    Palm “Wood” I. Anatomical aspects (1976)

    Notes: Abstract The “wood” of palms consists of primary vascular bundles imbedded in a parenchymatous ground tissue. The texture and hardness of a palm stem or petiole depend largely upon the distribution of vascular bundles and the amount of sclerenchyma present. The sieve elements are structurally similar to those in other angiosperms. However, in palms the sieve elements are long-lived, unlike those in most dicotyledons and gymnosperms. Metaxylem tracheary elements vary in their morphology depending on the organ and/or species in which they occur. Scanning electron microscopy observations indicate that the distinction between tracheids and vessels is not sharp but is a matter of degree. The fibers usually have a well developed secondary wall with a characteristically mulilayered appearance. There are indications that the protoplast of these cells continues to lay down secondary walls over a long period. Fibers are commonly associated with silica-containing cells, the stegmata.

    Soil carbon dioxide and mineral accumulation in citrus seedlings (Citrus sinensis var. Bessie) (1971)
    Springer
    Plant and soil 35 (1971), S. 337-346 
    Details
    ISSN: 1573-5036
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary This experiment was conducted in a greenhouse to study the influence of soil CO2 differential treatments on plant response, concentrations of nutrients in soils and plants, and total nutrients per plant (Citrus sinensis var. Bessie). Higher levels of soil CO2, applied to the roots, significantly increased the amount of dry weight per seedling, the height of seedling, and decreased the concentrations of N, P, Ca, Mg, and Mn in the tops. The dry weight of roots supplied with high soil CO2 was decreased, while the concentrations of Mg and Mn were increased. Concentrations of N, P, K, and B in the roots were also reduced due to high level of soil CO2. Only total K and Mg per plant were increased with an increased soil CO2 supply. No significant interactions were found between the soil CO2 treatments and years of experiment.

    Dependence of polynucleotide helix-coil transition theory on the ring closure exponent (1969)
    New York : Wiley-Blackwell
    Biopolymers 7 (1969), S. 265-273 
    Details
    ISSN: 0006-3525
    Keywords: Chemistry ; Polymer and Materials Science
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: Formulas are derived which relate the maximum slope of the helix-coil transition in synthetic polynucleotides to the stacking free energy and to the exponent k in the expression for the probability of ring closure for polymer chains. The exact value of k has not yet been determined. By use of the derived formulas, it is then shown that estimates of the stacking free energy are sensitive enough to the value chosen for k, so that exact values of these energies must await a precise determination of k.
