The effects of lead salts (chloride, nitrate, acetate) on the elongation growth of three cereal species (maize, wheat, rye) under the same growth conditions were studied. It has been found that the most toxic lead compound for maize was acetate, while the most sensitive to lead chloride was wheat. It is suggested that in order to obtain comparable results in experiments on the effects of different heavy metals on plant growth, the same salts of metals should be used.
