abstract evaluation of pomological characteristics can be useful in selection of best cultivars for commercial purposes. during this project, seven cultivars of sweet cherry including five cultivars from hungary (‘stella’, ‘sunburst’, ‘germesdorf’, ‘summit’ and ‘subima’) and two control cultivars (‘cillage blamarka’ and ‘siahmashad’) were studied by completely rondomized blocks design with thre...

Switching of symbiotic partners pervades most mutualisms, despite mechanisms that appear to enforce partner fidelity. To investigate the interplay of forces binding and dissolving mutualistic pairings, we investigated partner fidelity at the population level in the attine ant-fungal cultivar mutualism. The ants and their cultivars exhibit both broad-scale co-evolution, as well as cultivar switc...

Wheat is a major component within human consumption, and due to the large intake of wheat, it has an impact on human nutritional health. This study aimed at an increased understanding of how the content and composition of tocols may be governed for increased nutritional benefit of wheat consumption. Therefore, ten South African wheat cultivars from three locations were fractionated into white a...

Temperature sweep gel electrophoresis in combination with random amplified polymorphic DNA analysis was employed to detect two markers for a single gene governing low cadmium uptake in western Canadian durum wheat (Triticum turgidum L. var. durum). Analysis of progeny derived from a cross of the high cadmium accumulating cultivar Kyle by the low cadmium accumulating cultivar Nile resulted in li...

Phenotyping local crop cultivars is becoming more and more important, as they are an important genetic source for breeding - especially in regard to inherent root system architectures. Machine learning algorithms are promising tools to assist in the analysis of complex data sets; novel approaches are need to apply them on root phenotyping data of mature plants. A greenhouse experiment was condu...

Soybean is a valuable commodity due to its high oil and protein content and its nutritional and functional food value. Changes in soybean seed composition by environmental stressors including heat and drought have been documented, but the effects of flooding are not yet known. This study profiles the change in seed composition of five soybean plant introductions (PIs) tolerant to flooding stres...

Changes in the biosynthesis of individual carotenoid pigments have been investigated during fruit ripening of five cultivars of red pepper (Capsicum annuum L.): Mana, Numex, Belrubi, Delfin, and Negral (a chlorophyll-retaining mutant when ripe). The study was carried out throughout the ripening process, and with special emphasis on the ripe stage, to discover possible differences between cultiv...

The time to develop new cultivars and introduce them into cultivation is an issue of major importance in plant breeding. This is because plant breeders have an urgent need to help provide solutions to feed a growing world population, while in parallel, time savings are linked to profitability. Plant breeding processes may in general be broken down into the following five key elements: (1) germp...

A century of research on fungus-growing ants (Attini, Formicidae) has ignored the cultivated fungi as passive domesticates and viewed the attine fungicultural symbiosis as an integrated unit dominated by the evolutionary interests of the ant farmers. This article takes a different perspective and explores first the evolutionary interests and leverages of the fungal cultivars, then dissects eigh...

Kováčová M., Malinová E. (2007): Ferulic and coumaric acids, total phenolic compounds and their correlation in selected oat genotypes. Czech j. Food Sci., 25: 325–332. Ferulic and coumaric acids were determined by high-performance liquid chromatography in 21 oat genotypes supplied from the gene bank of the Research Institute of Plant Production in Piešťany (Slovak Republic) with the aim of sele...
