Resumo: | The evaluation of the vigor is of fundamental importance in control programs of seed quality, and accelerated aging test can be used for this purpose. In this sense, the objective of this paper was to study the methodology of the accelerated aging test, seeking to verify their efficiency to identify differences between levels of seed lots vigor of coriander (Coriandrum sativum L.). During the experimental period, the seeds were packed in plastic bags and kept in a controlled environment (16 ° C and 50% RH). For this, the following cultivars Verdão, Super-verdão, Tabocas and Portugues were used, each one represented by three lots. The seeds were tested for germination, first count germination, seedling emergence, speed of emergence, shoot length, dry mass of shoots and accelerated aging (38 and 41 ° C for 48, 72 and 96 hours; method traditional and with use of saline solution), besides the determination of moisture content of seeds. The work was performed at the Laboratory of Seed Analysis and in the greenhouse of the Universidade Federal Rural do Semi-Arido Mossoró-RN. A completely randomized design with four replications of 50 seeds was used. The test results were evaluated individually. The analysis of variance was performed by F test and the means compared by Tukey test (P ≤ 0.05). It was concluded that the accelerated aging test was efficient to evaluate the physiological potential of coriander seeds, and that combinations 41°C/48h (traditional method) and 41°C/72h (with saline solution) constituted in an efficient procedure to detect differences of vigor among seed lots of coriander |

Nesse sentido, o objetivo deste trabalho foi estudar a metodologia do teste de envelhecimento acelerado, procurando-se verificar sua eficiência para identificar diferenças entre níveis de vigor de lotes de sementes de coentro (Coriandrum sativum L.). Durante o período experimental, as sementes foram acondicionadas em sacos plásticos e mantidas em ambiente controlado (16ºC e 50% UR). Para isso, utilizou-se as cultivares Verdão, Super-verdão, Tabocas e Português, cada uma representada por três lotes. As sementes foram submetidas aos testes de germinação, primeira contagem de germinação, emergência de plântulas, índice de velocidade de emergência, comprimento de parte aérea, massa seca de parte aérea e envelhecimento acelerado (38 e 41ºC; 48, 72 e 96 horas; método tradicional e com uso de solução salina), além da determinação do grau de umidade das sementes. Os trabalhos foram realizados no Laboratório de Análises de Sementes e em casa de vegetação, da Universidade Federal Rural do Semi-Árido, Mossoró-RN. Utilizou-se o delineamento inteiramente casualizado, com quatro repetições de 50 sementes. Os resultados dos testes foram avaliados individualmente, quanto à análise de variância pelo teste F e as médias comparadas pelo teste de Tukey (P ≤ 0,05). Diante dos resultados, conclui-se que o teste de envelhecimento acelerado mostrou-se eficiente para avaliar o potencial fisiológico das sementes de coentro; e que as combinações 41°C/48h (tradicional) e 41°C/72h (com solução salina) constituiu-se em procedimento eficiente para detectar diferenças de vigor entre lotes de sementes de coentroCoordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfhttp://repositorio.ufersa.edu.br/retrieve/383/MariaFSP_DISSERT.pdf.jpgporUniversidade Federal Rural do Semi-ÁridoPrograma de Pós-Graduação em FitotecniaUFERSABRCentro de Ciências Agrárias - CCACC-BY-SAinfo:eu-repo/semantics/openAccessCoriandrum sativum L.Vigor testLeafy vegetablesHeat stressCoriandrum sativum L.Teste de vigorHortaliça folhosaEstresse térmicoCNPQ::CIENCIAS AGRARIAS::AGRONOMIAAvaliação do potencial fisiológico de sementes de coentro pelo teste de envelhecimento aceleradoAssessing of the physiological potential of coriander seeds by the accelerated aging testinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisreponame:Biblioteca Digital de Teses e Dissertações da UFERSAinstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSATEXTMariaFSP_DISSERT.pdf.txtMariaFSP_DISSERT.pdf.txtExtracted texttext/plain128299https://repositorio.ufersa.edu.br//bitstream/tede/64/3/MariaFSP_DISSERT.pdf.txtb332281002853cc539da1ebcbc58335bMD53ORIGINALMariaFSP_DISSERT.pdfapplication/pdf658275https://repositorio.ufersa.edu.br//bitstream/tede/64/1/MariaFSP_DISSERT.pdf251a44b08b0ba371e0d3c72f2bdc71f0MD51THUMBNAILMariaFSP_DISSERT.pdf.jpgMariaFSP_DISSERT.pdf.jpgGenerated Thumbnailimage/jpeg2910https://repositorio.ufersa.edu.br//bitstream/tede/64/2/MariaFSP_DISSERT.pdf.jpg8e767af1df0ca39cc4bbb148c722eae1MD52tede/642022-07-05 17:15:54.663oai:repositorio.ufersa.edu.br:tede/64Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufersa.edu.br/PUBhttp://bdtd.ufersa.edu.br/oai/requestdirecaosisbi@ufersa.edu.br|| direcaosisbi@ufersa.edu.bropendoar:2022-07-05T20:15:54Biblioteca Digital de Teses e Dissertações da UFERSA - Universidade Federal Rural do Semi-Árido (UFERSA)false |
