“…In this study, climatic factors were probably decisive since the production of cuttings was favored by the increase in temperature. This same behavior was also observed for Eucalyptus dunnii (Rosa et al, 2009), Sapium glandulatum (Ferreira et al, 2010), Piptocarpha angustifolia (Ferriani et al, 2011), clones of Eucalyptus benthamii × Eucalyptus dunnii (Brondani et al, 2012) and Eugenia uniflora (Peña Peña et al, 2015).…”

“…This effect was attributed to several factors, among them juvenile propagules, physiological conditions, hormonal balance and nutritional conditions throughout the sprout collection periods. This species presented adaptability to different climatic conditions (Peña Peña et al, 2015). However, for Psidium guineense, P. cattleyanum and P. guajava, the percentage of rooted minicuttings was not influenced by collection seasons, and presented 95.8%, 91.6% and 100% of rooting, respectively (Altoé et al, 2011).…”

The objective of this work is to evaluate the effects of nitrogen doses on the ministrain of C. aurea conducted in minigarden system regarding productivity, rooting and root system quality of minicuttings at different seasons. The experiment was conducted at a greenhouse, and the treatments consisted of collection times (autumn, winter, spring and summer) and nitrogen doses (0, 0.3, 1.12, 1.95 and 3.60 g L -1 ). We evaluated the survival of ministrains, productivity of minicuttings, percentage of rooting and root dry matter. The experiment comprised randomized blocks in a 5 x 4 factorial design. Data were subjected to analysis of variance and polynomial regression, and means were compared by Tukey test at 5%. The mean productivity was 10.0 and 18.9 minicuttings per ministrain in the spring and summer, respectively. Rooting was hindered by the increase in nitrogen doses. We concluded that the survival of ministrains is influenced by nitrogen fertilization, and that the N dose 1.12 g L -1 provides better results for productivity and rooting of minicuttings when collected during the spring and summer.Adubação nitrogenada em minicepas de Campomanesia aurea O. Berg e sua influência na produtividade e enraizamento de miniestacas em diferentes estações do ano RESUMO: O objetivo deste trabalho foi avaliar o efeito de doses de nitrogênio em minicepas de C. aurea conduzidas em sistema de minijardim sobre a produtividade, enraizamento e qualidade do sistema radicular de miniestacas em diferentes estações do ano. O experimento foi conduzido em casa de vegetação e os tratamentos consistiram em épocas de coleta (outono, inverno, primavera e verão) e doses de nitrogênio (0, 0,3, 1,12, 1,95 e 3,60 g L -1 ). Avaliou-se a sobrevivência das minicepas, a produtividade de miniestacas, porcentagem de enraizamento e matéria seca de raiz. O delineamento experimental foi em blocos casualizados em arranjo fatorial 5 x 4. Os dados foram submetidos à análise de variância regressão polinomial e teste de Tukey a 5% de probabilidade de erro. A produtividade média foi de 10,0 e 18,9 miniestacas por minicepa na primavera e verão, respectivamente. O enraizamento foi prejudicado pelo aumento das doses de nitrogênio. Conclui-se que, a sobrevivência de minicepas é influenciada pela aplicação de adubação nitrogenada, e que a dose de 1,12 g L -1 de nitrogênio apresenta resultados superiores na produtividade e enraizamento de miniestacas quando coletadas na primavera e verão.

“…The system most applied in forest species has been the denominated semihydroponic, composed of a channel containing inert substrate (sand) to support the mini-stumps (Wendling et al, 2007;Xavier & Silva, 2010). However, in native species, the establishment of mini-clonal hedges in pots, tubes, or polyethylene boxes has been tested frequently (Xavier et al, 2003a(Xavier et al, , 2003bPeña Peña et al, 2015;Peña, 2015). Considering that plant nutritional management is limited to the area available for root development, the greatest difference between these two systems lies in the productive capacity and vigor of the propagules.…”

Understanding the mechanisms involved in tree species maturation, related mainly to ontogenetic age effects, has contributed significantly to the vegetative propagation process of Brazilian native tree species, with consequent application of clonal forestry. A number of methodologies has been developed to rescue and vegetatively propagate these species for silvicultural and environmental restoration purposes. However, the types and purposes of propagation, as well as the choice of suitable processes and propagules considering the intended objectives, still need to be better aligned. In addition, there is an evident knowledge gap and great potential regarding the use of native tree species in Brazilian clonal forestry, indicating the need of a greater interaction between studies on the vegetative propagation and vigor of these materials in the field. Therefore, this review aims to help understand the different types of techniques used and their application on the vegetative propagation and clonal forestry of Brazilian native tree species, besides proposing a schematic sequence of the stages involved in these processes for productive and environmental purposes.

“…Algumas espécies como Pinus taeda, Eucalyptus benthamii × Eucalyptus dunnii, Araucaria angustifolia e Drymis brasiliensis apresentaram maiores percentagens de enraizamento de miniestacas no inverno (Alcantara et al, 2007;Brondani et al, 2010) e em Piptocarpha angustifolia além do inverno, a primavera também foi uma estação favorável ao enraizamento de miniestacas (Ferriani et al, 2011). No entanto, o verão e a primavera foram as melhores épocas do ano para coleta e enraizamento de miniestacas de Pinus taeda (Alcantara et al, 2008) e todas as estações do ano, com exceção do outono, foram favoráveis ao enraizamento de miniestacas de Eugenia uniflora (Peña et al, 2015).…”

RESUMO:O objetivo deste trabalho foi estudar o efeito de época de coleta no enraizamento de miniestacas para desenvolver uma estratégia de seleção que maximize o ganho genético e facilite a identificação de clones de canjerana com potencial para a propagação vegetativa. Um minijardim clonal foi estabelecido com 22 clones de canjerana, no qual realizaram-se coletas de miniestacas em três épocas durante o período de maior crescimento vegetativo. Foram avaliadas as percentagens de sobrevivência, enraizamento e brotação de miniestacas, o número e comprimento de raízes e brotos e o número de miniestacas enraizadas por minicepa. Os clones foram agrupados pelo método não-hierárquico das k-médias para o número de miniestacas enraizadas em cada época de coleta. A identificação dos melhores clones foi realizada com base na soma de postos e estimado o ganho genético de seleção. A época de coleta das brotações afeta o enraizamento de miniestacas de canjerana. A seleção de clones de canjerana deve ser realizada com base no número de miniestacas enraizadas por minicepa durante todo o período de crescimento vegetativo.Palavras-chave: Cabralea canjerana; ganho genético; miniestaquia; sazonalidade Rooting of mini-cuttings in different collection times for the selection of canjerana clonesABSTRACT: The objective of this work was to study the effect of the collection time in rooting capability of mini-cuttings to develop a selection strategy to maximize genetic gain from selection and to facilitate the identification of canjerana clones with potential for vegetative propagation. A clonal mini-hedge was established with 22 canjerana clones and mini-cuttings were collected in three different times during the vegetative growth season. The percentages of survival, rooting and shooting, the number and length of roots and shoots and the number of rooted mini-cuttings per mini-stump were evaluated. The clones were clustered by the nonhierarchical k-means method for the number of rooted mini-cuttings in each collection time. Clone selection was based upon the sum of ranks and genetic gain from selection was estimated. The collection time of canjerana shoots affects the rooting capability of mini-cuttings. Selection of canjerana clones should be based upon the number of rooted mini-cuttings per mini-stump, during the whole season of vegetative growth.
