DYNAMICS OF ACCUMULATION AND PARTITIONING OF DRY MATTER AND FRUCTO-OLIGOSACCHARIDES IN PLANT FRACTIONS OF FORAGE CEREALS
No full textDuring growth, several cereals store significant amounts of fructo-oligosaccharides (FOS), which have important prebiotic properties. Cereal forage crops are also essential components of many Mediterranean agricultural systems, although little information is available on their dynamics of accumulation and partitioning of dry matter and FOS during growth. Oat (Avena sativa L., cv. 'Flavia' and cv. 'Genziana'), emmer wheat (Triticum dicoccum Schrank, cv. 'Giovanni Paolo'), barley (Hordeum vulgare L., cv. 'Diomede') and triticale (xTriticosecale Wittmack, cv. 'Rigel') were investigated for their synthesis of FOS, with a view to development of management approaches for harvesting high-quality forage, and to determine whether these species can be used as natural sources of FOS for commercial use. The study was conducted at Foggia (Italy) and Bella (Potenza, Italy) over two growing seasons (2008-2009; 2009-2010). Dry-matter accumulation and FOS contents were determined for plant fractions from heading to kernel-hard stages. There were large variations across these species for dry-matter partitioning and dry-matter yield (greatest for triticale: 1.24 kg m(-2)), and for FOS levels of total plants and plant fractions. Emmer wheat and triticale showed greater FOS production (52.0, 41.1 gm(-2), respectively). Barley, emmer wheat and triticale showed higher FOS levels in total plants (4.11%, 5.93%, 4.33% dry matter, respectively). Barley, emmer wheat and triticale appear to be the most interesting species for production of forage biomass rich in FOS and as natural FOS sources for industrial use

Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
