“…treated seedlings (1.4 cm/cm) than in bare-root seedlings (0.04 cm/cm). Initial RCD had a large effect due to more carbohydrate reserves in the remaining roots and stem of rootstock seedlings, enabling plants to have a more vigorous and balanced sprouting and leaf formation (LANDHAUSSER et al 2012;ZHU et al 2012). In the bare-root seedlings this effect was smaller because larger seedlings had a larger stem and therefore higher evapotranspiration, eliminating any advantage that larger carbohydrate reserves could have.…”

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.

“…Consequently, it results in a great flow of sap and considerable loss of carbohydrates that serve as the primary energy reserve of trees. Resprouting after severe damage and loss of a majority of aboveground biomass requires resources to support the development of new resprouts (Bond and Midgley 2001;Zhu et al 2012). Severe depletion of carbohydrate reserves can affect the regeneration capacity of the tree after damage (Luostarinen and Kauppi 2005) and can lead to its death.…”

The main aim of this study was to determine the effectiveness of removing invasive downy birch in non-forest peatland applying a single cut. We tested whether the removal of birch was positively related to the height of cutting, season of the year and age of the trees. Our study showed that birch trees cut at the higher tested height exhibited a lower survival rate than those cut below or just above the ground level. Furthermore, the winter cut produced more non-sprouting stumps than those recorded after the cut performed in autumn. In our opinion, winter cutting at breast height is the best management strategy for downy birch control. However, we suppose that the effective elimination of birch by applying a single cut is not possible, and the treatment should be repeated in subsequent years or boosted by additional treatments.

“…The non-structural carbohydrate pool is particularly important for root growth and maintenance in resprouting species. In fact, non-structural carbohydrate pools stored in root systems of resprouters are directly related to resprouting ability and initial growth (Drake et al 2009;Zhu et al 2012) and have been shown to be much larger in resprouters than in nonsprouting species (Bond and Midgley 2001 and references therein). A greater amount of parenchyma and more carbohydrate storage may lead to higher maintenance respiration costs in root systems of vegetatively regenerated trees relative to sexually originated ones.…”
