O capim-buffel é uma gramínea que apresenta uma ótima adaptação às condições edafoclimáticas por possuir grande resistência aos períodos de seca. O objetivo deste trabalho foi avaliar a maturação fisiológica e superação de dormência em sementes de C. ciliaris. Utilizou-se delineamento experimental inteiramente casualizado (DIC) tanto para as sementes armazenadas como para as sementes recém-colhidas, com esquema arranjos fatoriais 14 x 2 (quatorze genótipos e duas soluções de embebição, água / nitrato de potássio) e 6 x 2 (seis lotes de duas cultivares e duas soluções de embebição, água / nitrato de potássio), respectivamente. Foram avaliadas sementes de 14 genótipos colhidas em 2006 e armazenados durante 13 anos em câmara fria (10-12°), pertencentes ao Banco de Cenchrus da Embrapa Semiárido. As sementes oriundas de diferentes épocas de colheita foram coletadas ano de 2019 e mantidas em câmara fria e avaliadas de acordo com o período de colheita. Os dados foram analisados inicialmente para a verificação dos pressupostos da análise de variância. Foi aplicado o procedimento do ajuste com emprego dos Modelos Lineares Generalizados (MLG). Após a análise MLG foram analisadas as diferenças significativas dentro de cada Acesso, Tratamento e variáveis estudadas, por meio de comparações de pares de médias pelo teste post-hoc tukey a 5% de significância pelo programa estatístico R. A análise dos dados das sementes armazenadas revelou efeito significativo (p < 0,05) para todas as características avaliadas, exceto germinação e germinação relativa. Para as sementes recém-colhidas, de acordo com a análise de variância, houve diferença significativa (p < 0,05) entre os tratamentos utilizados para superação da dormência das sementes de capim-buffel, em relação a germinação das sementes. Observou-se que os acessos ARIDUS colhidos em diferentes épocas do ano foram os que proporcionaram maior porcentagem de germinação quando tratadas com água destilada. Conclui-se que o tempo de armazenamento pode ter influenciado na qualidade fisiológica das sementes, superando a dormência das sementes armazenadas, mas diminuindo a qualidade fisiológica das mesmas. A utilização do KNO3 não mostrou eficácia para a superação da dormência das sementes recém-colhidas.Submitted by Renata Aline Souza Silva (rassilva@uefs.br) on 2023-04-04T18:37:18Z No. of bitstreams: 1 Dissertacao_Jamille Cardeal da Silva.pdf: 2032491 bytes, checksum: fae5553b3d7b6d7f609e234f4eb7ace4 (MD5)Made available in DSpace on 2023-04-04T18:37:18Z (GMT).
