Growth-Controlling Effects of some Quaternary Ammonium Compounds on Various Species of Plants
1953
1. A quaternary ammonium compound, (4-hydroxy-5-isopropyl-2-methylphenyl)trimethylammonium chloride, 1-piperidine carboxylate, designated Amo-1618, was applied to soil in which bean seeds (Phaseolus vulgaris, variety Black Valentine) were planted. It was absorbed by the roots of seedlings and apparently translocated to the stems, leaves; and seeds. 2. Amo-1618 induced the plants to develop relatively short internodes, thick stems, and dark green leaves in comparison with untreated plants. Maturity was delayed. When the chemical was applied at rates of 1, 10, and 100 pounds per acre, the intensity of these responses was in proportion to the amount of chemical used. 3. The effect of Amo-1618 applied at the rates of 10 or 100 lb/A persisted in the soil apparently undiminished during a period of 3 years. At the rate of 1 pound per acre the effect of the chemical was diminished but was still apparent at the end of 3 years. 4. The effects of Amo-1618 absorbed from the soil and translocated to the seeds were evi...
