???metadata.dc.description.resumo???: Objetivou-se, com este estudo, avaliar a eficiência dos antioxidantes ácido ascórbico e polivinilpirrolidona (PVP) no enraizamento de miniestacas de três clones de Eucalyptus urophylla x Eucalyptus grandis. As miniestacas foram coletadas em minijardim clonal, conduzido em canaletas de alvenaria preenchidas com areia lavada. Experimentalmente, foram testadas cinco concentrações de cada antioxidante nos três clones estudados (C1, C2 e C3). Foram realizadas avaliações de sobrevivência e enraizamento de miniestacas na saída das casas de vegetação e de sombra e da sobrevivência e crescimento das mudas aos 50 dias de idade. A utilização do ácido ascórbico foi favorável para as miniestacas do clone com menor porcentual de enraizamento (C3), porém, a utilização do PVP mostrou-se desfavorável para os clones estudados.

Description: The objective of this study is to evaluate the effectiveness of the antioxidants ascorbic acid and polyvinylpyrrolidone (PVP) in the rooting of mini-cuttings for three clones of Eucalyptus urophylla x Eucalyptus grandis. Mini-cuttings were gathered from a mini-clonal hedge which had been cultivated in concrete ducts containing washed sand. Five concentrations of each antioxidant were experimentally tested on each of the three clones (C1, C2 and C3). Assessments were done of mini-cutting survival and rooting rates when leaving the greenhouse and the shade house, as well as seedling survival and growth at age 50 days. Ascorbic acid was found to be beneficial to the mini-cuttings of the clone with a lower rooting percentage (C3), whereas PVP was found to be unbeneficial to the clones being studied.
