    Notes: To identify markers for the everbearing gene in strawberries, 199 F1 progeny plants were produced from a cross between ‘Ever Berry’ (a Japanese everbearing strawberry) and ‘Toyonoka’ (a Japanese Junebearing strawberry) as the experimental population. The results of flowering tests produced 97 everbears and 102 Junebears. The chi-square test gave a goodness of fit for the expected ratio of 1 : 1 for everbears to Junebears, suggesting the inheritance of the everbearing trait is controlled by a monogenic dominant gene. RAPD analyses on this trait were carried out using ‘Ever Berry’ and ‘Toyonoka’. Seventy-one primers, which produced 89 polymorphic fragments between the two parents, were identified from a total of 175 primers. Five markers relating to the everbearing trait were selected from 26 of the 199 progeny plants. The remaining 173 seedlings were analysed with these five markers and a linkage map was constructed using all of the 199 F1 progeny plants. The length of this linkage group is 39.7 cM. The closest markers found, OPE07-1 and OPB05-1, are respectively mapped at 11.8 and 15.8 cM on each side of the everbearing gene.

    Notes: [Auszug] The structure of the rotor is shown schematically in Fig. 1; it has an axis of rotation on which rests a float and three transverse bars to which blades (or vanes) are attached with wax. The axis and transverse bars are made of glass capillaries. The blades at each end of the transverse bars ...

    Notes: Micro axis-symmetric aspherical glass lenses are being increasingly used in digital devices and optical devices. The glass lenses are molded by using micro ceramic dies such as tungsten carbide [1].Recently, as the pixel number of digital image sensors increases, the accuracy of micro molding dies are required to be much more precise than ever [2]. In this study, ultrasonic assisted polishing method is proposed and developed in order to finish micro axis-symmetric aspherical dies which were pre-ground with a diamond wheel [3]. In this paper, the proposed polishing method was applied to the micro aspherical molding dies to finish form compensation processing

    Nodulation of soybean byRhizobium japonicum mutants with altered capsule synthesis (1982)

    Notes: Abstract Spontaneous mutants with altered capsule synthesis were isolated from a marked strain of the symbiont,Rhizobium japonicum. Differential centrifugation was used to enrich serially for mutants incapable of forming capsules. The desired mutants were detected by altered colony morphology and altered ability to bind host plant lectin. Three mutants failed to form detectable capsules at any growth phase when cultured in vitro or in association with the host (soybean,Glycine max (L.) Merr.) roots. These mutants were all capable of nodulating and attaching to soybean roots, indicating that the presence of a capsule physically surrounding the bacterium is not required for attachment or for infection and nodulation. Nodulation by several of the mutants was linearly proportional to the amount of acidic exopolysaccharide that they released into the culture medium during the exponential growth phase, indicating that such polysaccharide synthesis is important and perhaps required for nodulation. Two of the mutants appeared to synthesize normal lectin-binding capsules when cultured in association with host roots, but not when cultured in vitro. Nodulation by these mutants appeared to depend on how rapidly after inoculation they synthesized capsular polysaccharide.

    Notes: Summary A high pigment-producing strain of cultured Euphorbia millii cells was isolated by clonal selection. The pigment obtained was red and consisted mainly of anthocyanin. The amount of this pigment obtained after 24 selections was seven times that found in the original cells. Statistical and cell-pedigree analyses proved that this cell strain has stable productivity for this red pigment.

    Description / Table of Contents: Summary The pulse-polarographic behaviour of tributyltin chloride (TBTC) and dibutyltin dichloride (DBTC) in ethanol-water mixtures has been studied. The effects of temperature, pH, modulation amplitude, solvent and supporting electrolyte compositions were investigated. The reduction processes are complicated and pH-dependent. DBTC gave one reversible reduction wave and TBTC showed a quasi-reversible one and also several irreversible waves. Both the organotin compounds in the concentration of 10−7 mol/l were determined by differential pulse polarography. The method was successfully applied to the analysis of commercially available fishing nets. Detection limits were 2.2×10−7 and 6.2×10−8 mol/l for TBTC and DBTC, respectively.
    Notes: Zusammenfassung Das puls-polarographische Verhalten von Tributylzinnchlorid (TBTC) und Dibutylzinndichlorid (DBTC) in Ethanol-Wasser-Gemischen wurde untersucht und die Wirkung von Temperatur, pH, Modulationsamplitude sowie Zusammensetzung des Lösungsmittels und Leitelektrolyts geprüft. Die Reduktionsprozesse waren kompliziert und abhÄngig vom pH. DBTC ergab eine reversible Reduktionswelle, TBTC eine quasireversible Welle, sowie daneben einige irreversible Wellen. Beide Organozinnverbindungen konnten in einer Konzentration von 10−7 mol/l durch Differential-Puls-Polarographie bestimmt werden. Die Methode wurde erfolgreich auf die Analyse von handelsüblichen Fischernetzen angewandt. Die Nachweisgrenzen lagen bei 2,2·10−7 (TBTC) bzw. 6,2 · 10−8 mol/l (DBTC).
