“…It has been found that under different aeration measures, planting plants can effectively remove the ammonium nitrogen content in the eutrophic water head. The NH 4 + -N removal rate of cattail is 99.9%, and the NH 4 + -N removal rate of chlorophytum comosum was about 97.0% [20][21]. This is consistent with the results of this study.…”

With the development of cities and economic growth, the eutrophication of urban park landscape water has become a hot topic in environmental governance and research at home and abroad. Through the simulation experiment of water pollution, the effect of plant micro system built by aquatic plant on the ability of algae suppression in eutrophic water was studied. The results show that the micro system formed by different types of water plant can be reduced and stabilized the pH value of the rich and enriched water bodies. The pH of Lythrum salicaria L. group (Q) and Iris tectorum Maxim group (Y) group is the lowest. They are 7.34 and 7.48, which is significantly lower than the plant less group (CK). Different treatments have effectively reduced the nitrogen and phosphorus content in the water body. At the end of the experiment, the total nitrogen content of Y dropped from 9.49 to 3.21 mg∙L− 1, and the removal rate reached 66.2%; the total phosphorus removal rate of the water body phosphorus of different types of aquatic plants was 59.1%⁓81.3%, which was significantly higher than that of CK. Among them, the total phosphorus removal rate of Y treatment is the best, and it is significantly different from the CK. At the end of the experiment, chl a content in group Y was the lowest which was 6.6 mg∙L− 1. It decreased by 37.1% and 54.1% compared to the initial value and CK, respectively. It showed significant differences compared to other treatments (P < 0.05). At the same time, the content of proline and malondialdehyde in plants of Y, Q, and Nelumbo SP. group(H) significantly increased in eutrophic water, with group Y plants showing the highest increase, with increases of 28.6% and 39.8%, respectively. Different micro-systems formed by different water plants can improve water quality conditions and inhibit the reproduction of algae in the water. Among them, the effect of planting Iris tectorum Maxim group is the best.

“…As the human living standards and urban landscapes improve, more and more ornamental plants are widely used for gardening and greening in urban areas [1,55,56]. Ornamental plants have surrounded humans living environmentally since the Neolithic period and have appeared in early Chinese poems and paintings, Egyptian pyramid morals and European history, indicating that humans have a long history of being attracted to ornamental plants [57,58]. Nowadays, ornamental plants, especially flowering plants, are an important part of urban forests, which are planted across all urban areas for enhancing the visual and aesthetic quality of the architectural environments, tolerating the stress of copper (Cu), deicing reagents and drought stress, improving the air quality and fungal disease management, remediating the pollution of on-site greywater, eutrophication, ozone, VOCs, lead (Pb), tin (Sn) and petroleum hydrocarbons [59][60][61][62][63][64][65][66][67][68][69].…”

Cadmium Uptake and Growth Responses of Seven Urban Flowering Plants: Hyperaccumulator or Bioindicator?

et al. 2022

The application of flowering plants is the basis of urban forest construction. A newly-found flowering hyperaccumulator is crucial for remediating urban contaminated soil sustainably by cadmium (Cd). This study evaluated growth responses, Cd uptake and bioaccumulation characteristics of seven urban flowering plants. Based on growth responses of these plants, Calendula officinalis L. showed high tolerance to at least 100 mg kg−1 Cd, in terms of significant increase in biomass and with no obvious changes in height. After 60 d exposure to 100 mg kg−1 Cd, the accumulated Cd in shoots of the plant reached 279.51 ± 13.67 μg g−1 DW, which is above the critical value defined for a hyperaccumulator (100 μg g−1 DW for Cd). Meanwhile, the plant could accumulate Cd to as much as 926.68 ± 29.11 μg g−1 DW in root and 1206.19 ± 23.06 μg g−1 DW in plant, and had higher Cd uptake and bioaccumulation values. According to these traits, it is shown that Calendula officinalis L. can become a potential Cd-hyperaccumulator for phytoremediation. By contrast, Dianthus caryophyllus L. is very sensitive to Cd stress in terms of significantly decreased biomass, height and Cd uptake, indicating the plant is considered as a Cd-bioindicator.

“…Nowadays, more and more ornamental plants are widely used for gardening and greening across the human living environment [57][58][59]. Ornamental plants not only clean up the soil contaminated by heavy metals but also contribute to the beautification and decoration of the living environment [60,61].…”

The multi-system of electro-phytotechnology using a woody ornamental cadmium (Cd) hyperaccumulator (Lonicera japonica Thunb.) is a new departure for environmental remediation. The effects of four electric field conditions on Cd accumulation, growth, and photosynthesis of L. japonica under four Cd treatments were investigated. Under 25 and 50 mg L−1 Cd treatments, Cd accumulation in L. japonica was enhanced significantly compared to the control and reached 1110.79 mg kg−1 in root and 428.67 mg kg−1 in shoots influenced by the electric field, especially at 2 V cm−1, and with higher bioaccumulation coefficient (BC), translocation factor (TF), removal efficiency (RE), and the maximum Cd uptake, indicating that 2 V cm−1 voltage may be the most suitable electric field for consolidating Cd-hyperaccumulator ability. It is accompanied by increased root and shoots biomass and photosynthetic parameters through the electric field effect. These results show that a suitable electric field may improve the growth, hyperaccumulation, and photosynthetic ability of L.japonica. Meanwhile, low Cd supply (5 mg L−1) and medium voltage (2 V cm−1) improved plant growth and photosynthetic capacity, conducive to the practical application to a plant facing low concentration Cd contamination in the real environment.
