Metal toxicity is an important factor governing germination and growth of plants. We have investigated how Co2+and Ni2+treatment affected germination and early growth stage of oilseed rape (Brassica napusL.). The results showed that the single pollution of Co2+was capable to stimulate the seed germination and seedling growth of oilseed rape at lower concentration, but the phenomena did not exist by the single pollution of Ni2+. Not only polluted by Co2+ but also by Ni2+, all indexes of germination and growth reduced gradually at higher concentration among examined concentration of heavy metals. Meanwhile, effects of Ni2+single pollution were stronger than that of Co2+single pollution.
