Resumo: | Paubrasilia echinata is a perennial species occurring in forests of Atlantic forest and has a dense and resistant wood, threatened with extinction due to its inadequate exploitation. Considering the economic and environmental importance, it is necessary to produce quality seedlings with good parameters, which show a uniform growth and a lower percentage of mortality in the field. Thus, the present work had as objective to perform a morphological analysis for quality of pau-brasil seedlings produced in the nursery of the Federal University of Sergipe, besides the adjustment of equations for estimation of Dickson’s Quality Index (DQI), dry shoot weight (DSW) and dry root weight (DRW) as an alternative to the use of destructive methods for the specie. Three evaluations were carried out biweekly with 50 samples of the 540 sapwood seedlings produced. The variables used were: diameter at neck height (DNH), height (H) and number of leaves (NL), dry and wet weight of 10 seedlings at each evaluation. We also tested 15 equations, aiming to generate the general model for all variables of interest. For the DAC and H, the seedlings obtained values above 5 mm and 20 cm respectively. It was observed that the dry mass weight, in the DSW/DRW ratio, the mean value reached was 3.24 and the DQI was 0.53. The best equations for PMSPA and PMSR, respectively, were at 12 and 15. According to the morphological parameters presented, the pau-brasil seedlings are suitable for planting even though it presents a low DQI. |

Considering the economic and environmental importance, it is necessary to produce quality seedlings with good parameters, which show a uniform growth and a lower percentage of mortality in the field. Thus, the present work had as objective to perform a morphological analysis for quality of pau-brasil seedlings produced in the nursery of the Federal University of Sergipe, besides the adjustment of equations for estimation of Dickson’s Quality Index (DQI), dry shoot weight (DSW) and dry root weight (DRW) as an alternative to the use of destructive methods for the specie.

We also tested 15 equations, aiming to generate the general model for all variables of interest. For the DAC and H, the seedlings obtained values above 5 mm and 20 cm respectively. It was observed that the dry mass weight, in the DSW/DRW ratio, the mean value reached was 3.24 and the DQI was 0.53. The best equations for PMSPA and PMSR, respectively, were at 12 and 15.

Tendo em vista a importância econômica e ambiental, se faz necessário a produção de mudas com parâmetros de qualidade aceitáveis, com crescimento análogo e, consequentemente, menor mortalidade no campo. Assim, o presente trabalho teve como objetivo realizar análise morfológica para qualidade de mudas de pau-brasil, além do ajuste de equações para estimativa do Índice de qualidade de Dickson (IQD), Peso da matéria seca da parte aérea (PMSPA) e Peso da matéria seca da raiz (PMSR) como alternativa ao uso de métodos destrutivos para a espécie. Foram realizadas três avaliações quinzenalmente com 50 amostras das 540 mudas de pau-brasil. As variáveis utilizadas foram: diâmetro a altura do colo (DAC), altura (H) e o número de folhas (NF), peso seco e úmido de 10 mudas em cada avaliação. Foram testadas 15 equações, visando gerar o modelo geral para todas as variáveis de interesse. Para o DAC e H, as mudas obtiveram valores acima de 5 mm e 20 cm, respectivamente. Observou-se que o peso de massa seca, na relação PMSPA/PMSR o valor médio alcançado foi de 3,24 e o IQD de 0,53. As melhores equações com ajustes para IQD foram de 3 a 6. As melhores equações para PMSPA e PMSR, respectivamente, foram a 12 e 15. Conforme os parâmetros morfológicos apresentados, as mudas de pau-brasil estão aptas ao plantio mesmo apresentando baixo IQD.São Cristóvão, SEporAssociação Sergipana de CiênciaScientia PlenaHeliófitasÍndice de Qualidade de DicksonModelos linearesLinear modelsHeliophitesDickson Quality IndexAvaliação dos parâmetros morfológicos da qualidade de mudas de Paubrasilia echinata (pau-brasil) em viveiro florestalEvaluation of morphological parameters for seedling quality of Paubrasilia echinata (pau-brasil) in forest nurseryinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlereponame:Repositório Institucional da UFSinstname:Universidade Federal de Sergipe (UFS)instacron:UFSinfo:eu-repo/semantics/openAccessLICENSElicense.txtlicense.txttext/plain; charset=utf-81475https://ri.ufs.br/jspui/bitstream/riufs/11639/1/license.txt098cbbf65c2c15e1fb2e49c5d306a44cMD51ORIGINALParametrosMorfologicosPaubrasiliaEchinata.pdfParametrosMorfologicosPaubrasiliaEchinata.pdfapplication/pdf851163https://ri.ufs.br/jspui/bitstream/riufs/11639/2/ParametrosMorfologicosPaubrasiliaEchinata.pdf5a00ed6978a299748833f0271732527dMD52TEXTParametrosMorfologicosPaubrasiliaEchinata.pdf.txtParametrosMorfologicosPaubrasiliaEchinata.pdf.txtExtracted texttext/plain36585https://ri.ufs.br/jspui/bitstream/riufs/11639/3/ParametrosMorfologicosPaubrasiliaEchinata.pdf.txt406c8b0fdcf5ad3bfcfb143585c089afMD53THUMBNAILParametrosMorfologicosPaubrasiliaEchinata.pdf.jpgParametrosMorfologicosPaubrasiliaEchinata.pdf.jpgGenerated Thumbnailimage/jpeg1628https://ri.ufs.br/jspui/bitstream/riufs/11639/4/ParametrosMorfologicosPaubrasiliaEchinata.pdf.jpg590fa5480872e18e71f8b20c3c6dacb1MD54riufs/116392019-08-07 17:29:49.272oai:ufs.br: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Repositório InstitucionalPUBhttps://ri.ufs.br/oai/requestrepositorio@academico.ufs.bropendoar:2019-08-07T20:29:49Repositório Institucional da UFS - Universidade Federal de Sergipe (UFS)false |
