Previous issue date: 2016 / Funda??o de Amparo ? Pesquisa do Estado de Minas Gerais (FAPEMIG) / Objetivou-se com este trabalho realizar o estudo anat?mico e determinar a composi??o centesimal das sementes de gergelim e c?rtamo, visando identificar as estruturas e constituintes presentes. Os trabalhos foram realizados no Laborat?rio de Sementes do Departamento de Agronomia, no Laborat?rio de Biomassas do Cerrado do Departamento de Nutri??o e no Laborat?rio de Anatomia Vegetal do Departamento de Ci?ncias Biol?gicas da Universidade Federal dos Vales do Jequitinhonha e Mucuri ? UFVJM, Diamantina, MG. Foram utilizadas sementes de gergelim das cultivares CNPA G2 (lote 1) da safra 2010, CNPA G3 (lote 2) da safra 2010, CNPA G4 (lote 3) da safra 2014 e BRS Seda (lote 4) da safra 2015, fornecidas pela Embrapa Algod?o ? Para?ba e gr?os de c?rtamo adquiridos da empresa Terra dos P?ssaros, safra 2015. Para a caracteriza??o dos perfis de lotes de gergelim e c?rtamo, foram analisadas as vari?veis grau de umidade, germina??o, primeira contagem da germina??o, ?ndice de velocidade, emerg?ncia, estande inicial, ?ndice de velocidade de emerg?ncia. Para averiguar a qualidade sanit?ria dos lotes, realizou-se o teste de sanidade. Realizou-se tamb?m a determina??o da composi??o centesimal das sementes de gergelim e c?rtamo. Para a caracteriza??o morfol?gica de semente e pl?ntulas foram avaliados os aspectos biom?tricos e analisadas as caracter?sticas de suas estruturas. Al?m disso, realizaram-se os estudos de an?lise de imagem de sementes, a caracteriza??o anat?mica. Al?m disso, realizaram-se os estudos de an?lise de imagem com aux?lio do sistema SAS e a caracteriza??o anat?mica. Conclui-se que os lotes de sementes de gergelim apresentaram qualidade fisiol?gica semelhante e que parte da qualidade fisiol?gica pode ter sido afetada pela presen?a de pat?genos nos lotes. A composi??o centesimal permitiu confirmar a esp?cie como oleaginosa. A an?lise de imagem permitiu verificar caracter?sticas para a distin??o entre os lotes de sementes de gergelim. As an?lises anat?micas entre os lotes foram semelhantes. Verificou-se que a baixa taxa de germina??o de gr?os de c?rtamo deve-se ? qualidade sanit?ria. Verificou-se que os gr?os de c?rtamo s?o ricos em fibras. / Disserta??o (Mestrado) ? Programa de P?s-Gradua??o em Produ??o Vegetal, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2016. / The objective of this work was to perform an anatomical study and to determine the centesimal composition of sesame and safflower seeds, aiming to identify the structures and constituents present. The work was carried out in the Seed Laboratory of the Agronomy Department, in the Cerrado Biomass Laboratory of the Department of Nutrition and in the Laboratory of Plant Anatomy of the Department of Biological Sciences of the Federal University of the Jequitinhonha and Mucuri Valleys - UFVJM, Diamantina, MG. Seeds of CNPA G2 (lot 1) from the 2010 crop, CNPA G3 (lot 2) from the 2010 crop, CNPA G4 (lot 3) from the 2014 crop and BRS Silk (lot 4) from the 2015 harvest were used, provided by Embrapa Algod?o ? Para?ba and safflower grains purchased from the company Terra dos P?ssaros, harvest 2015. To characterize sesame and safflower seedlings, analysis was conducted for the variables moisture level, germination, first germination count, speed index, emergence, initial booth, emergence speed index. In order to ascertain the sanitary quality of the lots, a sanitary test was performed. The determination of the centesimal composition of the sesame and safflower seeds was also carried out. For the morphological characterization of seed and seedlings the biometric aspects were evaluated and the characteristics of their structures were analyzed. In addition, the studies of seed image analysis, the anatomical characterization, were carried out. In addition, the studies of image analysis were carried out with the help of the SAS System and the anatomical characterization. It was concluded that the sesame seed lots presented similar physiological quality and that part of the physiological quality may have been affected by the presence of pathogens in the lots. The centesimal composition confirmed the species as oleaginous. The image analysis allowed to verify characteristics for the distinction between the lots of sesame seeds. Anatomical analyzes between batches were similar. It was verified that the low rate of germination of safflower grains is due to sanitary quality. It has been found that safflower grains are high in fiber.
