    Genetics of disease resistance in urdbean (Vigna mungo (L.) Hepper) to the leaf spots caused by Colletotrichum truncatum (Schw.) Andrus & Moore (1988)

    Euphytica 37 (1988), S. 279-281

    ISSN: 1573-5060
    Keywords: Vigna mungo ; urdbean ; Colletotrichum truncatum ; leaf spotting ; inheritance of resistance ; non-allelic

    Notes: Summary The resistance sources among various test cultivars of urdbean to Colletotrichum truncatum, a leaf spotting pathogen, were identified and genetics of resistance was worked out by studying F1, F2 and F3 generations of crosses between resistant cultivars and the susceptible cv. Kulu 4 and of those among the resistant parents. The resistance was found to be controlled by single dominant genes and the resistance genes were non-allelic.

    Description / Table of Contents: Die Kinetik der Polymerisation von Acrylnitril in wäßriger Lösung mit Peroxodi-sulfat-Thioharnstoff als Redoxinitiator wurde im Temperaturbereich von 40-50°C erforscht. Der Einfluß der Konzentration von Thioharnstoff, Monomeren und Peroxodisulfat auf die Polymerisationsgeschwindigkeit als such auf den Umsatz wurde untersucht. Auch die Auswirkungen einiger anorganischer Salze und verschiedener oraganischer Lösungsmittel auf die Polymerisationsgeschwindigkeit wurde studiert. Die Untersuchung des isolierten Polymeren erfolgte mittels IR-Spektroskopie. Ein ge-eignetes kinetisches Schema wurde vorgeschlagen und ein pasender Geschwindig-keitsaudruck abgeleitet.
    Notes: An investigation on kinetics of aqueous polymerization of acrylonitrile (AN) initiated by peroxodisulfate-thiourea redox system has been carried out in the temperature range of 40° to 50°C. The concentration effect of thiourea, monomer, peroxodisulfate on polymerization rate and percentage of conversion has been studied. The effect of some inorganic salts and different organic solvents on polymerization rate has also been investigated. The isolated polymer has been characterized by IR spectra. A suitable kinetic scheme has been proposed and appropriate rate expressions have been derived and explained in the light of experimental findings.

    Graft copolymerization of acrylonitrile onto acetylated jute fibers (1989)

    Notes: Graft copolymerization of acrylonitrile (AN) onto acetylated chemically modified jute was carried out in the temperature range 40-60°C using V5+-cyclohexanone redox initiator system. The effects of temperature, time, concentrations of metal ion (V5+), monomer (AN), cyclohexanone, some inorganic salts, and organic solvents on percent grafting have been studied. IR spectra of acetylated chemically modified jute and grafted jute have been taken, and their characteristic bands have been identified. Grafting has improved the thermal stability and also the lightfastness rating of jute fibers dyed with basic dyes.

    Notes: Graft copolymerization of acrylonitrile (AN) onto chemically modified bleached jute fibers was studied using Ce(IV)-hippuric acid redox initiator system. The effects of time, temperature, concentration of monomer (AN), metal ion (Ce4+), hippuric acid, sulfuric acid, and amount of jute fiber on graft yield have been studied. The effects of some organic solvents and inorganic salts on graft yield have also been studied. Infrared spectra of chemically modified bleached jute and grafted jute have been taken and their characteristic bands have been identified. More than 90% graft yield could be achieved with the present system.
