“…Thus, despite numerous reports on the toxicity of Cr(VI) towards plants, it is worthwhile to estimate the extent of the negative impact of this element on Zea mays through the prism of a wider array of parameters. The inhibited production of the aerial and root yields of maize, evidenced by the coefficients of the correlation between the dose of Cr(VI) and the yield of aerial organs (r = −0.984) and roots (r = −0.985), has been verified by other scholars, for example Mohammed et al [69], who observed that oxyanions not only diminished the biomass of the plant's roots but also decreased the rate of its germination, or Poltis [70], who showed that exposure to Cr(VI) contributed to a decrease in the length of roots and aerial parts of the plant by 25% and 75%, respectively. Wyszkowska et al [26] demonstrated in their study that Cr(VI) was just as toxic to Zea mays.…”

One of the major challenges faced by contemporary agriculture is how to achieve better yields of crops and, consequently, higher biomass, even in unfavorable environmental conditions. This challenge corresponds to the assumptions of sustainable development, wherein it is envisaged that plant biomass should be used on a large scale for heat generation or conversion of biofuels. Keeping pace with observed trends, the following study was conducted in order to determine the effect of Cr(VI) on the net calorific value of Zea mays, to assess the impact of this element on soil enzymatic activity, and to identify the effectiveness of compost and humic acids in alleviating possible negative effects of Cr(VI) toxicity. These aims were pursued by setting up a pot experiment, in which soil either uncontaminated or contaminated with increasing doses of Cr(VI) of 0, 15, 30, 45, and 60 mg Cr kg−1 d.m. was submitted to biostimulation with compost and the preparation HumiAgra, a source of humic acids, and cropped with Zea mays. The plant height, yield, and net calorific value of the aerial parts of maize, as well as its root yield, were determined. Additionally, the activity of seven soil enzymes and the values of the impact indices of compost and HumiAgra relative to the analyzed parameters were determined. It was found that Cr(VI) decreased the amount of energy obtained from the plants by decreasing maize biomass, and additionally by distorting the biochemical balance of the soil. Dehydrogenases, urease, and arylsulfatase proved to be particularly sensitive to this element. It was demonstrated that HumiAgra was more effective than compost in mollifying the adverse effects of Cr(VI) on the activity of soil enzymes and, consequently, on the biomass of Zea mays.

Heavy metals are widely available in the environment due to the natural processes, industrial, anthropogenic activities and ultimately in the results contaminate the immediate environment. The presence of the heavy metals such as Pb, Cd, Cr, Ni, Fe and Cu in environment disturb the quality of ecosystems, soils, water, air and vegetation. The chromium metal at higher level in ecosystem is an alarming signal for both developed and developing countries. Pennisetum glaucum is an annual grass which is widely cultivated in drought, rain fed and high temperature areas. The limited amount of literature available on the impact of chromium stress on P. glaucum. This study was conducted to investigate the beneficial or harmful effect of chromium stress on seed germination and seedling growth performances of P. glaucum in in vitro conditions. The different concentration of chromium 0, 25, 50, 75 and 100 ppm was applied. In present study, the overall results suggests the variable response on the rate of seed germination percentage and plant growth of P. glaucum to chromium stress was recorded. Results showed that the chromium treatment at 25 ppm significantly (p<0.05) reduced root growth of P. glaucum. The chromium at 50 ppm level significantly decreased the rate of percentage of seed germination of P. glaucum. The seedling dry weight of P. glaucum seedling was decreased highly at 75 ppm chromium. Root / shoot ratio also decreased due to gradual increase in chromium from low (25 ppm) to higher (100 ppm) levels. Similarly, the chromium at 25 to 100 ppm gradually decreased the percentage of tolerance and seedling vigor index of P. glaucum. An effective efforts for minimize the chromium toxicity and tolerance in plants are required.

“…The present investigation indicated that increasing concentrations of soil-applied Cr caused a significant and progressive reduction of plant growth. It was previously reported that an increased concentration of HMs can negatively impact the structure of root cell membranes and hinder the absorption of water and minerals [62,63]. Cr stress can also lead to various physiological problems, such as reduced transpiration, respiration, and photosynthesis, i.e., metabolism unbalance [64], ultimately resulting in stunted plant growth [15,19,52,65].…”

An excessive amount of chromium in soil has detrimental effects on plant processes, and impairs food security, and public health. The application of nanoparticles may be a suitable solution and an innovative strategy by which to reduce plant abiotic stresses and pollution in the agricultural ecosystems. This research focuses on the effects of chitosan nanoparticles (CS-NPs) on thyme (Thymus vulgaris L.) plants grown in Cr-contaminated soil. The effects of CS-NPs as a soil amendment at four concentrations were investigated on plant nutrient uptake, photosynthesis parameters, antioxidant system, and essential oil (EO) content under soil Cr stress. The results show that chromium stress reduced fresh and dry weight of shoots, the uptake of macro-, and micro-elements, chlorophyll and carotenoids. The application of CS-NPs improved the antioxidant enzyme activity, reduced malondialdehyde, and increased the content of nutrients, EOs, photosynthetic pigments, and chlorophyll fluorescence parameters. The intermediate dose of chitosan nanoparticles (0.1% w/v) best valorized the content and yield of thyme EOs under chromium stress. These results are indicative that the application of CS-NPs can represent a supportive approach for plant production in soils contaminated with heavy metals.
