Dentre as técnicas de propagação vegetativa utilizadas no melhoramento genético florestal está a enxertia, qual é utilizada na multiplicação matrizes selecionadas, visando à produção sementes melhoradas. O estudo teve como objetivo avaliar três enxertia em Eucalyptus grandis. experimento foi conduzido delineamento inteiramente casualizado, analisando garfagem fenda cheia com alicate sob casca e canivete enxertia. A técnica apresentou pegamento 50%, sendo superior (33,3%) (33,3%). comprimento...
Background: Direct sowing technique is considered a promising tool for reducing costs and increasing species diversity in restoration projects. However, several factors can limit its success, making it necessary methodological adjustments to be made order maximize the emergence, establishment initial growth of plants. This study aimed evaluate influence use fungus Trichoderma asperelloides hydrogel enrichment direct as strategy enrich area process. The forest studied were Balfourodendron...
Background: The increase in agricultural production requires sustainable alternatives development for reusing the waste generated, such as bovine manure, to obtain ecological, environmental, and economic benefits. In addition, proper fertilization is one of main steps forest species seedlings. Thus, this study aimed characterize effect different substrates formulations based on manure types fertilizers quality C. montevidense seedlings verify if field confirms nurseries' responses....
Establishing native forest tree species in degraded areas is a considerable challenge for forestry. Adverse ecological filters can compromise the sustainability of ecosystems undergoing restoration. Therefore, objective present study was to verify effects three silvicultural practices on allocation aboveground biomass, nutrient content, and control invasive plants mixed plantation extreme south Atlantic Forest Biome. The experiment conducted an area belonging Quarta Colônia State Park. It...
The demand for seedlings of native tree species the restoration altered areas has increased considerably. Therefore, knowing strategies that favor quality seedling production in nursery, addition to survival, growth, and development field, is important. This study was evaluate survival initial growth Inga vera Will Schinus terebinthifolius Raddi, after 24 months planting, an anthropized area. experiment conducted using a factorial scheme (2 × 2), considering types containers used presence or...
Native tree species present different responses depending on their adaptability to varying degrees of sunlight. The objective this study was evaluate the growth Myrocarpus frondosus seedlings under shade conditions in a nursery. experimental design included randomized blocks factorial scheme, corresponding treatments full sun (0%), or one three shading intensities (30%, 50%, and 70%), with evaluation times 30, 90, 150, 210, 270, 330, 390 days after emergence – d.a.e. morphological attributes...
O objetivo foi identificar a influência do tipo de recipiente e da inoculação Trichoderma spp. sobre o crescimento inicial plantas Erythrina cristagalli. Testou-se dois tipos recipientes (tubetes polipropileno sacos polietileno) T. asperelloides, harzianum testemunha. Nove meses após plantio, determinou-se sobrevivência, altura diâmetro coleto. A sobrevivência das 89,65%. As mudas provenientes com maior volume apresentaram H DC. E. cristagalli é uma espécie que apresenta potencial para uso...
Corymbia citriodora and Eucalyptus dunnii are species of relevant importance due to the quality wood growth potential in Southern Brazil. Therefore, we aimed identify containers doses controlled-release fertilizer capable enhancing morphophysiological these nursery, aiming for proper management inputs. The seedlings were produced two volumes (50 e 110 cm³), filled with Sphagnum peat-based substrate, mixed different (CRF) NPK 15-09-12 (0, 3, 6, 9 12 g L-1 substrates). In addition,...
O objetivo da pesquisa, foi verificar a influência de diferentes incidências luminosas e lâminas irrigação, sobre o incremento em altura (H) diâmetro do coleto (DC) mudas Parapiptadenia rigida (Bentham) Brenan Enterolobium contortisiliquum (Vellozo) Morong. estudo ocorreu, no Laboratório Silvicultura Viveiro Florestal Universidade Federal Santa Maria. Os tratamentos foram T1: lâmina 3 mm luminosidade (LU) = 100% (413 μmol m-2 s-1); T2: LU 50% (214 T3: 6 T4: 50%. A utilização menor...
Na propagação vegetativa, a utilização de estufim sobre o minijardim clonal (MJC) é uma estratégia empregada em escala operacional viveiros florestais grande porte, produtores mudas clonais Eucalyptus no Brasil, e mais recentemente testada interior dos ambientes enraizamento. O objetivo desse estudo foi constatar influência do uso MJC, associado diferentes enraizamento, percentual sobrevivência (S%) enraizamento (E%) miniestacas dois clones benthamii Maiden. & Cambage (B1 B2), durante os...
