“…According to the estimated values, there was a reduction between the control treatment (natural soil) and the 300 mg dose of Cu kg -1 of soil after plant growth, with 17% for the stem diameter, 39.7% for the dry matter of the root part and 43.2% for the specific superficial area. Studies with tree species have shown a reduction in the stem diameter and root system due to elevated contents of Cu(II) in the soil (Dellai et al, 2014;Silva et al, 2014). This high soil Cu content inhibits root growth, being one of the most evident symptoms of Cu(II) toxicity, just like what was observed in this study.…”

Phytoremediation is a technique that uses plants, whether associated or not to ameliorating agents, for phytostabilization of contaminated soil. The aim of this study was to evaluate the use of Senna multijuga associated with peat in the phytostabilization of copper contaminated soil. The experiment was carried out in a greenhouse for 120 days, using an entirely randomized design in a factorial arrangement (2 x 6), with and without peat (200 mL L-1 soil) and six doses of copper (0, 60, 120, 180, 240, 300 mg kg-1), with six repetitions of each treatment. At 120 days after seedling, the plants were evaluated for height, stem diameter, root and aerial dry matter, contents and accumulated amount of copper in the root system and aerial part. Also, the Dickson quality indexes, as well as tolerance and translocation indexes were analyzed. The results showed that the use of 200 mL of peat L-1 of soil was inefficient as an ameliorating agent for copper-contaminated soil, but it acted as a soil conditioner, increasing the morphological parameters of S. multijuga. In its initial development period, the S. multijuga species presented low copper phytostabilization potential in contaminated soil.

“…In ectomycorrhizal isolates, the response was quadratic positive, with an increase of 6% when the UFSC-PT116 isolate was inoculated at the Cu dose of 211.50 mg kg -1 of soil. Dellai et al (2014) reported that the stem diameter of the M. scabrella was significantly reduced when inoculated with the UFSC-PT116 fungus, which indicates that the response of this isolate is influenced by the plant species in association. However, for transplanting the seedlings to the field, a minimum neck diameter of 2 mm is recommended (Wendling and Dutra, 2010) and, in this case, all treatments have adequate values at the Cu doses studied.…”

“…The use of mycorrhizal fungi may be an alternative to improve plant development in contaminated areas (Dellai et al, 2014). These fungi form symbiotic associations with vascular plants increasing the area explored by the roots through their hyphae in the soil (Brundrett, 2008;Smith and Read, 2008).…”

Copper (Cu) is one of the main heavy metals contaminating the soil. Plants have different behavior in terms of tolerance and toxicity to metals, being able to grow and produce even in soils contaminated with high concentrations. This study aimed to determine the influence of ectomycorrhizal fungi on the growth and tolerance of yerba mate plants grown in soil contaminated with Cu. The design was completely randomized in a factorial arrangement (4x6), with four possibilities of inoculum: without inoculum (control) and three ectomycorrhizal fungi (UFSC-PT116 — Pisolithus microcarpus, UFSC-PT132 — Pisolithus tinctorius and UFSC-SU118 — Suillus cothurnatus), with six Cu doses amended to the soil (0, 80, 160, 240, 320 and 400 mg kg-1 of Cu) in seven replicates. The height of the aerial part, the diameter of the lap, the dry mass of the aerial part and root system, the leaf area, the specific surface area of the roots, the contents of Cu in the aerial and radicular parts, the tolerance index, and mycorrhizal association were assessed. Inoculation of Ilex paraguariensis seedlings with ectomycorrhiza fungi UFSC-PT116, UFSC-PT132, and UFSC-SU118 mitigates the toxicity effect caused by the excess of Cu in the soil. The UFSC-PT116 isolate promoted the highest growth and tolerance of Ilex paraguariensis seedlings under the treatments. In general, the isolates promoted the reduction of Cu toxicity in Ilex paraguariensis plants, being an important alternative to remediate Cu-contaminated areas.
