Plant chemical priming by humic acids
WebSep 14, 2024 · Humic acid (HA) is composed of a complex supramolecular association and is produced by humification of organic matters in soil environments. WebThe content of auxin-, inhibitors-and gibberellin-like substances in freeze-dried humic acids was studied. The results indicate the existence of growth-promoting substances in humic acids, possibly corresponding to IAA or its precursors. Inhibitory activity is more marked during germination than during the growth process.
