Zusammenfassung:Image analysis through X-ray technique has been receiving great attention due to its importance in identifying internal damage in seeds quickly and accurately, in addition to being a non-destructive method. The aim of this study was to assess the use of X-rays to evaluate the internal morphology of seeds of green manure species. Seeds of Lupinus albus L., Cajanus cajan (L.) Millsp., Canavalia ensiformis (L.) DC. and Stylosanthes spp. were radiographed. Two hundred seeds were studied for each species, and intact seeds, seeds with mechanical damage, damage caused by insects and deteriorated tissues were recorded, considering the severity and location of the damage. The same seeds were subjected to a germination test. It was concluded that image analysis using X-ray technique was effective in detecting internal damage in seeds of some green manure species and it has relationship with negative aspects in germination. RESUMO: A análise de imagens por meio da técnica de raios X vem recebendo grande destaque por ser uma técnica importante para identificação de danos internos em sementes, de forma rápida e precisa, além de ser um método não destrutivo. O objetivo do trabalho foi verificar a utilização de raios x para avaliação da morfologia interna de sementes de espécies de adubos verdes. Sementes de tremoço-branco (Lupinus albus L.), feijão guandu-anão (Cajanus cajan (L.) Millsp.), feijão-de-porco (Canavalia ensiformis (L.) DC.) e estilosantes (Stylosanthes spp.) foram radiografadas, sendo estudadas 200 sementes para cada espécie e contabilizadas as sementes intactas e as com danos mecânicos, danos causados por insetos e tecidos deteriorados, considerando a severidade e localização dos danos. As mesmas sementes foram avaliadas pelo teste de germinação. Concluiu-se que a análise de imagens por meio da técnica de raios X é eficiente na detecção de danos internos em sementes das espécies de adubos verdes estudadas e apresenta relação com os aspectos negativos na germinação.
