-Agroforestry systems with eucalyptus prevail in Central and Southeast Brazil, and little information is available about systems using native trees. The aim of the present study was to evaluate the development of seven native tree species grown under two agroforestry systems. The experiment was conducted starting in 2007 in 12-hectare area in the municipality of São Carlos, São Paulo state, Brazil. The tree species planted in the two systems (a silvopastoral system and an agrisilvicultural system) were: 'capixingui' (Croton floribundus) and 'mutambo' (Guazuma ulmifolia) (tutors), 'jequitibá-branco' (Cariniana estrellensis), 'canafistula' (Peltophorum dubium) and 'ipê felpudo' (Zeyheria tuberculosa) (timber trees), and 'angico-branco' (Anadenanthera colubrina) and 'pau-jacaré' (Piptadenia gonoacantha) (N-fixing trees). Data were collected for 48 months. The results show differences among tree development, which was evaluated as growth in height and diameter, as well as sensitivity to insect and disease damage. The overall results show that the agrisilvicultural system allowed better tree development. The species with best performance in the two systems were capixingui, mutambo and canafístula. Ipê-felpudo and jequitibá-branco showed the worst results. The high variability among individuals of the same species indicates the possibility of high production advances with selective breeding of these species.Keywords: Agroforestry; Production systems; Tropical semideciduous forest. DESENVOLVIMENTO DE ESPÉCIES FLORESTAIS NATIVAS EM DOIS SISTEMAS AGROFLORESTAISRESUMO -Sistemas de produção arborizados com eucalipto predominam no Centro e Sudeste do Brasil, com poucos dados sobre o desempenho de espécies florestais nativas nesses sistemas. O objetivo deste trabalho foi avaliar o desenvolvimento de sete espécies florestais nativas em dois tipos de sistemas de consórcio agroflorestal. O experimento foi implantado em 2007 em uma área de 12 ha, no município de São Carlos -SP. Foram plantados: capixingui (Croton floribundus) e mutambo (Guazuma ulmifolia) (tutoras); jequitibá-branco (Cariniana estrellensis), canafistula (Peltophorum dubium) e ipê-felpudo (Zeyheria tuberculosa) (madeireiras); e angicobranco (Anadenanthera colubrina) e pau-jacaré (Piptadenia gonoacantha) (fixadoras de nitrogênio) em dois tipos de sistemas de consórcio, representados por um sistema silvipastoril e um sistema silviagrícola. Os dados foram coletados durante o período de 48 meses. Houve diferença no desenvolvimento das árvores, avaliados por altura, diâmetro de coleto, danos por insetos e por doenças. O sistema silviagrícola propiciou maior desenvolvimento das árvores. As espécies que se destacaram, nos dois sistemas, foram capixingui, mutambo e canafístula. O ipê-felpudo e o jequitibá-branco apresentaram os piores desempenhos. A grande variabilidade apresentada entre os indivíduos indica a possibilidade de ganhos produtivos significativos com trabalhos de melhoramento e seleção dessas espécies.Palavras-chave: Floresta Estacional Semidecídua;...

“…Brachiaria and other invasive fodder grasses have been considered one of the most important biological barriers to restoring tropical forests worldwide (García-Orth and Martínez-Ramos, 2011;Ortega-Pieck et al, 2011, and references therein), and their effective control is essential to support the fast development of the forest under restoration (Campoe et al, 2010). As a result, we may have a trade-off between the use of alternative methods of grass control and the development of the forest community under restoration.…”

“…Of these barriers, the dominance of exotic fodder grasses is considered a critical ecological barrier to the restoration of tropical forest (García-Orth and Martínez-Ramos, 2011;Ortega-Pieck et al, 2011), by blocking seeds from reaching the soil and competing with young trees (Aide et al, 1995;Campoe et al, 2010Hooper et al, 2005. Therefore, the control of such grasses is crucial for the success of restoration projects around the world.…”

