“…The possible reason behind it is H. cannabinus undergoes Cu stress for short period (14 days) while Bhattacharya et al (2014) noticed that short term metal stress causes metal accumulation in the roots while long term metal stress support plant to able to accumulate in the above ground parts. Although, BAF and TF cannot evaluate alone the phytoremediation of the plant, biomass of the plant is also important in screening the phytoremediation potential against stress tolerance (Chen et al, 2015a;Chen et al, 2015b). Similar results showed by Zaheer et al (2015) that short-term heavy metal application was highly accumulated in the roots while a little transported to the shoots.…”

“…Increased the activities of antioxidants in the roots and leaves of H. cannabinus under low level of Cu (60 and 120 µmol L −1 ) in the nutrient solution indicating that H. cannabinus could tolerate stress levels to a certain level by enhancing antioxidative defense system. The variable response of antioxidants on the roots and leaves of H. cannabinus might be due to the alteration in gene expression and function of various proteins associated with different physiological structure in plants (Chen et al, 2015a;Gao et al, 2017;Kohli et al, 2018). However, decreased in the activities of antioxidants under higher levels of Cu might be due to severe oxidative stress as previously reported by Habiba et al (2015).…”

“…The main reasons behind this is use of Cu-made agrochemicals, pesticides, fungicides, bactericides and nematicides which enhances crop yield and productivity and control pests but that are major sources of high concentration of Cu in agricultural soil (Husak, 2015;Rehman et al, 2019b). The phytotoxicity of Cu in reducing the growth and biomass of the plants has been reported in many previous studies (Celis-Plá et al, 2018;Chen et al, 2015a;Chen et al, 2015b;Gao et al, 2017;Liu et al, 2018;Rehman et al, 2019c;Zaheer et al, 2015). Toxic concentration of Cu in soil can cause nutrient imbalance by binding with organic matter, clay minerals, and hydrated oxides of iron (Fe), aluminum (Al), and manganese (Mn), which affects the plant productivity.…”

Kenaf (Hibiscus cannabinus L.) is a fibrous crop, grown in tropical climate having huge biomass and can be a good candidate for the phytoremediation of different heavy metals. Consequently, the present study was conducted to explore morpho-physiological traits, photosynthetic pigments, gaseous exchange attributes, antioxidative response and phytoextraction of copper (Cu) in H. cannabinus grown under different levels of Cu i.e. 0 (control), 60, 120 and 180 µmol L−1 in Hoagland nutrient solution (pH 6.2). The results from the present study revealed that Cu toxicity reduced plant height, plant diameter, plant fresh weight, plant dry weight, photosynthetic pigments and gaseous exchange attributes compared to control. Moreover, excess Cu in the nutrient solution ameliorates contents of malondialdehyde (MDA), hydrogen peroxide (H2O2) and electrolyte leakage (EL) which showed that Cu induced oxidative damage in the roots and leaves of H. cannabinus. The oxidative stress which was induced by a high concentration of Cu in the nutrient solution is overcome by enzymatic activities of antioxidants which increased with the increase in Cu concentration, i.e. 60 and 120 µmol L−1, while the addition of Cu (180 µmol L−1) caused a reduction in the activities of superoxidase dismutase (SOD), peroxidase (POD), catalase (CAT) and ascorbate peroxidase (APX) in the roots and leaves of H. cannabinus. The results also demonstrated that an increase in Cu concentration in the nutrient solution causes an increase in Cu accumulation through roots, leaves and stems of H. cannabinus, although the highest Cu concentration was accumulated in roots while only a little transported to the above ground parts (leaves and stems) of the plants. All the values of bioaccumulation factor (BAF) and translocation factor (TF) were less than 1, which also indicated that a small quantity of Cu concentration is transported to the aboveground part of the plants. These findings suggested that phytotoxicity of Cu affected plant growth and biomass and increased ROS production while accumulation of Cu in different parts of plant proved that H. cannabinus is an ideal specie for phytoremediation of Cu when grown under Cu contaminated sites.

