“…When the quantities of metal ions are higher than the adsorption capacity of the plaque, it is not able to inhibit metal ion uptake and trans-location effectively. That Typha plants often take up more metal from metal solutions than plants from the field has been shown by Taylor & Crowder (1983 c) and Ye et al (1997). Metal precipitation on plaque might differ under hydroponic and natural conditions.…”

“…Earlier studies showed that this population has not evolved to a metal-tolerant ecotype (Ye et al, 1997). The seeds were germinated at 22 °C, and seedlings were grown for 20 wk in 10 % (v/v) Rorison solution (Hewitt, 1966), and for the first 9 wk supported in Alkathene® beads.…”

“…Typha latifolia L. is a common and productive wetland plant of world-wide geographical distribution. It can colonize metal-contaminated areas (McNaughton et al, 1974;Taylor & Crowder, 1983a;Ye et al, 1997) and produce iron plaque under field and in culture solution conditions (Taylor et al, 1984;Crowder et al, 1987;Ye, Baker & Wong, 1994). The experiments presented here aimed to determine the effect of iron plaque on growth and copper (Cu) and nickel (Ni) immobilization, accumulation and tolerance in T. latifolia.…”

SUMMARYThe effects of iron plaque on the growth of Typha latifolia L. and accumulation of copper and nickel in T. latifolia were investigated under laboratory conditions in nutrient solution cultures. Seedlings with and without iron plaque on their roots were exposed to 0-05 //^g ml"^ Cu and 010 //g m\~^ Ni solutions for 72 d. The results showed no differences in root and shoot d. wt and leaf elongation when Cu or Ni were added to the solution and in the presence or absence of plaque. However, root length was reduced by Cu and Ni, and the reduction in root length was greater in the presence of plaque. Some Cu and Ni was adsorbed on root surfaces; roots with plaque took up more Cu, but less Ni than those without. The presence of plaque did not alter Cu uptake and translocation but increased Ni uptake and translocation. Most of the Cu and Ni taken up was retained in the roots, suggesting that the root tissue rather than the root surface or plaque is the main barrier for Cu and Ni transport. The results differ from those reported for other species.

“…There is now evidence that constitutive metal tolerance exists in some species. McNaughton et al (1974), Taylor & Crowder (1984) and Ye et al (1997) compared Typha latifolia populations from uncontaminated and contaminated sites and found that, whatever the origin of the population, there is no difference in tolerance. The authors concluded that the species exhibited a constitutive tolerance to Zn, Pb and Cd throughout its range.…”

Zinc tolerance and accumulation in metallicolous and nonmetallicolous populations of Arabidopsis halleri (Brassicaceae)

et al. 2000

Zinc tolerance was investigated in five populations of Arabidopsis halleri (syn. : Cardaminopsis halleri) raised from seeds collected from contaminated and uncontaminated sites. Tolerance was measured by determining the concentration which inhibited root growth (EC "!! ). A. halleri populations from contaminated and uncontaminated sites were found to be Zn-tolerant compared with the Zn-nontolerant species Arabidopsis thaliana and A. lyrata subsp. petraea. At very high Zn concentrations, populations of A. halleri from uncontaminated sites were slightly less Zn-tolerant than those from contaminated sites. These observations support the hypothesis that in A. halleri, Zn tolerance is largely a constitutive property. One population from an uncontaminated site and one population from a contaminated site were studied for Zn uptake. Zinc content was measured in shoots and roots using a colorimetric test under laboratory conditions. The results showed that whatever their origin, individuals from both populations are Zn accumulators compared with the nonaccumulator species A. thaliana. Moreover, the population from the uncontaminated area accumulated Zn in its shoots and roots more quickly than the population from the contaminated site. These results suggest that, in A. halleri, Zn accumulation to very high concentration is a constitutive property.

“…Lead-tolerant plants tend to be root accumulators showing restricted Pb translocation from root to shoot (Baker and Walker 1990;Shu et al 2012). Previous studies have suggested that some wetland plant species accumulate very low Pb concentrations in their shoots even when grown in highly Pb contaminated substrates (Ye et al 1997a(Ye et al , b, 2001Deng et al 2004Deng et al , 2006 and employing an 'excluder' strategy (sensu Baker 1981). Other species, however, accumulate higher Pb concentrations in their shoot tissues without any visible toxicity symptoms.…”

Constructed wetlands used to clean up toxic metals such as lead (Pb) from contaminated wastewater are considered as an effective and low-cost technology. The effect of Pb on the biomass, tolerance, soluble protein, and antioxidant enzymes in 18 candidate wetland plant species grown in soils without (control) and spiked with 900 and 1800 mg Pb kgwas studied in a pot trial. Our pot experiment showed that the biomass, tolerance, and leaf protein contents decreased with increasing concentrations of Pb in soil. There were significant differences between the plants in their Pb tolerance indices (29-82 % in the 900 mg Pb kg −1 amended soil) and also Pb uptake (13-749 mg kg −1 in shoots and 1112-4891 mg kg −1 in roots, in the same treatments). Activities of superoxide dismutase (SOD) and peroxidase (POD) in leaves of most of the plants increased with increasing level of soil Pb concentration. Conversely, catalase (CAT) activity in leaves declined when plants were subjected to Pb stress. Lead accumulation by the 18 wetland plant species screened was strongly dependent on the species and Pb concentrations in the soil. However, Pb translocation from root to shoot was generally low in all species. Increases in SOD and POD activities suggest that the antioxidant system may play an important role in alleviating Pb toxicity in wetland plants. The data obtained should help in future species selection for the use in designing wetlands in Pb-contaminated environments.
