Changes Germination, Growth and Anatomy Vicia Ervilia in Response To Light Crude Oil Stress

Thepetroleum concentrations are contaminant important sources in the environment. hydrocarbon’s contaminants depend on their type and concentration can cause variable toxicity in soils, on the other hand, different kinds of plants also response concentration of contaminant differently, because of the diversity of physiological and morphological characteristics. in this study the effect of different concentrations of light crude oil was investigated on stem length, germination and anatomical of vicia ervilia. a factorial experiment was used with a randomized complete block design (rcbd) with three replications. the results showed that the germination and stem lengths decreased significantly (p≤ 0.05) with increasing concentrations of petroleum. anatomical studies the changes of parenchyma, vascular bundles, epidermal and increase crack showed.