Alternative methods to control invasive fodder grasses are necessary to reduce the use of herbicides in forest restoration, which has been carried out primarily in riparian zones.We sought to investigate if inter-row cultivation of crotalaria (Crotalaria breviflora DC) or pumpkin (Cucurbita moschata Duschene ex. Poir) with native tree species is an efficient strategy to control invasive fodder grasses in restoration plantings. We tested five treatments in a randomized block design, namely (1) control of brachiaria grass (Urochloa decumbens (Stapf.) Webster) with glyphosate in the implementation and post-planting grass control of the reforestation, (2 and 3) glyphosate use in the implementation and inter-row sowing of crotalaria (2) or pumpkin (3), and control of brachiaria by mowing in the post-planting phase, (4 and 5) mowing in the implementation and inter-row sowing of crotalaria (4) or pumpkin (5), and control of brachiaria by mowing in the post-planting phase. Post-planting grass control was carried out four and nine months after tree seedling planting. Throughout 13 months, we evaluated the percentage of ground cover by brachiaria grass, pumpkin production, and native tree seedling mortality, height and crown cover. The exclusive use of glyphosate, without inter-row sowing of pumpkin or crotalaria showed the most favorable results for controlling brachiaria grass and, consequently, for tree seedling development. Hence, inter-row cultivation of green manure or short-lived crop species is not enough to control invasive grasses in restoration plantings, and complementary weeding is necessary to reduce the highly competitive potential of C4 grasses for supporting native species seedlings growth.

“…This type of forest regeneration is used to produce forests for environment restoration (CAMPOE et al 2010;CAMPOE et al 2014), enrichment of natural forests (KETTLE 2009;NAVARRO-CERRILLO et al 2011;SCHWARTZ et al 2013) or to constitute highly productive monocultural plantations (DESROCHERS; TREMBLAY 2009). The costs of artificial regeneration are associated with site slope, access to site, human labor cost, seedling availability and the need for post-planting competition control (BIRCH et al 2010;CAMPOE et al 2010). Seedlings with high quality and fast initial growth decrease artificial regeneration costs by reducing competition control costs (MCNABB;SCHAAF 2005) and increase the financial yield from the forest by reducing the time span between planting and logging trees.…”

ABSTRACT:The success of forest creation relies on seedling availability and quality. The aim of this research is to assess the possible use of rootstock and bare-root seedlings of Cedrela fissilis obtained from natural regeneration for direct field planting. We used Generalized Linear models to assess survival and Hierarchical Models to assess height growth over one year after planting. Initial root-collar diameter (RCD) and treatment (rootstock or bare-root) affected survival and growth. Rootstock and larger seedlings presented higher levels of survival and growth. Higher seedling quality in the rootstock treatment is due to higher water stress tolerance. Rootstock seedlings with more than 1 cm of initial RCD had over 80% of survival probability, while small bare-root seedlings had mean survival probability as low as 20%. Rootstock seedlings grew as much as fourfold more than bare-root. Using natural regeneration of C. fissilis as a source of rootstock seedlings may be a cheap alternative for forest restoration and enrichment planting projects. UTILIZAÇÃO DE MUDAS DE RAIZ NUA E MUDAS DE TOCO PROVENIENTES DA REGENERAÇÃO NATURAL DE CEDRELA FISSILIS RESUMO:O sucesso da implantação de florestas depende da disponibilidade e da qualidade de mudas. O objetivo desta pesquisa é avaliar a possibilidade do uso de mudas de toco e mudas de raiz nua de Cedrela fissilis obtidas de regeneração natural para plantio à campo. Nós usamos Modelos Lineares Generalizados para avaliar sobrevivência e Modelos Hierárquicos para avaliar crescimento em altura durante um ano após o plantio. O diâmetro do colo (DC) inicial e tratamento (mudas de raiz nua ou de toco) afetaram a sobrevivência e o crescimento. Mudas de toco e mudas com maior DC inicial apresentaram maiores probabilidades de sobrevivência e maior crescimento. A melhor qualidade de mudas no tratamento de mudas de toco é devido à maior tolerância ao stress hídrico. Mudas de toco com DC inicial maior que 1 cm tiveram probabilidade de sobrevivência acima de 80%, enquanto mudas de raiz nua pequenas tiveram probabilidade de sobrevivência média de 20%. As mudas de toco cresceram quatro vezes mais que mudas de raiz nua. A utilização da regeneração natural de C. fissilis como fonte de mudas de toco pode ser uma alternativa barata para projetos de restauração florestal e plantios de enriquecimento.
