Abstract

Eucalyptus urophylla Blade MLA clone (MLA) is a species that is difficult to root and E. urophylla Blade U6 clone (U6) and E.ABL 12 W5 clone (W5) are two species that are easy to root. The activity of indoleacetic acid oxidase (IAAO) in MLA was higher than that in U6 and W5. After treated with naphthylacetic acid (NAA), the activities of IAAO varied and the contents of soluble protein increased regularly at different stages of rooting of Eucalyptus cuttings. The relationship between IAAO and rooting of Eucalyptus cuttings was also discussed.
