“…For all tested rice varieties the mean shoot Cd content was increased significantly with increasing soil Cd levels. It has been reported that the average Cd accumulation in rice roots were much higher than in stems and leaves and rice grains (Liu et al, 2003). The present study too confirmed this phenomenon; it showed that all the tested rice varieties accumulated Cd in the sequence of grain < shoot < root for every soil Cd level treated i.e.…”

“…The significant positive correlation between Cd or Pb and Zn in water spinach genotypes may indicate that they have similar uptake mechanisms. Similar results were reported in previous studies (Wu and Zhang, 2002;Liu et al, 2003;Dong et al, 2006;Li et al, 2015). These heavy metals are probably transported by similar transporters in the form of compounds or chelate complexes, and the mobilizing function of root exudates is effective not only for Cd but also for Pb and Zn (Kabata-Pendias, 2011).…”

Abstract:Vegetables are important constituents of the human diet. Heavy metals and nitrate are among the major contaminants of vegetables. Consumption of vegetables and fruits with accumulated heavy metals and nitrate has the potential to damage different body organs leading to unwanted effects. Breeding vegetables with low heavy metal and nitrate contaminants is a cost-effective approach. We investigated 38 water spinach genotypes for low Cd and nitrate co-accumulation. Four genotypes, i.e. JXDY, GZQL, XGDB, and B888, were found to have low co-accumulation of Cd (<0.71 mg/kg dry weight) and nitrate (<3100 mg/kg fresh weight) in the edible parts when grown in soils with moderate contamination of both Cd (1.10 mg/kg) and nitrate (235.2 mg/kg). These genotypes should be appropriate with minimized risk to humans who consume them. The Cd levels in the edible parts of water spinach were positively correlated with the concentration of Pb or Zn, but Cd, Pb, or Zn was negatively correlated with P concentration. These results indicate that these three heavy metals may be absorbed into the plant in similar proportions or in combination, minimizing the influx to aerial parts. Increasing P fertilizer application rates appears to prevent heavy metal and nitrate translocation to shoot tissues and the edible parts of water spinach on co-contaminated soils.

“…In almond seedlings, Cd toxicity caused a significant decline in essential macronutrients including Ca, K, Mg (Nada et al, 2007). Liu et al (2003) reported that Cd had synergistic interaction with the uptake and translocation of different nutrients, including Fe, Cu and Zn in rice. Similarly, Yang et al (2011) recorded Cd-induced decline in macronutrients (K and P) in Potamogeton criprus.…”

“…However, contradictory results have been found in the literature. Thus, further studies are needed to investigate the interactions between contaminants and nutrients in order to favour selection for enhanced uptake efficiency of desirable nutrients and reductions in the uptake of undesirable ones (Liu et al, 2003).…”

Cadmium (Cd) toxicity causes leaf chlorosis, growth inhibition, and disruption of photosynthetic machinery. A pot experiment was conducted to evaluate the changes in growth, physiochemical attributes and expression level of the catalase (Cat2) gene in two tomato cultivars (cv. Nagina; cv. Roma) under cadmium (Cd) stress. Plants were subjected to various concentrations of Cd in soil medium (0, 160, 320, 640 and 1280 μM Cd) in full strength Hoagland nutrient solution. Elevated Cd concentrations caused an apparent turn down in plant growth, photosynthetic pigments, and activity of CAT and increased the level of ascorbic acid, proline, H 2 O 2 and malondialdehyde (MDA) and ascorbate peroxidase (APX) peroxidase (POD) activities. The fruit biomass, moisture content, total fiber, protein, glucose and fructose contents were decreased. In addition, Cd induced alterations in some nutrient elements; for instance, Ca 2+ decreased and K + in fruit was increased in response to Cd toxicity. Cadmium contents in fruit decreased evidently under elevated levels of Cd. The results of the present study demonstrated that Cd toxicity severely deteriorated the fruit quality, whereas the cultivar that showed greater Cat2 gene expression and had low H 2 O 2 and MDA contents tolerated Cd stress effectively. Fruit quality of cv. Nagina was better than cv. Roma. In this context, we have recorded greater ash, fiber and protein contents in cv. Nagina, while cv. Roma was inferior in this regard under cadmium toxicity.
