Abstract
The Effects of Gas Oil on Germination and Seedling Development of Some Crop SpeciesZahedeh Chaghari M. Sc.

Student in Plant Biotechnology and Phsiology, Faculty of Biological Sciences, Shahid Beheshti University Gholamhossein Ebrahimipour, Ph.D. Assistant Professor, Faculty of Biological Sciences, Shahid Beheshti University Hossein Shaker-Bazarnov, Ph.D. Assistant Professor, Faculty of Biological Sciences, Shahid Beheshti University Françoise Bernard, Ph. D. Associate Professor, Faculty of Biological Sciences, Shahid Beheshti University Abstract The aim of the study was to determine the effect of soil contamination with gas oil (4.5 g/kg soil) on the germination in Trifolium repens L., Triticum lontherium L., Hordeum vulgaris L., Medicago sativa L., Carthamus tintoriusL. and Zea mays L. Delayed seed emergence and reduced percentage germination was observed for the majority of plant species. Germination in M.sativa and T. lontheriumhad reduced significantly after 4 weeks. Fresh weight of root and shoot also reduced for all speices; but dry weight in shoot and root in Z.mays and C. tintorius increased. In other hand was the effects of high soil contamination were investigated on Maize and safflower (9, 13.5 and 22 g/kg soil). In two recent species significantly reduction in fresh weight of shoot and root was observed in 9, 13.5 g/kg soil, dry weight of shoot and root increased in Z. mays, although this increased happened only for root of C. tintorius.
