Degradation of indole-3-aeetie acid was investigated in etiolated pea shoots; the study was limited to indolic metabolites. The products formed were fractionated by column chromatography and identified by thin-layer chromatography and chemical methods. The pathway of indole-3-acetic acid degradation
Indole-3 acetic acid (IAA) strongly enhanced rooting ofeh ~lated pea epicotyl cuttings while gibberellic acid (GA3) enhanced rooting only slightly. The promoting effects of the hormones appeared not until 14 d after the onset of treatment. When GA~ and IAA were applied together, the initiation of ro
