METHANOL extracts of immature seeds of Pisum sativum exhibited fairly strong auxin-like activity when assayed by hypocotyl swelling of Phaseolus mungo1. We isolated an active principle from the neutral fraction of immature seeds2; it was identified as methyl 4-chloroindolyl-3-acetate by synthesis. Preliminary examination showed that its auxin activity against Avena first internode and section tests was comparable with that of methyl indolyl-3-acetate while its activity was stronger against the… CONTINUE READING
