Immature seeds of pea and barley were harvested on plants grown in solutions containing 36 Cl − , 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 Cl − . 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.
