Resumo: | Soil bioengineering is a discipline of civil engineering that uses live elements as construction materials in order to produce technical effects, without neglecting aesthetic and ecological issues. Plant propagules are one of the most employed vegetative materials in different soil bioengineering schemes. These propagules are used to stabilize soil engineering properties by means of the posterior plant root development. Live material, consisting, in general, of wooden stakes and stem posts, could not be stored indefinitely, having a maximum or an optimal storage period before being implanted as construction material in soil bioengineering interventions. The objective of this work is to evaluate the most appropriate storage to preserve plant propagules (wooden cuttings) viability. Three species had been used for the study: Phyllanthus sellowianus, Salix humboldtiana and Sebastiania schottiana. Propagules of those three species are stored in three different wrap materials: Kraft paper, moist transparent polyethylene and dry transparent polyethylene. Each packed set is then preserved in two different temperature states (room temperature – unrefrigerated – and refrigerated environment at 8°C ± 2ºC). The vegetative viability of the material is verified by means of the success rate (IP) of the implanted sets, evaluated after different storage periods: reference sampling (non-stored), 3, 6, 9, 12, and 15 days. The live cuttings had their IP evaluated after 60 days of planting. The results show that the dry polyethylene storage produced the best preserving effects. Storage in Kraft paper, allowed moisture exchange between plant material and external environment. This fact leads to fast dehydration and death of the plant material. Moist polyethylene packing, meanwhile, creates conditions for the proliferation of fungi and bacteria, also reducing the vitality of the stored material. The results indicate that the storage of the studied species is feasible in dry polyethylene packing for up to 15 days (maximum tested period). The main refrigeration effects are: to decrease fungi and bacteria proliferation and to improve S. humboldtiana viability. S. schottiana success rate is significantly improved when it is stored by at least three days before planting The obtained results are useful as important information for planning and scheduling soil bioengineering works execution. |

Entre outras formas, propágulos vegetativos são utilizados em diferentes arranjos técnicos visando melhorar as propriedades de engenharia dos solos através do desenvolvimento radicular das plantas. Os materiais vivos, sejam estacas lenhosas ou outras partes da planta, possuem um período ideal ou máximo de estocagem antes de sua utilização em obra. O objetivo deste trabalho é avaliar formas de armazenamento que melhor preservem a viabilidade de propágulos vegetativos (estacas lenhosas). Três espécies foram utilizadas para o estudo: Phyllanthus sellowianus, Salix humboldtiana e Sebastiania schottiana. Propágulos vegetativos (estacas lenhosas) dessas espécies foram acondicionados para armazenamento em três diferentes formas: papel Kraft, polietileno transparente úmido e polietileno transparente seco. Esses foram conservados em duas condições de acondicionamento (temperatura ambiente - sem refrigeração - e ambiente refrigerado com temperatura de 8°C ± 2ºC). A viabilidade do material foi verificada através do índice de pega (IP) do material plantado, avaliado após diferentes períodos de armazenamento: testemunha (sem armazenamento), 3, 6, 9, 12, e 15 dias. As estacas tiveram seu IP avaliado após 60 dias do plantio. Os resultados mostram que o armazenamento em embalagens de polipropileno seco produz os melhores efeitos de preservação. O acondicionamento em embalagem de papel Kraft, permite a troca de umidade entre o material vegetal e o ambiente externo, o que leva à rápida desidratação e à morte do material vegetal. Já a embalagem de polietileno úmida cria condições para a proliferação de fungos e bactérias o que, igualmente, reduz a vitalidade do material armazenado. Os resultados obtidos mostram que o armazenamento do material vegetal para as espécies estudadas é viável em embalagem de polietileno seco por até 15 dias (máximo testado). A refrigeração reduz a proliferação de patógenos e aumenta o IP de S. humboldtiana. Já a espécie S. schottiana tem seu IP significativamente melhorado quando armazenada por pelo menos três dias antes do plantio. As informações obtidas são úteis no planejamento do cronograma de execução de obras que utilizem propágulos lenhosos vivos.Universidade Federal de Santa MariaBrasilRecursos Florestais e Engenharia FlorestalUFSMPrograma de Pós-Graduação em Engenharia FlorestalCentro de Ciências RuraisSutili, Fabrício Jaqueshttp://lattes.cnpq.br/5871729986469148Gavassoni Neto, ElvidioMantovani, Nilton CésarCadoná, Suelen Camargo2021-07-08T20:50:14Z2021-07-08T20:50:14Z2014-02-28info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://repositorio.ufsm.br/handle/1/21357porAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSM2022-06-13T17:36:37Zoai:repositorio.ufsm.br:1/21357Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2022-06-13T17:36:37Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false |
