Hyperaccumulators plants
Web9 mrt. 2024 · Many hyperaccumulators have been described as shallow-rooted (<0.5 m width) and with a high proportion of fine roots for the accumulation of elements [5,10], but deep-rooted herbaceous species (2 m width) exist [11] and the roots of many arboreal hyperaccumulator species have not yet been examined [2]. WebA high accumulation of metals within plant tissue without a strong negative impact on growth, development, or reproduction is called hyper- accumulation. Understanding uptake, transfer,and storage of metals in hyperaccumulators lies at the interface between geochemistry and plant physiology(Wang et al. 2003).

Metal toxicity is tolerated by plant species that are native to metalliferous soils. Exclusion, in which plants resist undue metal uptake and transport, and absorption and sequestration, in which plants pick up vast quantities of metal and pass it to the shoot, where it is accumulated, are the two basic methods for metal tolerance.
