| Objetivou-se avaliar a indução de brotações epicórmicas em cepas e as técnicas de estaquia, miniestaquia e enxertia para a clonagem de Cupressus lusitanica. Para a estaquia, testaram-se concentrações de ácido indolbutirico e substratos em plantas de 5 e 10 anos de idade. Na miniestaquia, avaliou-se o tipo de propágulo. Na enxertia, utilizaram-se propágulos de árvores de 10 anos como enxertos para o primeiro subcultivo, sendo, a partir deste, coletadas as brotações para o segundo subcultivo. A espécie apresentou difícil enraizamento e a enxertia, o melhor resultado. A indução de brotações de cepas apresentou baixa viabilidade.doi: 10.4336/2010.pfb.30.62.161 |

| This study was conducted in one region of a Seasonal Semideciduous Forest located in Tapurah (Mato Grosso State, Brazil) with the aim of studying its floristic and structural composition. The fixed area method was applied to 10 × 250 m clusters, allocating and measuring five clusters with five subunits of 500 m² each. Species with a diameter at breast height greater than or equal to 10 cm were considered, and the sample sufficiency of the floristic survey was verified by a species accumulation curve. The similarities between the sample subunits were calculated by the Jaccard Similarity Index, and the species diversity with the Shannon Diversity Index and Pielou Evenness Index. The horizontal vegetation structure was characterized by density, frequency,... |

| There is little knowledge about the vegetative propagation of Ilex paraguariensis, mainly in relation to the minicutting technique and rooting environmental aspects. This study aimed to evaluate the initial rooting environment in relation to the survival, shoot vigor and minicuttings rooting of this species. The experiment was conducted in a completely randomized design, under a factorial arrange (3x2), with three clones (A7, A21 and A35) and two rooting environments (simple greenhouse - without control of temperature and humidity; and automatized greenhouse - with automatized control). The minicutting survival in the exit of greenhouses and in the exit of shadow house was not influenced by the tested environments, with 51.8 % to 71.9 % of... |

| The aim of this study was to evaluate the mini-stumps survival and the mini-cuttings production of Eucalyptus benthamii regarding to Zn and B concentrations during successive collection of shoots. Shoots were collected from mini-stumps (BP101, BP118 and BP120 clones) fertigated with nutrient solutions containing different concentrations of Zn and B (S1 – free of Zn and B, S2 – 0.5 mg L-1 Zn, S3 – 0.5 mg L-1 B, S4 – 0.5 mg L-1 Zn and B, S5 – 1.0 mg L-1 Zn and B, S6 – 2.0 mg L-1 Zn and B). Eight shoot collections of the clonal mini-garden were performed. The mini-stumps survival, mini-cuttings production, leaves number, nodes number, shoots length, internodes interval and visual appearance of mini-stumps to identify symptoms of nutritional deficiency or... |

| The aim of this study was to evaluate the foliar nutrient content in Eucalyptus benthamii mini-stumps treated with different Zn and B concentrations during successive shoot collections. Shoots were collected from mini-stumps fertigated with nutrient solutions containing different concentrations of Zn and B (S1 – free of Zn and B; S2 – 0.5 mg L-1 Zn; S3 – 0.5 mg L-1 B; S4 – 0.5 mg L-1 Zn and B; S5 – 1.0 mg L-1 Zn and B; S6 – 2.0 mg L-1 Zn and B). Eight shoot collections from the clonal mini-garden were performed. For each shoot collection, the nutritional content of the leaf was determined (N, P, K, Ca, Mg, S, B, Cu, Fe, Mn and Zn). The experiment was conducted using a randomized design with a factorial arrangement (8x6) and a split plot in time and... |

| The extrativism method, inappropriate management and the reduction of mate tree populations has resulted in the loss potencial of relevant specimens for future genetic improvement. Few are the techniques and studies, focused on the restoration of degraded mate tree plantations, in order to recover vegetative samples of mature trees. So, an experiment was installed in São Mateus Country, Paraná State-BR, in a mate weakened population whose trees aged approximately 40 years. The objective was to evaluate the efficiency of bark girdling, combined to different pruning intensities, on the sprouting at the base of the trunk of weakened mate trees. A bark ring of 1 cm width, at 20 cm from the base, was removed. Additionally the crown was submitted to three... |
