Morphological study of squash seeds at different stages of maturation through the use of X-ray Rev. Ciênc. Agron.
Silva,Patricia Pereira da; Barros,Antonio Carlos Souza Albuquerque; Marcos Filho,Julio; Gomes Junior,Francisco Guilhien; Nascimento,Warley Marcos.
ABSTRACT Analysis of images has been recently used in order to both assess seed quality and elucidate some aspects of seed physiology, including X-ray tests and other resources. The objective of this study was to examine whether the X-ray may be successfully used to detect physical abnormalities, and relate their occurrence with physiological potential of tetsukabuto type squash seeds. Fruits were harvested at different maturation stages (15, 30, 45, 60 and 75 days after anthesis - DAA) and temporarily or not stored for 20 days. Seeds were radiographed using an intensity of 25 kV for 40 seconds and then germinated under alternating temperatures of 20-30 ºC. After four and eight days, percentages of normal and abnormal seedlings and dead seeds were...

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...
