Abstract

The cuttings from some old Eucalyptus trees have inferior ability to root, leading to difficulties to multiply plus or elite clones from them. The main cause for this phenomenon is attributed to polyphenols contained in those trees. In the present study, polyphenols contained in E. camaldulensis cuttings or dissolved in water after scission of the cutting shoots were identified and quantified to clarify the effects of polyphenols on rooting. In addition, assays of polyphenol oxidases from the cuttings were also tried to examine the involvement of the enzymes in rooting.
