Última X-ray microtomography in comparison to radiographic analysis of mechanically damaged maize seeds and its effect on seed germination Agronomy Gomes Junior, Francisco Guilhien; Cícero, Silvio Moure; Vaz, Carlos Manoel Pedro; Lasso, Paulo Renato Orlandi. Among the most relevant aspects of seed production, mechanical damage may affect seed germination and reduce health and vigor. This study introduces a noninvasive high-resolution imaging procedure for evaluating the mechanical damage to maize seeds and the effects on seed germination. Seeds with different levels of mechanical damage were evaluated using a benchtop micro-computed tomography system (micro-CT) and digital X-ray equipment. The two-dimensional transaxial, coronal and sagittal micro-CT sections were used to inspect the seed anatomy and the mechanical injuries in the internal seed tissue. Germination tests were performed using paper towel rolls (25°C for 7 days) in which the seedling length was evaluated on a daily basis, and the seedling dry...

Thus, this research adjusted a methodology that aims to relate the internal morphology of broccoli seeds to their physiological potential through radiographic analysis of seeds and computerized images of seedlings. The broccoli cultivars used were Piracicaba Precoce and Ramoso Santana represented by ten lots of each one. The study was conducted using X-ray imaging for seed analysis, in which the area, density and circularity measures were obtained as internal morphology characteristics of seeds. After a germination test, the seedling length was... Tipo: Info:eu-repo/semantics/article Palavras-chave: Tecnologia de Sementes internal morphology; X-ray; Vigor; Seedling length.
