“…The heavy metals cause toxicity and also generate oxidative stress in plant cell by interfering with the antioxidant defense system [ 47 – 49 ]. The cadmium affects the biomass and plant height in plant species such as Gossypium hirsutum and Cichorium pumilum [ 50 , 51 ]. In our study, P. dactylifera plants were harvested at 90 days after Cd treatment to investigate its effect using the biochemical and molecular approaches.…”

The cadmium (Cd), a heavy metal, causes toxicity, which leads to hampering the growth and development of the plant. The molecular and biochemical approaches were used for the investigation of antioxidant system response and genotoxicity in date palm (Phoenix dactylifera L.) cv. Sagai in pot experiment having Cd. The root length was more affected than the shoot length as more accumulation of Cd occurs in roots. Fresh weights of root and shoot were reduced significantly in treated plants as compared to the control. The proline content was increased at low concentration of Cd (300 µM-CdCl2) than the medium and high concentrations (600 and 900 µM-CdCl2), respectively. The thiobarbituric acid reactive substances (TBARS) content was increased at 600 and 900 µM-CdCl2 compared to the plants treated at 300 µM-CdCl2 and controls. Antioxidant enzymatic assay was performed under Cd stress and compared with control plants. The catalase (CAT) and superoxide dismutase (SOD) activities were found to be high in plants treated with CdCl2 at 300 µM compared to at 600 and 900 µM-CdCl2, respectively. The genotoxicity of Cd was assessed using the inter-simple sequence repeat (ISSR) marker where all treated and control plants were clustered into three main groups based on genetic similarity. P. dactylifera plants were found to be more divergent at high Cd stress as compared to control and plants treated at low concentration of Cd.

“…According to Rizwan et al (2017) the reduction in the plant growth and biomass under stress by Cd depends on the plant species, as well as on the dose and period of exposure to the metal. The decrease in fresh mass of the aerial part and root was also found in the genus Cichorium by Khateeb (2014), who observed a reduction in fresh weight in Cichorium pumilum (dwarf chicory) and root growth using Cd doses of 0 to 1600 µM (180 mg kg -1 ).…”

Some vegetables have the ability to accumulate cadmium (Cd) at levels that are toxic to most other plants. The objective of this study was to evaluate the Cd accumulation and its toxic effects on edible vegetables. Three species were tested: watercress (Barbarea verna); chicory (Cichorium endivia); rocket (Eruca sativa) and four Cd doses (0; 1.5; 3.0; 6.0 mg kg -1 ), with three replications. We evaluated Cd concentration, fresh and dry mass and SPAD index. We calculated tolerance index (TI), translocation index (TR) and the transfer coefficient (TC). Rocket, chicory and watercress are susceptible to Cd contamination and chicory presented visual symptoms of toxicity (chlorosis and mass loss).The Cd contents above those allowed were 0.6; 0.56 and 1.03 mg kg -1 in rocket, watercress and chicory, respectively, these values were reached by applying doses from 1.5 mg kg -1 for rocket and 3 mg kg -1 for watercress and chicory.
