![]() The forest species, particularly the ones from Cerrado, are characterized by the high incidence of predation, empty fruit and deficiency in the formation of the embryo. In this sense, the capture and processing of the image which has been x-rayed has allowed the establishment of relations between integrity, morphology and determination of the physiological potential of the seeds (Marcos et al., 2010). The seed analysis through the radiographic images obtained through the x-ray testing is a relatively recent alternative in order to immediately classify the several internal morphological aspects of the seeds (Gomes, 2010). In this context, the use of non-destructive procedures which provide efficiency in the identification of empty, partially full and full seeds, like the x-ray testing may be considered an indicative of physiological quality of the seeds of these forestry species. The environmental compensations, like the compulsory replacement of native forests in rural properties, and the recovery of degraded areas, aiming at facing federal and state laws, prompted an increase in seed demands of native arbor forest species, which constitute basic input in the replacement and conservation programs of the ecosystem. (de Melo et al., 2009 Albuquerque and Guimarães, 2008). The morphophysiological quality evaluation of the seed groups is an essential process, which is of great importance for several phases of the production chain of the sector of seed production, significantly contributing for the maintenance and quality enhancement of this input. It is widely used for commercial and ornamental purposes with its planting being more widely recommended in the agroforestry system in degraded areas recovery programs (Lorenzi, 2008 Pacheco et al., 2007 Lopes et al., 2010). It is a species which naturally occurs in the Cerrado and in the forestcerrado transition zone and is usually found in well-drained soils. popularly known as uruvalheira, jacarandá-docampo, faveiro, belongs to the Fabaceae family. Key words: Cerrado, image analysis, forest management, germination. and can also be used for the analysis of the internal morphology of other forest species. The importance of a methodology of easy implementation, aiming at estimating the germinative power of the groups of seeds, was proved by the x-ray tests in seeds of Platypodium elegans Vog. There is a relationship between the internal morphology of seeds and the results of the germination test. The x-ray test, in 26 kV for 1.2 seconds intensity was efficient in Platypodium elegans Vog. seeds is promising in quality of seed groups detection, assisting in empty and partially full seeds separation, invalidating their immediate use or storage. From the results obtained in this work, the use of x-ray test with Platypodium elegans Vog. Statistical design in factorial 3x3, with three groups and three categories. For each seed category, germination tests were performed. Three categories of seeds were established: full, empty and partially full. Next, the seeds were classified according to their internal morphology as seen in the radiographic images. ![]() 200 radiographic images were taken of each group and the tests were taken with the seeds set at 28.0 cm from the source of x-rays. ![]() seeds through the X-ray tests and to verify their relation with germination. The objective of this work was to evaluate the internal morphology of Platypodium elegans Vog. Brasília DF, Brasil.Ģ Universidade de Brasília.
