Aspects of the physiological and chemical control of adventitious root formation in Eucalyptus nitens (Deane & Maiden) Maiden

TL;DRAbstract

Eucalyptus nitens is an important species in plantation forests in Tasmania and is becoming important in other cool temperate regions of the world. Reliable initiation of roots in cuttings is needed, to enhance forest productivity through the establishment of clonal plantations. Adventitious root initiation is dependent on the re-polarisation of cells to form a new root meristem. Failure to initiate roots may be due to the inability of the plant to undergo re-polarisation of cells to form a new meristem. The research undertaken has been directed at the manipulation of some of the factors that are implicated in the establishment of cellular polarity in plants. Several new techniques for enhancing root initiation have been investigated and shown to promote root formation in cuttings of E. nitens. The principle conclusions of the research are outlined below. It was demonstrated that a high proportion of E. nitens seedlings have the ability to initiate adventitious roots in cu
