The ecotoxicological effects of Cr2+ on germination and early seedling growth of six pulses were investigated. Seeds of these plants were exposed to seven different concentrations of Cr (0-3.2 mM). The results indicated that root elongation and coleoptile growth of six pulse plants were more sensitive than seed germination for measurement of the toxic of Cr2+ pollutions. Different species show different levels of tolerance to Cr2+ pollution.
