Abstract/Contents:"Twenty-five pots (five 28-day-old seedlings per pot) were flooded with .005 gm. of the sodium salt of 2,4-dichlorophenoxyacetic acid in 30 ml. of water (per 190 gms. of moist soil). Ten days after the time of treatment, increased growth at the base of the plant had caused some of the leaves to bend unnaturally. The plants resembled young onions. A large number of small protuberances had appeared on many of the primary roots. The treated plants had much smaller root systems than those that remained untreated. Permanent microscope preparations showed that about 5 mm. above the solid stem at the base of the plant leaves from treated plants were seriously injured. After ten days the veins had been pushed out of position by typical chloroplast-free replacement cells. The swollen base of the plant contained many root initials, the development of which had been stimulated by the chemical. Root initials had been increased in number along the primary root, but then elongation had been inhibited, reducing the over-all size of the root system. (With seven illustrations.)"
