Digital images were obtained with the faxitron x-ray equipment in seed of: Pinus douglasiana, Pinus devoniana, Caesalpinia platyloba, Lisyloma divaricatum and Swetenia humilis. The correlation between morphological patterns of structures and the physiological development measured by EP germination analysis (ISTA), determination of pH of the exudate and electrical conductivity was established. The X-ray test turned out to be appropriate to analyze the development of embryos, internal physical damage, integuments damage, embryonic cavity filling, embryo alterations and insect attack. Pinus douglasiana showed correlation (-.88 *) between rudimentary embryos (ER) and normal seedlings (PN) and (.94 *) between embryo severe damage and abnormal seedlings; in Pinus devoniana, (-.75 *) for ER and PN; Caesalpinia platyloba and Lisyloma divaricatum They presented higher percentage of internal fissures and correlation (.89 **) of embryo with severe damage and dead seeds. Swetenia humilis in percentage of rudimentary embryos with dead seeds (.87 *). Regarding the external tonality, the electrical conductivity of the species P. devoniana, P. douglasiana S. humilis and C. platyloba, was higher on average in their seeds of dark testa than those of light tone suggesting a greater degree of deterioration.