“…Some key factors in Cu's high soil concentration are the use of fungicides, bactericides and herbicides in agriculture [2,11]. About 16% of the soil is polluted by heavy metals in China and only about 2.1% of the soil is tainted with Cu [3,17,18]. Cu is an essential micronutrient and also a cofactor of many enzymes such as peroxidase (POD) and superoxidase dismutase (SOD) [4,19,20].…”

Copper (Cu) is an important micronutrient for a plant’s normal growth and development. However, excess amount of Cu in the soil causes many severe problems in plants—which ultimately affect crop productivity and yield. Moreover, excess of Cu contents causes oxidative damage in the plant tissues by generating excess of reactive oxygen species (ROS). The present experiment was designed to investigate the phytoextraction potential of Cu, morpho-physiological features and biochemical reaction of jute (Corchorus capsularis L.) seedlings using ethylenediaminetetraacetic acid (EDTA) of 3 mM under different Cu levels (0 (control), 50 and 100 μM) in a hydroponic nutrient solution (Hoagland). Our results showed that elevated Cu rates (50 and 100 μM) in the nutrient solution significantly reduced plant height, fresh and dry biomass, total chlorophyll content and gaseous exchange attributes in C. capsularis seedlings. As the concentration of Cu in the medium increased (50 and 100 μM), the level of malondialdehyde (MDA) and oxidative stress in C. capsularis seedlings also increased, which could have been controlled by antioxidant activity in particular plant cells. In addition, rising Cu concentration in the nutrient solution also increased Cu uptake and accumulation in roots and leaves as well as affected the ultrastructure of chloroplast of C. capsularis seedlings. The addition of EDTA to the nutrient solution significantly alleviated Cu toxicity in C. capsularis seedlings, showing a significantly increase in plant growth and biomass. MDA contents was not significantly increased in EDTA-induced plants, suggesting that this treatment was helpful in capturing ROS and thereby reducing ROS in in C. capsularis seedlings. EDTA modification with Cu, although the bioaccumulation factor in roots and leaves and translocation factor for the leaves of C. capsularis seedlings has significantly increased. These results indicate that C. capsularis has considerable potential to cope with Cu stress and is capable of removing a large quantity of Cu from the Cu-contaminated soil while using EDTA is a useful strategy to increase plant growth and biomass with Cu absorption capabilities.

“…A study (Bian et al., 2017) likewise reported its high accumulation abilities in soils contaminated with copper, cadmium, and zinc. Other reports also confirmed the potential of the said species to accumulate copper, zinc, cadmium and lead in the roots, shoots, and leaves in hydroponic set-ups (Bin et al., 2017; Chen et al., 2014, 2015a, 2015b; Li et al., 2015; Zhang et al., 2010).…”

A B S T R A C TThe phytoremediation potential of three bamboo species, i.e. Bambusa merilliana, Bambusa blumeana, and Dendrocalamus asper, were evaluated for their total Cu uptake ability in hydroponics. Dendrocalamus asper proved to be the most efficient in terms of Cu phytoremediating potential with a constant positive uptake of 80 μM in a contaminated substrate and a bioconcentration factor of 50.57. Copper accumulation was found to concentrate the most in the roots compared to the amount translocated in the shoots. Analysis of the Cu uptake of D. asper roots at varying concentrations of Cu contamination (40, 80 and 120 μM) allowed for the fitting of the kinetics of Cu uptake and removal with existing kinetic models. The rate of copper removal per mass of plant was the best for the 0 th order model in the 80 μM solution with an R 2 of 0.954 and rate constant of 3.136 mg-kg À1 d À1 . The accumulation of Cu within the roots on day 7 (7d) followed the Michaelis-Menten model with an R 2 of 0.970. The Michaelis-Menten constant (K M ) was 4.87 mg/L and maximum accumulation velocity (Vmax) was 66.26 mg Cukg À1 -day À1 . Results suggest that D. asper is a potential hyperaccumulator plant that can be used in clean-up of domestic and industrial wastes present along river systems in the Philippines.
