英文摘要 | Broad beans (Vicia faba) could tolerate up to 10% (w/w) crude oil in desert soil (sand), therefore, the potential of this crop for cleaning oily desert soil via rhizosphere technology was investigated. The amounts of hydrocarbons recovered from oily desert soil samples supporting V. faba plants were less than the amounts extracted from uncultivated oily soil samples. Excised fresh V. faba roots with their intact rhizospheres resulted in the attenuation of n-octadecane, phenanthrene, and crude oil when shaken into sterile desert soil extract containing these hydrocarbons. The amounts of hydrocarbons eliminated were greater with roots of plants previously raised in oily soil than with roots of plants raised in clean soil. Similar hydrocarbon attenuation effects were recorded when, instead of excised roots, whole plants were used with their roots submerged in the hydrocarbon containing soil extract. The various parts of plants raised in oily desert soil contained more linolenic acid in their total lipids than did the same parts of plants raised in clean desert soil. This was much more pronounced for the roots than for shoots and seeds. The hydrocarbons of roots and shoots of V. faba plants were not as affected by oil pollution as were those of seeds, in which the proportions of very long chain hydrocarbons increased with increasing oil concentration in the soil. Those hydrocarbons are not recommended for human and animal nutrition. |
