Abstract: Eucalyptus urophylla MLA clone (MLA) was difficult-to-root species. Eucalyptus urophylla U6 clone (U6) and Eucalyptus ABL. 12 W5 clone (W5) were relatively easy-to-root species.The activities of polyphenol oxidase (PPO) in MLA is lower than that of U6 and W5,but the activity of indoleacetic acid oxidase (IAAO) in MLA was higher than that of U6 and W5.The activities of PPO and IAAO and the isoenzymes of PPO in every species had their specificity in every organ.The relationship between the formation and development of adventitious roots and PPO and IAAO was discussed.
