O uso de fertilizantes liberacao controlada constitui-se umas das formas suprimento ao longo da formacao mudas em viveiro. objetivo do estudo foi testar doses crescentes fertilizante (FLC) tubetes diferentes tamanhos no crescimento inicial Eucalyptus dunnii Maiden. As foram originadas sementes, semeadas 55cm³ e 110cm³, compondo o primeiro fator esquema fatorial 2 x 5. Ao substrato adicionadas FLC (0, 2, 4, 6 8 g L -1 ), segundo fator. Foi utilizado delineamento inteiramente casualizado com 4...
We analyzed the rooting of sequoia mini-cuttings from different clones in four seasons year and use logistic model to estimate time maximization each factor analysis. Mini-cuttings five grown clonal mini-garden were placed root mini-tunnel year. Weekly evaluations performed (from 30 93 days) these variables: survival (%), rooted (%) a number emitted roots. These data used adjust original function. The experiment was set completely randomized design, factorial scheme 5 (clones) x 4 (seasons),...
Sequoia sempervirens is different from other species not only for its excellent vigor and longevity, but also quality wood productivity. The objective of this work was to evaluate the rooting mini-cuttings in cultivation environments. In both experiments, evaluated time determine root development each environment. Mini-cuttings clone A228 clonal mini-garden were used. first experiment material placed take three environments: greenhouse (GH), shadehouse (SH) mini-tunnel, with evaluation...
Sequoia sempervirens is a fast-growing, long-lived tree with pest-resistant wood. The objective of this study was to quantify the adventitious rooting ability sequoia clones in two environments as well determining behavior during evaluation period. Mini-cuttings five grown clonal mini-garden were planted for different environments: mini-tunnel and an intermittently fogging greenhouse. Weekly assessments (from 30 93 days) variables performed: survival, rooted mini-cuttings number roots...
Ecological succession is one of the most important processes in forest ecosystems, still poorly understood highland Araucaria forests Southern Brazil. Here we investigated this process by describing functional composition changes response to a vegetation successional mosaic four fragments municipality Urubici, State Santa Catarina, Two were classified as advanced stage and two early stage. The following traits determined: wood density, leaf area, specific dispersal syndrome phenology. For...
O objetivo do estudo foi avaliar espécies e procedências de Eucalyptus spp., selecionando aquelas que apresentam elevada sobrevivência capacidade produtiva nas condições da região Planalto Norte
Sequoia sempervirens (D. Don) Endl. é uma conífera que produz madeira de elevada qualidade, com potencial aplicação na indústria. No entanto, a espécie exibe baixas taxas germinação. Este estudo foi dedicado à otimizar um protocolo para multiplicação brotos S. sempervirens, através da micropropagação. Dois genótipos, adaptados ao Sul do Brasil, foram fonte explantes o in vitro. Utilizou-se meio cultura MS (Murashige Skoog) (50% sua concentração original) complementado reguladores crescimento...
The objective of this search was to quantify the genetic variability in progenies from grápia mother trees natural populations, for initial growth characters seedlings. Seeds were collected 13 trees, four origins, located municipalities Pareci Novo, São José do Sul and Aratiba RS, Seara SC, as well data plants place origin. Biometrics performed on 100 seeds lot each tree, an experiment installed evaluate a completely randomized design. It evaluated seedling emergence speed percentage, stem...
Background: Vegetative propagation from superior individuals allows multiple copies of plants that are genetically identical to the parent plant be obtained. However, vegetative success varies among individual genotypes, with some clones having more difficulty forming roots than others. The aim this study was evaluate genetic gain in Sequoia sempervirens (D.Don) Endl. using parameters describing and initial growth field. Methods: quantified for 16 a completely randomised design consisting 10...
