“…Nevertheless, high concentrations of Zn are toxic and hamper plant growth [3]. The excess of Zn affects the uptake of other nutrients, inhibiting seed germination, plant growth, and root development [10].…”

“…Moreover, a study with sunflower determined that seeds germinated at high Zn concentrations, while germination decreased to below 50% after exposure to Cd, Cu, and Pb [8]. Marichali et al (2014) achieved germination of C. sativum seedlings irrigated with high Zn concentrations at a pH of 6.8, but root length was reduced. They showed that, for C. sativum, Zn has low toxic effects on germination, and roots are more sensitive than seeds to metal stress [3].…”

“…Other metals like Hg, Pb, and Cd have never been shown to be essential for organism development and are toxic at low concentrations [2]. Environment pollution with heavy metals by increased industrialization and geochemical activities is a major environmental and human health problem [3] due to these metals' non-biodegradability and high toxicity [4].…”

“…From these elements, Pb and Cd are the pollutants most frequently found in the mining zones of the country [6]. Moreover, in soil, the metals of most concern are Cd and Zn, as they show the greatest mobility [3]. The environmental impact caused by the pollution in mining sites depends on the interaction capacity of metals with soil and water [1].…”

Germination of Bouteloua dactyloides and Cynodon dactylon in a Multi-Polluted Soil

Abstract:Mining wastes generate high environmental impacts, and population exposure to metals and metalloids. Phytoremediation is a technology that uses plants to remediate polluted sites, but one of its limitations is seed germination in soil with a high content of metals and metalloids. Bouteloua dactyloides (former Buchloe dactyloides) is a native species from semiarid regions, while Cynodon dactylon is an invasive species; both are tolerant to harsh soil conditions. The objective of this research was to evaluate the germination of both species, exposed to a multi-polluted soil with As, Cd, Pb, and Zn of a mining site, considering different pH conditions (from 5.0 to 9.0). The study considered four repetitions by type of seed and soil pH. The highest germination of B. dactyloides was 83% at pH 7.8, while the greatest germination of C. dactylon was 34% at pH 6.0. These percentages are similar to those obtained in a standard germination test, which are 82.5% for B. dactyloides and 35% for C. dactylon. Germination was not reached in either species with soil at pH 5, owing to the fact that metals are more bioavailable in acid environments. B. dactyloides and C. dactylon had a high potential to germinate in multi-polluted soil at neutral pH, but further experiments are needed.

“…From a physiological point of view, an increase in total phenol and flavonoid content is expected due to their ROS scavenging activity, Cu chelating and detoxifying properties (Gordon & RoedigPenman 1998). Phenolic components have been also shown to be upregulated in response to Cd (Mishra et al 2014), Zn (Marichali et al 2014), Al (Kováčik et al 2012), Pb (Wang et al 2011) and Ni (Kováčik et al 2009).…”

, in a Cu 2+ concentration-dependent manner. The treatment with copper gives rise to positive effects on antioxidant enzymes activities (SOD and CAT enzymes) and to an increase of total phenol and flavonoid contents. Unexpectedly, no correlation with the anti-radical scavenging activity was observed. Conclusions: Marrubium vulgare possess an intrinsic capability to cope with the Cu stress by activation of the enzymatic and non-enzymatic antioxidant systems.

Caraway (Carum carvi L.) is a medicinal and aromatic plant; its seeds (fruits) are used as spice and they contain essential oils. We hypothesized that by collecting caraway oil at different time points during the extraction process, we could obtain oil fractions with distinct chemical composition. A hydrodistillation time (HDT) study was conducted to test the hypothesis. The caraway seed oil fractions were collected at eight different HDT (at 0 - 2, 2 - 7, 7 - 15, 15 - 30, 30 - 45, 45 - 75, 75 - 105, and 105 - 135 min). Additionally, a non-stop HD for 135 min was conducted as a control. Most of the oil was eluted early in the HD process. The non-stop HDT treatment yielded 2.76% oil by weight. Of the 24 essential oil constituents, limonene (77 - 19% of the total oil) and carvone (20 - 79%) were the major ones. Other constituents included myrcene (0.72 - 0.16%), trans-carveol (0.07 - 0.39%), and β-caryophyllene (0.07 - 0.24%). Caraway seed oil with higher concentration of limonene can be obtained by sampling oil fractions early in HD process; conversely, oil with high concentration of carvone can be obtained by excluding the fractions eluted early in the HD process. We demonstrated a method of obtaining caraway seed oil fractions with various and unique composition. These novel oil fractions with unique composition are not commercially available and could have much wider potential uses, and also target different markets compared to the typical caraway essential oil.
