    Notes: Abstract  We have isolated and characterised microsatellite loci from Pelargonium sp. to explore the potential of these markers for cultivar identification. Small-insert libraries from a zonal (Pelargonium x hortorum cv. Isabell) and an ivy-leaved variety (P. peltatum cv. Guenievre gergue) were enriched for d(AG), d(AC), d(CAA), d(GAA) and d(GATA) repeats. Of 141 positive clones sequenced, 133 contained a microsatellite. Primers for PCR amplification were designed to the flanking regions of 57 microsatellites, resulting in interpretable amplification products of the expected size for 29 loci. Seventeen primer pairs amplifying 18 loci were used to fingerprint 44 di- and tetra-ploid Pelargonium accessions representative of commercially available varieties. Multilocus genotypes obtained at 3 loci distinguished among all accessions, except for three known flower colour sports and a fourth, phenotypically very similar, variety. Allelic composition was also identical within two other sport ’families’ typed at the same 18 loci. UPGMA and principal co-ordinate analysis of pairwise distance matrices derived from PCR amplification patterns revealed four distinct assemblages. The first group consisted of tetraploid P. x hortorum varieties; a second group contained diploid P. x hortorum, a third, tetraploid P. peltatum accessions, while a fourth, very distinct, group consisted solely of diploid P. peltatum varieties. Polymorphism in P. peltatum was equal or greater than in P. x hortorum at 17 of the 18 loci, indicating that the analysed P. peltatum varieties form a genetically more variable array.

    Zum strukturellen Verformungsverhalten einiger Tonmineral-Wasser-Systeme (1970)

    Description / Table of Contents: Summary The deforming behaviour of plastic clay-water-systems was determined by a parallel plate plastometer in retardation and discharging tests considering the kind of mineral, the loading with cations, the surface, and the water content. By different methods of evaluation it was possible to achieve results concerning a critical water content, depending on the material, as well as concerning the binding power. The elastic deformation in connection with the above mentioned results gives knowledge about the structural characteristics.
    Notes: Zusammenfassung Das Verformungsverhalten von plastischen Ton-Wasser-Systemen wurde mittels Parallelplattenplastometer in Retardations- und Entlastungsversuchen bestimmt. Dabei wurden die Mineralart, Kationenbelegung und Oberfläche sowie der Wassergehalt berücksichtigt. Durch verschiedene Auswertungsmethoden konnten Aussagen über einen stoffabhängigen kritischen Wassergehalt und über das Bindevermögen gewonnen werden. Die elastische Deformation in Verbindung mit den obigen Ergebnissen vermittelt Erkenntnisse über die strukturellen Eigenschaften.
