bourdieu, centrándose en la relación entre las representaciones sociales, la praxis sensorial (como manifestación del hábito) y el poder simbólico, dimensión ausente en el modelo moscoviciano. La base empírica a partir de la cual se desarrollan las reflexiones presentes en este artículo se apoya en investigaciones realizadas sobre el proceso de construcción del ser docente, en la realidad de algunas ciudades del nordeste brasileño. En este sentido, se destaca lo que se cree qu…
