    NORTH AMERICAN CONTINENT - A NEW SOURCE OF WILD LACTUCA SPP. GERMPLASM VARIABILITY FOR FUTURE LETTUCE BREEDING

    Full text link
    In the years 2002-2008, missions were undertaken in the USA and Canada to search for wild and weedy Lactuca species. Altogether, 16 states in the USA (Arizona, California, Colorado, Idaho, Iowa, Minnesota, Montana, Nevada, New York, North Carolina, Oregon, South Dakota, Utah, Washington, Wisconsin and Wyoming) and two provinces in Canada (Ontario and Quebec) were visited. In total, seven wild and weedy Lactuca spp. (L. serriola, L. saligna, L. virosa, L. canadensis, L. biennis, L. floridana, and L. ludoviciana), an interspecific hybrid (L. canadensis × L. ludoviciana), and an undetermined Lactuca species were observed and collected in 200 locations. In this paper, we present new data on the distribution and ecobiology of Lactuca naturally occurring in North America. Morphological assessment of L. serriola samples acquired from North America revealed considerable intraspecific phenotypic variation. Although L. serriola samples originating from various eco-geographical regions differed significantly in their genetic polymorphisms (based on AFLP markers), little variation was observed in their absolute DNA content.This is a proceeding from Acta Horticulturae 918 (2011): 475, doi: 10.17660/ActaHortic.2011.918.59.</p

    The authors compare mathematics curricula at VŠB - Technical University of Ostrava in the year 1979 and at present. They compare the extents and the contents of the curriculum, numbers of lessons and above all the preparedness of students for applications in engineering practice. Reality is compared with the requirements of the European Society for Engineering Education (SEFI) in the material A Framework for Mathematics Curricula in Engineering Education.Autoři srovnávají osnovy předmětu matematika na VŠB TU Ostrava v roce 1979 a v době současné. Porovnávají rozsah a obsah učiva, hodinové dotace a hlavně připravenost posluchačů pro aplikace v technické praxi. Skutečnost je srovnávána s požadavky Evropské společnosti pro inženýrské vzdělávání v materiálu Základní curriculum z matematiky pro evropského inženýra

    Get PDF
    Contains fulltext : 73500.pdf (publisher's version ) (Open Access)This article draws on Czech teachers' ideas about multicultural education at a time when the teaching of multicultural education has become obligatory for primary and secondary schools. After describing the broader context within which this reform has taken place - specifically, the transformation of the educational system and the changing ethnic mosaic of the Czech Republic - the authors present results of a qualitative research study of Czech teachers' ideas about multicultural education
