“…Although the studied species do not present characteristics of hyperaccumulation species, they were adapted to the vineyard environments. On the other hand, there is a need for conduct further research on genotypes or species for phytoremediation in South America, including native species that showed great potential for Cu removal (Marques et al., 2022; Silva et al., 2020).…”

Vineyard soils can be contaminated by copper (Cu) due to successive applications of fungicides and organic fertilizers. Soil remediation can be addressed by altering soil properties or selecting efficient Cu‐extracting cover crops tolerant to Cu toxicity. Our objectives were to synthesize the Cu‐extracting efficiency by plant species tested in Brazil, classify them according to Cu resistance to toxicity, and assess the effect of soil properties on attenuating Cu toxicity. We retrieved results from 41 species and cultivars, totaling 565 observations. Freshly added Cu varied between 50 and 600 mg Cu kg−1 of soil across studies. The partition of Cu removal between the above‐ and below‐ground portions was scaled as a logistic variable to facilitate data synthesis. The data were analyzed using the Adaboost machine learning model. Model accuracy (predicted vs. actual values) reached R2 = 0.862 after relating species, cultivar, Cu addition, clay, SOM, pH, soil test P, and Cu as features to predict the logistic target variable. Tissue Cu concentration varied between 7 and 105 mg Cu kg−1 in the shoot and between 73 and 1340 mg Cu kg−1 in the roots. Among soil properties, organic matter and soil test Cu most influenced the accuracy of the model. Phaseolus vulgaris, Brassica juncea, Ricinus communis, Hordeum vulgare, Sorghum vulgare, Cajanus cajan, Solanum lycopersicum, and Crotolaria spectabilis were the most efficient Cu‐extracting cover crops, as shown by positive values of the logistic variable (shoot removal > root removal). Those Cu‐tolerant plants showed differential capacity to extract Cu in the long run.

“…Heavy metal phytotoxicity encompasses a wide range of morphological, biochemical and physiological changes leading to a reduction in plant growth (De Conti et al 2018, 2021, on an extent dependent on the concentration and chemical forms of the contaminants in the soil, associated to exposure time and constitutive and adaptive mechanisms of tolerance of the plants (Barcel o and Poschenrieder 1992). Some plant species survive in heavy metal contaminated environments due to tolerance mechanisms (Silva et al 2020), such as retention of the contaminants in the roots, compartmentalization in less susceptible cellular organelles such as the vacuoles, root exudation of the toxic compound and intracellular production of substances able to form stable complexes (Ferreira et al 2014).…”

“…Spontaneous cover vegetation surviving in vineyard soils containing high levels of Cu may accumulate the metal and increase the levels of organic matter in the soil, thus reducing the bioavailability of the contaminant to grapevine (Silva et al 2020). Therefore, a strategy to reduce Cu toxicity is seeding the spontaneous plants or maintaining them naturally in the vineyard to mitigate the phytotoxicity (Gardea-Torresdey et al 2004;Ariyakanon and Winaipanich 2006;Nouri et al 2009;Lorestani et al 2011;Silva et al 2020). This strategy can be performed by phytoremediation, using the plants to remove or reduce the toxicity of contaminant elements in soil (De Conti et al 2018Conti et al , 2019.…”

“…Species with phytoremediation potential should be tolerant to contaminants and able to accumulate heavy metal in the biomass in order to contribute to reducing the availability of these elements in the soil. Ideally, phytoremediation species should also grow fast, produce high biomass and have low nutritional requirements (Ferreira et al 2014;De Conti et al 2019;Silva et al 2020).…”

Copper (Cu) contents in vineyard soils due to the application of cupric fungicides cause changes in the native covering flora. Under these conditions, the surviving individuals accumulate the metal in and decrease its availability in the soil, reducing the potential toxicity to grapevine. We have identified spontaneous plant species and their phytoremediation potential from vineyards of Isabella (Vitis labrusca) on two distinct soil types (Inceptisol and Entisol) contaminated with Cu. The results demonstrated that wild species displayed higher Cu contents in the roots than in the shoot, but had low bioaccumulation potential. During summer, the plants were unable to extract and stabilize the metal, although during the winter, Lolium multiflorum, Cyperus compressus and Chrysanthemum leucanthemum demonstrated phytostabilization potential. Among the investigated species, dry matter production and Cu accumulation by Lolium multiflorum indicated that the species is effective to decrease Cu availability in the soil.

The aims of the present study are to evaluate whether the growth of Pampa biome native grass species Axonopus affinis, Paspalum notatum and Paspalum plicatulum, as well as of invasive grass species Cynodon dactylon, is compromised by excessive Cu availability in the soil (0, 35 and 70 mg of Cu kg-1), to determine the impact of excessive Cu on the physiological responses of the investigated species and to assess whether these species have the potential to enable the phytoremediation of soils contaminated with Cu. C. dactylon presented the best performance in soil contaminated with 35 mg of Cu kg-1. In C. dactylon, the concentrations of chlorophyll b and carotenoids increased, as did the photosynthetic rate and plant growth. Phytotoxic effects of Cu in soil contaminated with 70 mg of Cu kg-1 were more severe on A. affinis and led to plant death. The other species presented reduced photosynthetic and growth rates, as well as increased activity of antioxidant enzymes such as SOD and POD. This very same Cu level has decreased photosynthetic pigment concentrations in P. notatum and P. plicatulum. On the other hand, it did not change chlorophyll a and b concentrations in C. dactylon and increased carotenoid concentrations in it. High values recorded for Cu bioaccumulation-in-grass-root factor, mainly in P. plicatulum, have indicated that the investigated plants are potential phytostabilizers. High C. dactylon biomass production - in comparison to other species - compensates for the relatively low metal concentration in its tissues by increasing metal extraction from the soil. This makes C. dactylon more efficient in the phytoremediation process than other species.
