Abstrakt		The amount and composition of auxins were investigated in bean seedlings (Phaseolus vulgaris L.) cv. Zorin. Extracts of cotyledon, leaves, stems with shoots and roots were purified with Sep-Pak C18 cartridges and analysed by HPLC with fiuorescent and photodiode array detectors. Biological activity was determined with an Avena bioassay. The highest amount of indole-3-acetic acid (IAA) was detected in roots. In all analysed tissues bound IAA predominated. HPLC and bioassay confirmed IAA conjugates after hydrolysis with 7 N NaOH. In been seedlings, in addition to free IAA, some conjugates also showed biological activity.
