Methyl 4-Chloroindolyl-3-Acetate in Pea and Barley
Immature seeds of pea and barley were harvested on plants grown in solutions containing 36C1−, but no other chlorides. Autoradiography of two dimensional thin layer chromatograms (silicagel) of butanol extracts of freeze-dried seeds showed the presence in both species of several radioactive compounds besides C1−. One compound, present in pea and probably in barley, cochromatographed with a mixture of 4- and 6-chloroindolyl-3-acetic acid methyl esters. Another, detected in pea, but probably not in barley, cochromatographed with a mixture of 4- and 6-chloroindolyl-3-acetic acids.
