    Nature of Vestured Pits in Angiosperms (1963)
    [s.l.] : Nature Publishing Group
    Nature 197 (1963), S. 202-203 
    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] Sections cut after maceration with hdryogen peroxide acetic acid showed that this treatment removed the lining membrane, but the enclosed outgrowth of the cell wall forming the vesture was attacked at apparently the same rate as the cell wall itself. The lining membrane (Figs. 1 and 2) was strongly ...

    Occurrence of Peroxidase in Tension Wood of Angiosperms (1956)

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] In investigations into the nature of lignification, the work of Freudenberg et al.2,3, and of Siegel4 has shown that the mechanism most probably involves oxidation of a phenyl propane type precursor by an oxidase, phenoloxidase or peroxidase. In conifers the seasonal variation in peroxidase in the ...

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] Parts of an enveloping parent wall, apparently persisting after division in the ray initials, were observed connecting adjacent cells of a radial file of ray parenchyma cells isolated by simple maceration (Fig. 1). An example, which may perhaps be more important, was observed in the course of a ...

    Helical Thickenings and Micellar Orientation in the Secondary Wall of Conifer Tracheids (1951)

    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] In conifer tracheids the normal secondary cell wall consists of three layers of different helical micellar orientation such that in the outer and inner layers the micelles make a large angle ('micellar angle') with the longitudinal cell axis, whereas in the middle layer this angle is small9'10. A ...

    Wart Structure of Gymnosperm Tracheids (1962)

    Notes: [Auszug] In Actinostrobus pyramidalis the wart structure is large and readily seen in an optical microscope. Wardrop, Liese and Davies5 concluded that the isolated structure consisted of a non-cellulosic membrane which formed a lining of the cell lumen and was extended in a series of diverticula protruding ...

    Notes: [Auszug] These observations are of interest in providing evidence of the origin of phenolic substances within the cell and the manner of their deposition in the vacuoles. They imply some relation, not necessarily direct, between the dissolution of reserve starch and processes leading to the formation of ...

    Notes: [Auszug] THE increasing preoccupation of plant physiological laboratories throughout the world with problems of growth makes it very desirable that the details of structure in the cell wall, in growing tissue, should be known as completely as possible in the condition occurring in the living tissue ...

    An Electron-Microscopic Investigation of the Cell-wall Organisation of Conifer Tracheids (1950)

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] To obtain direct evidence using the electron microscope, in support of the above conception of cell-wall organisation in conifer tracheids, it is sufficient that the micellar orientation in either the outer or inner layer should be established, since the existence of a steep micellar spiral in the ...

    Notes: [Auszug] IN recent X-ray investigations1 upon the cell wall organisation of conifer cambium, it was observed that much of the diffuse radiation tending to mask the diffraction diagram of the cellulose could be eliminated by a preliminary extraction of the tissue with pectic solvents or ...
