The extent and applications of metal accumulation and hyperaccumulation in Philippine plants
To examine the potential applications of hyperaccumulator plants in the Philippines, we reviewed current data on the extent of metal hyperaccumulation in native species and partitioning of metals within the plant tissue. Twenty-eight species had reported tissue concentrations above the hyperaccumulator threshold, 11 species were endemic to the Philippines. Nickel was present in higher concentrations in the aboveground tissue than in the belowground tissue, but the reverse was found for copper, aluminium and chromium. The fact that copper accumulates belowground rather than above, and most hyperaccumulators of nickel identified were trees, has implications for the potential of phytoextraction using native Philippines flora.
期刊介绍:
Australian Journal of Botany is an international journal for publication of original research in plant science. We seek papers of broad interest with relevance to Southern Hemisphere ecosystems. Our scope encompasses all approaches to understanding plant biology.
Australian Journal of Botany is published with the endorsement of the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Australian Academy of Science.
