“…The inhibitory effect of metals on cell expansion and division might be due to inhibition of growth promoters primarily through blocking enzyme activation and lowering or direct blocking of cell division by intrusive with the cell membrane integrity [13]. These results of present study agreed with findings on the Cluster Bean [14] wheat [10] the Psyllium and on Mung bean .…”

Studies on Seed Germination in Capsicum Seeds (Solan Bharpur) under Abiotic Stress

Plants often experience abiotic stress like salinity, drought, high or low temperature, flooding, metal toxicity, ozone, UV-radiations, herbicides, etc., which pose serious threat to the crop production. Germination studies showed that heavy metal exposure caused a decrease in seed germination and at higher doses the seeds failed to germinate. This was confirmed by root length and shoot length. Ascorbic acid content was found to be decreased in all the treatment groups. However the phenol content was found to be decreased significantly with increasing concentrations of metals. There was considerable increase in phenolic content in water logging conditions. Metal treatment also led to an increase in catalase activity, thus showing that abiotic stress induced oxidative stress in the plants and antioxidants tend to neutralize this stress.

“…Inside the roots at least three processes can occur: phytostabilization, phytodegradation, and phytoaccumulation (Schnoor et al 1995;McCutcheon and Schnoor 2003;Singh et al 2007). The initial and final soil chromatograms established that rhizodegradation and perhaps phytodegradation occurred.…”

Petroleum exploitation in oilfields, especially drilling, generates an oily sludge mixed with hydrocarbons and mineral solids. This oily sludge is sometimes treated by bioremediation and phytoremediation. This investigation established that landfarmed oil sludge provided adequate soil conditions to grow jack beans (Canavalia ensiformis) that in turn rhizo-and phytoremediated residual aliphatic and aromatic hydrocarbons in the soil. Landfarming oily sludge adequately reduced jack bean phytotoxicity. Rhizo-and phytodegradation reduced total petroleum hydrocarbons by 57.38 % during 4 months of growing jack beans. Aliphatic hydrocarbons were detected in the roots but not in the aerial parts. Polycyclic aromatic hydrocarbons were translocated to the roots, stems, leaves, and beans, requiring successive cropping to manage all risks associated with some aromatic hydrocarbons found such as: acenaphthylene, anthracene, pyrene, benzo(a)anthracene, benzo(k)fluoranthene, and benzo(a)-pyrene. Landfarming and phytoremediation, perhaps with successive crops, holds the promise of providing inexpensive management of extensive oily wastes when sufficient land is available.

“…Iron can also be toxic when it accumulates to inappropriately high levels because free iron can participate in the Fenton reaction and generate cytotoxic hydroxyl radicals (Halliwell, and Gutteridge, 1992). Metals are non-biodegradable and persistent in the environment and can be differentially toxic to microbes (e.g., Giller et al, 2009), plants (e.g., Bharti and Singh, 2003;Singh et al, 2003Singh et al, , 2007Leon et al, 2006;Bauddh and Singh, 2009;Sharma et al, 2010), animals (e.g., Rainbow, 2006) and human beings (e.g., Lim and Schoenung, 2010).…”

Experiments were conducted to evaluate the plant tolerance to Fe and its phytotranslocation by Jatropha curcas L. from an iron rich wasteland soil. The soil was collected from wasteland soil (WLS) of a small town Sandila, (Hardoi, U.P.) India, and three Jatropha clones were cultivated in WLS amended or not with sand or cowdung in a ratio of 3:2. The WLS had high pH, elevated electric conductivity (EC) and was rich in organic carbon and total NPK. Iron and Mn were 2-3 folds higher than that in the normal field soil. Net root and shoot elongation as well as fresh and dry biomass of the plants were only slightly affected at 100 d in WLS as compared with that grown in non-polluted soil. Tolerance index (TI) of J. curcas was significantly higher in cowdung amended WLS in comparison to that in WLS, or WLS amended with sand. Translocation factor (TF) from the soil to plants for Fe was significantly higher in WLS than that in the normal field soil. Bio-concentration factor (BCF) and concentration index (CI) for Fe were 0.12 to 0.37, 1.0 to 6.2 respectively. The results indicate that Jatropha plantation is suitable for phytoremediation of Fe-contaminate wasteland soils, and also that these polluted fields could be used to cultivate this important biodiesel plant species.
