“…In their experiment Trifolium album, Vicia sativa, Medicago luplina and Trifolium pratense in 25 g/kg of contaminated soil showed seed germination nearly equal to control with no fuel oil. Another study Huang, et al, (2004) demonstrated that the germination frequencies of the grass species were all affected by creosote in a concentration dependent manner. Germination of Festuca arundinacea was not affected by 1 g/kg creosote in soil but Poa pratensis was able to germinate about 80%.…”

“…Various petroleum products are common soil contaminants and often contain potentially hazardous chemicals, particularly the polycyclic aromatic hydrocarbons (Huang, et al 2004). The accumulations of PAHs in soil are due to many anthropogenic sources such as coking plants, solid fuel domestic heating, aircraft exhaust, car exhausts and forest fires (Smith, et al 2006).…”

ABSTRACT:Effects of contaminated soil with spent oil on germination, above ground height and biomass of six herbaceous plant species were investigated by conducting a general phytotoxicity test and growth inhibition assessment. Six local plant species were used in order to investigate plant's ability to germinate and survive in a gradient of contaminated soil with spent oil. The species selected for this experiment include one species of Fabaceae (Medicago truncatular), four species of Gramineae (Bromous mermis, Secal seral, Triticum sativa and Agropyron deserterum) and one species of Linaceae (Linum ussitasimum). Inhibitory effect of contaminated soil on germination, height of young seedling and dry weight were measured. In this study an artificial soil with a light texture included 85% sand, 10% silt and 5% clay was used. The exposure to the contaminated soil carried out using four consecutive concentrations (25, 50, 75, 100 g/kg). Results obtained from the current investigation indicate that all species perform dose-dependent responses to the contaminated soils. Reduction in germination, above ground height and biomass for all species were significantly (P < 0.05) different when compared to their controls, however, Medicago truncatular performed the highest and Linum ussitatisimum the lowest inhibitory effect for germination, above ground height and dry weight of seedling.

“…Although PGPR was first used for prompting the plant growth and for the biocontrol of plant diseases, much attention has recently been paid on bioremediation with PGPR (Huang et al, 2004b(Huang et al, , 2005Narasimhan et al, 2003). In contrast with inorganic compounds, microorganisms can degrade and even mineralize organic compounds in association with plants (Saleh et al, 2004).…”

“…Compared with physical and chemical remediation, phytoremediation has several advantages: (1) it preserves the natural properties of soil; (2) it acquires energy mainly from sunlight; (3) high levels of microbial biomass in the rhizosphere can be achieved; (4) it is low in cost; and (5) it has the potential to be rapid (Huang et al, 2004b). Although with these advantages, some plants show very low tolerance to the soil contaminants, which limits the degradation efficiency to an insufficient level for the meaningful soil remediation.…”

“…However exogenous factors such as water,  2016, ALÖKI Kft., Budapest, Hungary salinity, nutrients or the presence of toxic metals have a considerable impact on the final root structure (Arduini et al, 1994). Many plant species are sensitive to petroleum contaminants (Huang et al, 2004). Hydrocarbons in the soil may prevent uptake of nutrients that are less mobile in contaminated soils (Atuanya, 1987 There was no significant difference in the dry weight of total roots (primary and lateral roots).…”

Abstract. Exposure to persistent organic hydrocarbon pollutants can have deleterious effects on the growth, physiology and anatomy of plants. Sand collected at an oil-drilling quagmire in southern Algeria was analyzed by GC-FID and found to contain 18mg.Kg -1 hydrocarbons. Pisum sativum L. (pea) plants were grown in laboratory conditions in sandy soil from the site. Plants growing in hydrocarbon polluted sandy soil had shorter primary roots and fewer lateral roots than control plants growing in non-polluted sandy soil. However lateral root dry weight was 35% higher than control. Pollutant-induced oxidative stress on pea roots resulted in lipid peroxidation and accumulation of MDA, H 2 O 2 and O 2 -in root tips. Enzymatic detox activities of superoxide dismutase and peroxidase were also over 40% higher in plants growing on polluted soil than in controls. The anatomy of pea roots was also affected by hydrocarbonpolluted soil, because xylem vessel differentiation was delayed and an unusual supplementary cell layer was formed in the endoderm. These data suggest pea plants adapt morphologically and anatomically to polluted soil.
