This paper presents the results from a study of consumer reactions to different attributes of red and white wine, with stimuli presented in the form of small, experimentally designed, test concepts (conjoint measurement). The results show that possibly four consumer mind-sets exist, with each mind-set comprising a different set of communication drivers for concept acceptance. Most subjects fit into one of three key categories; "Classics" (who want their wines to be traditional), "Imaginers" (who want to get into the drinking experience through knowing details about their wines) or "Elaborates" (who want their wines to produce many sensations and flavors). A fourth group (No Frills), were interested in simple and safe wines without any detail of flavor or origin. This segment was found in the red wine study, but not in the white wine study. 相似文献

Chromosome numbers of taxa of Festuca L. section Eskia Willk. in the Iberian Peninsula are given. The levels of ploidy for five taxa are confirmed. Idiograms and karyotypic formulae of the five taxa are presented for the first time. Two levels of ploidy occur in this section: diploid and tetraploid. One taxon, Festuca elegans ssp. merinoi is tetraploid and two other taxa have diploid and tetraploid populations. The remaining two taxa are solely diploid. © 2004 The Linnean Society of London, Botanical Journal of the Linnean Society , 2004, 146 , 331–337. 相似文献

The differences in K+ uptake of different segments of excised roots of two thermophilic plants (rice, Oryza sativa L. cv. Dunghan Shali and cucumber, Cucumis sativus L. cv. Csemege Fürtös) and a non-thermophilic plant (wheat, Triticum aestivum L. cv. Aurora) were investigated in the presence and absence of Ca2+, at 0 and 25°C, using radiotracer K+(86Rb+) technique. The K+ uptake exhibited different temperature- and Ca2+-dependent distributions along the root axis for the different species studied. In the case of rice and cucumber an extraordinarily large K+ uptake occurred in the apical root portion at 0°C if Ca2+ was omitted. The presence of Ca2+ diminished this anomaly. For wheat normal K+ uptake patterns were observed under similar conditions. At 25°C Ca2+-stimulated K+ uptake may appear in each root segment, depending upon species and composition of the uptake solution. The results indicate that there may be considerable differences in the compositions of the cell walls and membranes of root cells of thermophilic and non-thermophilic plants, and in their ion-exchange properties, especially in the apical region. 相似文献

The effects of Ca2+ and temperature on the K+ contents of root segments of wheat (Triticum aestivum L. cv. Aurora), rice (Oryza sativa L. cv. Dunghan Shali) and cucumber (Cucumis sativus L. cv. Csemege Fürtös) were investigated with special regard to the low-temperature anomaly of the K+ uptake of thermophilic plants. The anomaly occurred in those root segments where the K+ contents turned out to be highest. The K+ contents of the apical root sections of thermophilic species responded in general to Ca2+ in more pronounced ways than those of wheat, at both 0 and 25°C. The concerted actions of a purely physical process with negative temperature coefficient and of the special thermotropic properties of the membranes are suggested to be responsible for the low-temperature anomaly. A strict discrimination between the Viets-effect on the content (classical Viets-effect) and on the uptake is proposed. The classical Viets-effect seems to be related to alterations in both active transport and exchange processes. 相似文献
