“…The greenhouse experiment procedure was conducted according to a study by Sołtysiak and Brej (2019), where the effect of different doses of Pb on invasive Fallopia x bohemica (a hybrid of F. japonica and F. sachalinensis) was examined. The prepared plant materials (rhizome fragments of F. japonica) were introduced into plastic pots (one rhizome in each pot) with a capacity of 5 kg of soil.…”

In order to assess the tolerance of the highly invasive weed Fallopia japonica to heavy metals, a greenhouse experiment was conducted in which this plant was cultivated in control soil and in the soils polluted by different levels of Cd, Cr, Cu, Pb and Zn. The content of heavy metals in soil did not eliminate the F. japonica rhizome's capacity to regenerate. However, at the beginning of the experiment, the presence of some metal doses: Cd (100, 200 mg•kg-1), Pb (200 mg•kg-1) and Zn (300 mg•kg-1) delayed the rhizome regeneration compared to the control plants. In the soils contaminated with any level of Cr or Pb, shoots grew with similar vigour to the control plants. Only the high doses of Cd (100, 200 mg•kg-1), Cu (300 mg•kg-1) and Zn (300 mg•kg-1) significantly delayed the plants' growth. The morphological features of F. japonica from the soils polluted with Cr and Pb were not significantly different from the control plants. Among the tested heavy metals that had the greatest impact on the morphology of F. japonica were Cd (100, 200 mg•kg-1), Cu (300 mg•kg-1) and Zn (300 mg•kg-1). A chemical analysis indicated that this weed accumulated large quantities of metals when cultivated in the contaminated soil. Particular attention was paid to its relatively high Cd uptake. In the variant where a dose of 100 mg Cd•kg-1 was applied, the plants (aboveground part) accumulated more than 630 times the amount of cadmium found in the control. The abilities of F. japonica to regenerate from rhizome fragments, to grow and develop under the stress conditions created by heavy metals, and to take up metals are evidence that this plant is characterised by metal tolerance.

“…In some cases, plant morphology is not affected by the presence of higher levels of heavy metals. For example, there was no negative effect of even a high dose of Pb found on the morphological characteristics of a Fallopia x bohemica hybrid [66]. Moreover, plant height in Japanese Knotweed s.l.…”

Invasive plant species possess remarkable abilities to establish themselves in new environments and to displace native species. Their success can be attributed to various physiological and biochemical mechanisms, allowing them to tolerate adverse environmental conditions, including high lead (Pb) toxicity. Comprehension of the mechanisms responsible for Pb tolerance in invasive plants is still limited, but it is rapidly evolving. Researchers have identified several strategies in invasive plants to tolerate high levels of Pb. This review provides an overview of the current understanding of the ability of invasive species to tolerate or even accumulate Pb in plant tissues, including vacuoles and cell walls, as well as how rhizosphere biota (bacteria and mycorrhizal fungi) help them to enhance Pb tolerance in polluted soils. Furthermore, the article highlights the physiological and molecular mechanisms regulating plant responses to Pb stress. The potential applications of these mechanisms in developing strategies for remediating Pb-contaminated soils are also discussed. Specifically, this review article provides a comprehensive understanding of the current status of research on the mechanisms involved in Pb tolerance in invasive plants. The information presented in this article may be useful in developing effective strategies for managing Pb-contaminated soils, as well as for developing more resilient crops in the face of environmental stressors.

Recently, plant remediation techniques -phytoremediation -have been developed. Japanese Knotweed (Reynoutria japonica), is an invasive species with negative impacts on the environment and the economy. In order to assess the tolerance of highly invasive weeds to heavy metals, an experiment was conducted in which this plant was grown in control soil and in soils contaminated with different concentrations of Pb, Cd. The content of heavy metals in the soil did not eliminate the ability of Reynoutria japonica roots to regenerate. In soil contaminated with any concentration of Pb, the shoots of this plant grew at a similar rate as the control plants, and had the same morphological characteristics. Higher concentrations of cadmium and lead Cd (100, 200 mg kg -1 ), Pb (2000 mg kg -1 ) have extended rhizome regeneration compared to control plants. In soils contaminated with lower concentrations of Cd or Pb shoots grew at a similar rate as control plants. Chemical analysis of heavy metal content showed that this weed accumulated large amounts of metals when grown in soil contaminated with heavy metals A relatively high intake of Cd, aboveground plants. At a cadmium concentration of 100 mg kg -1 , more than 537 times the amount of cadmium accumulated in the aboveground part of the plant, as opposed to that in control. The ability of Japanese Knotweed (Reynoutria japonica), to regenerate from parts of the rhizome, to grow and develop under stressful conditions in the presence of heavy metals indicates a high tolerance to heavy metals.
