Abstract: Root-cut seedling of Acacia mearnsii were inoculated with Agr-obactfrium rhizogences A4, 9402, and rooting was promoted on MS medium. The rooting ratio was 96%~98%, and the average number of new roots per seedling was 17~19, but the root-cut seedling treated with medium alone didn't root. Opine assay indicated that there was stable maintenance of T-DNA in these new roots. There was some relationship between auxin and A. rhizogencs T-DNA in the induction of rooting.
