Marquis wheat treated with a series of talc dusts containing indolylacetic acid, potassium naphthylacetate, potassium nitrate, and ethyl mercuric bromide was grown in soil in the greenhouse. Potassium naphthylacetate increased the final germination count 2.6% while indolylacetic treatments failed to affect germination or early growth. Neither of these growth stimulating chemicals interacted with potassium nitrate or ethyl mercuric bromide. Ethyl mercuric bromide retarded the germination rate but increased the final germination count. Potassium nitrate in conjunction with the organic mercurial disinfectant reduced final germination and the air-dry weight of young plants. On the average, dust treatments reduced the rate of germination but increased the air-dry weight of stems.
