摘要

为了研究高积累植物在菲律宾的潜在应用,我们查阅了有关本地物种的金属高积累程度以及金属在植物组织内的分配的现有数据。据报道,有 28 种植物的组织浓度超过了超积累阈值,其中 11 种是菲律宾特有的植物。镍在地上组织中的浓度高于地下组织,但铜、铝和铬的情况正好相反。铜在地下而不是在地上积累,而且已发现的大多数镍的高积累者都是树木,这一事实对利用菲律宾本地植物区系进行植物萃取的潜力产生了影响。

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.
