    Influence of sequential prolonged periods of dark and light on pinitol concentration in clover and soybean tissue (1982)
    Oxford, UK : Blackwell Publishing Ltd
    Physiologia plantarum 54 (1982), S. 0

    Notes: The influence of prolonged dark periods on the concentration of pinitol in white clover (Trifolium repens L. ev. Regal Ladino) and soybean [Glycine max (L.) Merr.] tissue was investigated. Clover and soybean plants were harvested periodically throughout continuous dark periods of 40 and 44 h, respectively, followed by 24 h of continuous light. The foliage and root tissue of clover and foliage tissue of soybeans were analyzed for the concentration of glucose, fructose, sucrose and pinitol. Pinitol concentration (mg/g dry weight tissue) was unchanged by the prolonged dark period followed by 24 h of continuous light compared to tissue of plants harvested at 0-h and plants receiving normal photoperiods. Concentrations of the carbohydrates, in the tissue were depleted by the prolonged dark period. However after 6 h of light, the concentration of these sugars increased to concentrations equal to 0-h harvested plant tissue and tissue of plants receiving normal photoperiods. These results indicate that pinitol probably does not function as a source of reserve energy comparable to sucrose, glucose, and fructose.

    Callus and Plantlet Regeneration from Cell Cultures of Ladino Clover and Soybean (1977)
    Oxford, UK : Blackwell Publishing Ltd
    Physiologia plantarum 39 (1977), S. 0

    Notes: The auxin to cytokinin ratios are described for promoting growth in the in vitro cultures of soybean (Glycine max (L.) Merr. cv. Bragg) and perennial clover (Trifolium repens L. cv. Regal Ladinc). Callus growth was induced on somatic tissue with 50:1 auxin to cytokinin (w/w) ratio. A 5:1 ratio served for initiation of cell suspensions from callus and for subsequent growth of callus from cells in suspension. A 1:2 ratio served for regeneration of buds and plantlets from the callus grown from cells. Although (2,4-dichlorophenoxy) acetic acid was the auxin for suspension and regenerative cultures, (2,4,5-trichlorophenoxy)acetic acid was the more effective auxin for initiation of callus on somatic tissue. All cultures were grown with 6-furfurylaminopurine as the cytokinin.The phytohormones strongly influenced the rates of culture growth, but determination of culture type was augmented by dl-alpha tocopherol acetate and iron. Tocopherol and a relatively high complement of iron promoted growth of juvenile cultures, whereas low level of iron and absence of tocopherol favored growth to comparatively more differentiated cultures. Without tocopherol, no callus formed on somatic tissue during the allotted period of incubation. Tocopherol plus a complement of low iron enabled growth of callus on rapidly growing somatic tissue. A high level of iron enabled comparatively more callus growth but suppressed growth of somatic tissue. In suspension cultures tocopherol and a high iron level enhanced dispersion of cells. A low iron complement in the absence of tocopherol induced growth of callus from cells and subsequent regeneration of buds and plantlets from the callus.

    An automatic mesh generation scheme for plane and curved surfaces by ‘isoparametric’ co-ordinates (1971)
    Chichester [u.a.] : Wiley-Blackwell

    Notes: A computer orientated method is presented which generates meshes of triangular elements in plane and curved surfaces. Depending on geometrical and material variations, the region to be discretized is divided into a number of four sided zones. By using curvi-linear co-ordinate systems, nodes within and on the boundary of each zone are automatically positioned and referenced to a global Cartesian co-ordinate system. Elements are automatically assembled from these nodes. Input data is required to specify the positions and material properties of each zone and how they are connected. Examples are given which illustrate the range of meshes that can be generated. Extension of the method to generate three-dimensional tetrahedral elements is indicated.
