  • use and abuse of trace metal concentrations in Plant Tissue for biomonitoring and phytoextraction
    Environmental Pollution, 2005
    Co-Authors: Jan Mertens, Sebastiaan Luyssaert, Kris Verheyen
    Abstract:

    Some Plant species accumulate trace metals from the soil in their aboveground biomass. Therefore, some scientists have concluded that these species are suitable for biomonitoring trace metal concentrations in the soil or for removing excessive trace metals from the soil by means of phytoextraction. A significant correlation between the chemical composition of foliage and soil is not a sufficient condition for using the chemical composition of foliage as a biomonitor for the quality of the soil. The chemical composition of foliage can, however, provide additional information to the traditional soil samples. The phytoextraction potential of a Plant species cannot solely be evaluated on the basis of the trace metal concentrations in the Plant and soil Tissue. Data on the depth of the rooting zone, the density of the soil and the harvestable biomass should also be taken into account. Although Plant Tissue analysis is a useful tool in a wide range of studies and applications, trace metal concentrations in Plant Tissue cannot be viewed in isolation. Instead it should be analysed and interpreted in relation to other information such as soil concentrations, rooted zone, biomass production, etc.

  • thidiazuron a potent cytokinin for woody Plant Tissue culture
    Plant Cell Tissue and Organ Culture, 1993
    Co-Authors: Carl A. Huetteman, John E. Preece
    Abstract:

    Thidizuron (TDZ) is among the most active cytokinin-like substances for woody Plant Tissue culture. It facilitates efficient micropropagation of many recalcitrant woody species. Low concentrations (<1 µM) can induce greater axillary proliferation than many other cytokinins; however, TDZ may inhibit shoot elongation. In some cases it is necessary to transfer shoots to an elongation medium containing a lower level of TDZ and/or a less active cytokinin. At concentrations higher than 1 µM, TDZ can stimulate the formation of callus, adventitious shoots or somatic embryos. Subsequent rooting of microshoots may be unaffected or slightly inhibited by prior exposure to TDZ. The main undesirable side effect of TDZ is that cultures of some species occasionally form fasciated shoots. The high cytokinin activity and positive response of woody species to TDZ have established it as among the most active cytokinins forin vitro manipulation of many woody species.
