“…This was in consistent to the results reported by Citterio et al (2003) and Linger et al (2005). The high tolerance of hemp plants to 25-100 mg kg -1 Cd stress was illustrated by the small reduction of roots and shoots biomass, little inhibition in photosynthesis, and less oxidative stress maintained by POD and SOD.…”

To assess the role of salicylic acid (SA) in alleviating cadmium (Cd) toxicity in hemp (Cannabis sativa L.) plants, the growth parameters, Cd accumulation, photosynthetic performance and activities of major antioxidant enzymes were investigated in hemp seedlings treated with 500 lM SA, under 0, 25, 50, and 100 mg Cd kg -1 sands (DW) conditions, respectively. Cd exposure resulted in a small reduction in biomass (12.0-26.9% for root, and 8.7-29.4% for shoot, respectively), indicating hemp plants have innate capacity to tolerant Cd stress. This was illustrated by little inhibition in photosynthetic performance, unchanged malondialdehyde content, and enhancement of superoxide dismutase (SOD) and peroxidases (POD) activities in hemp plants. Cd content in root is 25.0-29.5 times' higher than that in shoot, suggesting the plant can be classified as a Cd excluder. It is concluded that SA pretreatment counteracted the Cd-induced inhibition in plant growth. The beneficial effects of SA in alleviating Cd toxicity can be attributed to the SA-induced reduction of Cd uptake, improvement of photosynthetic capacity, and enhancement of SOD and POD activities.

“…Previous studies demonstrated that hemp is a metal-tolerant organism, and the amount of Cd accumulated in its shoot was not negligible (Linger et al 2002(Linger et al , 2005Citterio et al 2003). However, little is known about the mechanism of Cd tolerance.…”

“…Phytotoxicity of chromium is considered inhibitory for plant growth. Its presence in surplus amount inside the plant can cause stunted growth [16][17][18]. The presence of chromium in soil disturbs the pattern of nutrient uptake in plant because of nutrient metal interaction [19,20].…”

Chromium is found in all phases of the environment, including air, water and soil. The contamination of environment by chromium has become a major area of concern. Chromium effluent is highly toxic to plant and is harmful to their growth and development. In present study, a pot experiment was carried out to assess the phytotoxicity of chromium in Hibiscus esculentus at different concentration (0.5, 2.5, 5, 10, 25, 50 and 100 mg·kg ) of chromium metal. The phytotoxic effect of chromium was observed on seed germination, seedling growth, seedling vigor index, chlorophyll content and tolerance indices of Hibiscus esculentus. All results when compared with control show that chromium metal adversely affects the growth of Hibiscus esculentus by reducing seed germination and decreasing seedling growth. The toxic effects of chromium metal to seed germination and young seedling are arranged in order of inhibition as: 0.5 > 2.5 > 5 > 10 > 25 > 50 > 100 mg·kg −1 respectively. The toxicity of chromium metal to young seedling and their effects on chlorophyll content were increased with higher concentration of chromium in the soil system. The major inhibitory effect of chromium in Hibiscus esculentus seedling was determined as stress tolerance index (%). The present study represents that the seed and seedling of Hibiscus esculentus has potential to counteract the deleterious effects of chromium metal in soil.

“…A probable explanation is that high amount of Cd was likely to precipitate with phosphate deposit on the root surface or in the apoplast due to high concentration of phosphate in Hoagland solution. When the Cd concentration in medium is high under hydroponic culture conditions, the plant intracellular accumulation rate is lower than the metal sorption by the root apoplastic pathway (Citterio et al 2003). Nedelkoska and Doran (2000) suggested that Cd uptake by fine roots was due to sorption rather than intracellular mechanisms.…”

Cadmium concentrations in two plant species and their corresponding soils were evaluated in a metal contaminated area. The average Cd concentrations reached 36.9 and 141 mg kg(-1) in Solanum nigrum leaves and Lobelia chinensis shoots, respectively. There is a significant relationship between the Cd concentration in the aerial tissues and the corresponding soils on a logarithmic scale. Under the hydroponic culture conditions, the maximum Cd concentration in the S. nigrum leaves and L. chinensis shoots were 1,110 and 414 mg kg(-1), respectively. Cd concentration was higher in the roots than in the aerial parts. The two plants may be used in suitable phytoremediation process.
