Previous issue date: 2016-07-01 / Conselho Nacional de Pesquisa e Desenvolvimento Científico e Tecnológico - CNPq / O tungue (Aleurites fordii) é uma planta da família Euphorbiaceae, adaptada ao
clima temperado, necessita cerca de 350 a 400 horas de frio (abaixo de 7,2°C) para
diferenciação de gemas vegetativas e floríferas. Essa espécie é cultivada com
objetivo de produzir óleo o qual tem uma característica muito importante que é
secagem rápida, sendo amplamente utilizado na indústria de tintas e resinas,
podendo também ser utilizado na ornamentação de vias e jardins. Mesmo a cultura
estando presente no Estado a mais de 50 anos, informações referentes ao
comportamento do tungue ainda são recentes. Assim, o objetivo do trabalho foi
avaliar a fenologia e determinar características agronômicas de interesse em clones
e genótipos de tungue no Rio Grande do Sul. As avaliações ocorreram em três
safras consecutivas avaliando-se as características morfológicas, fenológicas e
produtivas. Os resultados obtidos revelam variabilidade de interesse para as
características avaliadas. Foram identificados genótipos com alto potencial produtivo
e morfologia adequada para produção comercial e genótipos com potencial
paisagístico. Não houve diferenças entre os clones testados nos diferentes locais e
anos para as características morfológicas e fenológicas, entretanto houve interação
Clone x Local, existindo comportamento diferenciado dos clones, quanto a
produtividade, nos diferentes locais. / The tung tree (Aleurites fordii) plant belongs to the Euphorbiaceae family, adapted to
temperate climate, it needs about 350 to 400 chilling hours (below 7.2°C) for
vegetative and flower buds differentiation. This species is cultivated in order to
produce oil which has a very important feature that is quick drying and is widely used
in industrial paints and resins. It could also be used as an ornamental plant. Despite
being present in the State for over 50 years, information about the behavior of the
tung tree are recent. Therefore objective of this study was to evaluate the phenology
and determine agronomic traits of interest in clones and tung genotypes in Rio
Grande do Sul State. The morphological, phenological and productive characteristics
were evaluated in three consecutive harvests. The results showed variability of
interest to the characteristics evaluated. There were genotypes with high yield
potential and morphology suitable for commercial production and genotypes with
landscaping potential. There were no differences between the clones tested in
different locations and years for the morphological and phenological characteristics,
though there was interaction between clone x location. Clones showed different
behavior in different locations for productivity traits.The tung tree (Aleurites fordii) plant belongs to the Euphorbiaceae family, adapted to
