[en] The endogenous auxin content of poplar shoots raised in vitro increased from the 3rd hour until the 7th hour under rooting conditions. At the 6th hour, the cytokinin content in the shoots on the rooting medium was lower than in control plants. These results show that at the end of the induction phase (previously described as a 7 hour period) the auxin/cytokinin ratio is very high. The variation of endogenous abscisic acid was not specific for rooting as its evolution is very similar for plants grown on rooting and on control media.
