Uso de enraizadores na propagação do eucalipto arco-íris (Eucalyptus Deglupta Blume)

Abstract

The genus Eucalyptus is relevant due to its versatility and therapeutic properties, in addition to the economic relevance in cultivation for wood production. Vegetative propagation has been used to rescue trees with interesting phenotypic characteristics like this, and the use of rooters drives root formation for propagation. In view of the above, the present work was carried out with the objective of evaluating the vegetative propagation of cuttings with the use of different types of rooters in the production of seedlings by herbaceous and semilenhosa cuttings of rainbow eucalyptus (Eucalyptus deglupta Blume). The experiment was carried out at the Federal University of Ceará, and the collection of the material was carried out in a production area of Agriculture Sector II and the evaluations in greenhouse 06, agriculture sector I, belonging to the Department of Phytotechnics of the Federal University of Ceará, at the Pici Campus, in Fortaleza-CE. Eucalyptus cuttings were harvested and separated into herbaceous and semilenhoso material, cuttings previously passed by fungicide and bactericidal processes. Then, the cuttings underwent treatment with four rooters, applied at the base of the cuttings, these being the Saddle Gel®️, Forth Rooting, Power Rooting®️, cinnamon powder and a control treatment. The piles were placed in pots with wire frames and plastic bags for the formation of a stucco and the vessels were placed in trays. At the end of 36 days, the cuttings were washed and the rooting, length, diameter and number of roots and number of leaves were evaluated. The data were submitted to a descriptive analysis, observing the mean values.
