“…Maximum absorbance of reagent ascorbic acid is at 265 nm and that of the purified elution sample is 260 nm. The material in peak 5 appears to be implicated in the regulation of radicle growth in the developing soybean seed and in 2,4-dichlorophenoxyacetic acid-treated soybean seedlings (Key and Galitz 1959).…”

Perchloric acid extracts of soybean seeds were separated by column chromatography into 17 peaks. Thirteen nucleotides were identified in 11 of these peaks (NAD, CMP, CDP, CTP, AMP, ADP, ATP, CMP, GDP, GTP, UMP, UDP, and UTP). Two of the peaks were identified as ascorbic acid and dehydroascorhic acid. Four peaks remain unidentified although one of these appears to he protein.Monophosphates decreased and triphosphates increased as development proceeded. Diphosphates were initially low and showed no statistically significant difference with maturity.The accumulation of triphosphates in late stages of development is discussed in relation to synthetic activities of the developing seeds.

“…In earlier experiments indications were obtained that 2,4-D induces the formation of a secretable growth inhibitor in the roots of pea seedlings (Eliasson 1959). Key and Galitz (1959) showed that 2,4-D increases the content of an inhibitor in soybean.…”

Effect of Light on the Response of Pea Seedling Roots to 2,4‐Dichlorophenoxyacetic Acid

White light increases the inhibition of growth in length of pea seedling roots caused by 2,4‐D. This effect is most pronounced in the case of lateral root growth. The effect is obtained also if the shoots above the cotyledons are removed and is probably due to the direct influence of light on the roots. While light also weakly enhances the inhibition of pea root growth caused by 1‐naphthylacetic acid, light does not increase the sensitivity of wheat roots to 2,4‐D or naphthylacetic acid.
