    Notes: [Auszug] Ability of a number of different nitrogenous materials, and amino-acids when individually used as the sole source of nitrogen and of various sugars and carbohydrates to produce pigment in Sabourauds medium, have been determined. The extent of pigmentation observed after 8 days is given in ...

    On the luminescence of TlCl+KCl phosphor (1962)
    Springer
    The European physical journal 167 (1962), S. 20-25 
    Details
    ISSN: 1434-601X

    Notes: Abstract The measurements on the luminescence spectra of TlCl+KCl mixed phosphor under low energy cathode rays at 80° K have been presented here. The reflectance as well as excitation spectra of this mixed phosphors have also been studied. The X-ray diffraction studies of the samples along with the optical studies show that the mixed phosphor consists of two phases: (1) KCl:Tl (2) TlCl:K. It has been observed that the emission bands due to thallous chloride are gradually quenched with the increase in potassium chloride content of the phosphor; further, the emission bands supposed to be due to KCl:Tl phosphors gradually appear. Since some of the emission bands obtained with KCl:Tl phosphors at high thallium content are also present in the luminescence spectra of thallous chloride it is suggested that such bands should be attributed to undissociated thallous chloride present in KCl:Tl phosphor. The quenching of thallous chloride emission by the incorporation of potassium chloride in the system has been explained as being due to the absence of stoichiometric excess of thallium in such mixed system. The results also show that the absorption spectra of the mixed system is determined by the minor components KCl:Tl. This indicates that the absorption spectra of KCl:Tl phosphor should not be affected by the presence of undissociated thallous chloride.

    Interspecific hybridization between Corchorus sidoides F. Muell. and C. siliquosus L., a natural polyploid (1961)
    Springer
    Euphytica 10 (1961), S. 113-119 
    Details
    ISSN: 1573-5060
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Abstract In Corchorus sidoides F. Muell ♀ x C. siliquosus L. ♂, the pod set was 19.05 per cent. and the percentage of pod harvested (out of set pods) was 100 per cent.. All seeds of the cross pods were non-viable. In C. siliquosus L. ♀ x C. sidoides F. Muell. ♂, the pod set was 8.7 per cent. and the percentage of pod harvested was 100. In this case the seeds were also non-viable. The genus Corchorus comprises species which are systematically widely related. The possibility of getting viable hybrids in this case is impossible because the phylogenetic relationship does not allow of getting viable seeds. A karyotypic study of these species will throw light on this aspect and breeders will then get a tool for handling this subject.

    Study on the rate of pollen tube growth ofSesbania aculeata Pers. Under infra-red radiation in culture medium (1960)
    Springer
    Plant systematics and evolution 107 (1960), S. 80-83 
    Details

    Topics: Biology
    Notes: Summary The rate of pollen tube growth per hour ofSesbania aculeata Pers. under the infra-red rays was slower than the rate of pollen tube growth per hour under day light. When the infra-red rays were offered in combination with normal light or vice versa, in no case the rate of pollen tube growth per hour surpassed the normal rate of pollen tube growth per hour, under day light during the 4 hours' phase of growth.
