“…MDA is the end product resulting from lipid peroxidation of extra free radicals, and the concentration of MDA is an important index of physiological stress . The change of MDA content indicates the degree of membrane damage of plant cells by stress . Nimptsch and Pflugmacher found a reduced content of MDA in Myriophyllum mattogrossense under ammonia stress.…”

In order to investigate the impacts of ammonia nitrogen concentration and the necessity of dredging, five levels of ammonia nitrogen including 0, 2, 4, 8, and 16 mg L−1 and two levels of sediments nutriments (high and low) were treated. The total biomass, leaf, root, and flower biomasses were selected as the growth indicators, while total chlorophyll (i.e., chl‐a and ‐b), malondialdehyde (MDA), and free proline as subsidiary physiological index. When ammonia‐N contents of the water column were 8–16 mg L−1, the total biomass of Vallisneria natans in the first harvest is higher than those in the second harvest, and the total chlorophyll concentration, MDA and free proline of the plants became significantly low. It indicates that high ammonia nitrogen (>8 mg L−1) of the water column inhibit the growth of V. natans. The total biomass, the total chlorophyll concentration of plants in the high nutrient sediment is higher than those in the low nutrient sediment, suggesting that high sediments nutrient promote the growth of V. natans. Therefore, using V. natans for water ecological restoration, the water should meet the ammonia nitrogen content of <8 mg L−1. Moreover, dredging eutrophication sediment is probably not necessary.

“…[21][22][23][24] We have reported previously on the potential for this species to restore degraded ecosystems and demonstrated its tolerance to cadmium and nickel (Ni), and the mechanisms of these tolerances, under laboratory conditions. [25,26] The aim of this study was to examine the suitability of V. olympicum as a potential candidate for phytoremediation of Cu-contaminated soils. In this regard, the contents of a variety of trace elements ( ) in plant tissues were analysed to evaluate the accumulation and translocation patterns of V. olympicum under Cu stress.…”

The aim of this study was to evaluate the effects of copper (Cu) stress on accumulation and transport of trace elements, nitrogen assimilation, and growth parameters of Verbascum olympicum. Eight-week-old seedlings were grown in Hoagland's solution and exposed to 0, 50, 250, or 500 µM CuSO 4 for seven days in laboratory conditions. Bioaccumulation of trace elements (boron, bismuth, cobalt, Cu, iron, lithium, manganese, molybdenum, nickel, lead, zinc) in the roots and leaves was determined by inductively coupled plasma-mass spectrometry after one, three, and seven days. Chlorophyll content, nitrate reductase, and glutamine synthetase activities, soluble protein content, and biomass were determined. Copper accumulated in the roots and leaves (up to 19609.8 and 256.2 mg kg −1 dry weight, respectively). Other trace elements accumulated to higher levels in the roots of Cu-treated plants compared with those of control plants. High Cu concentrations decreased nitrogen-assimilatory enzyme activities. Compared with control plants, those treated with high Cu concentrations showed lower chlorophyll contents, total protein contents, and biomass. Nitrogen assimilation and growth parameters of V. olympicum were negatively affected by Cu treatment but mineral nutrition was not severely disrupted. The results support the suitability of V. olympicum as a candidate for phytoremediation of Cu-contaminated soils.

Verbascum olympicum Boiss. (Scrophulariaceae) were studied as a candidate plant for remediating the Ni polluted soils. The metabolic responses, such as nitrate assimilation (nitrate reductase and glutamine synthetase activity) and antioxidant system activity [superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (APX) activity], of this species exposed to nickel in Hoagland's nutrient medium were investigated as remediation performance parameters. The accumulation of nickel and the variations in the content of some elements (B, Cu, Fe, Mg, Mn, Mo and Zn) and some growth parameters, such as the water content, biomass production, and contents of chlorophyll and soluble protein, were also examined. The accumulation of Ni in both the roots and leaves varied depending on the exposure times and doses. Increased oxidative stress was suggested by the increases in the activities of SOD, CAT and APX. Although some element contents were inhibited by Ni treatments, these inhibitory effects was decreased depending on the time, and even these elements are accumulated in roots. These results are the novelties in the use of this species in biotechnology.
