“…Based on an analysis of the seeds of the three cultivars and two lines, it was seen that severe damage to the embryonic axis and cotyledons resulted in dead seeds or abnormal seedlings. The same result was also verified in common bean seeds (Forti et al, 2008) and in soybean seeds (Pinto et al, 2009), where stinkbug damage ranked as severe, that is, occurring to the embryonic axis and, or the cotyledons, resulted in abnormal seedlings or dead seeds.…”

In Brazil, the cowpea [Vigna unguiculata (L.) Walp], is important in the Northeast Region, where it is typically grown on family farms. The importance of the damage caused to the seed quality of this species by stored pests has been described in various studies. Using X-ray, it is possible to see the internal seed structures and identify possible changes and damage. The objective of this study was to identify the damage caused by the weevil [Callosobruchus maculatus (Fabr.)] by analyzing X-ray and evaluate its relationship to the physiological quality of the cowpea seed. Three cultivars were used (IPA-206, BRS-Pajeu and BRS-Potengi) and two lines (L 281.005 and L ESP 10). The samples were exposed to X-ray and germination test to determine the cause-effect relationship between weevil damage and seed germination. X-ray images were evaluated to determine damage severity and location in the seed. Seed damage classified as severe, located in the embryonic axis or in the cotyledons, resulted in abnormal seedlings or dead seeds. The X-ray test, therefore, is efficient for evaluating weevil damage in cowpea seeds and the damage caused to be associated with any resulting adverse germination effects.

“…The X-ray test has also been effective in identifying injuries from "moisture" in soybean seeds (Obando-Flor et al, 2004;Forti et al, 2010) and from stink bugs in soybean (Obando-Flor et al, 2004;Pinto et al, 2009b) and in common bean (Forti et al, 2008) seeds, evaluation of fissures in rice seeds (Menezes et al, 2012), and mechanical injuries in maize seeds (Carvalho et al, 1999;Cicero and Banzatto-Junior, 2003;Gomes-Junior and Cicero, 2012).…”

-The X-ray test is a simple, fast, non-destructive, and highly precise test that enables detailed examination of internal seed morphology and identification of seed damage and its location and type. The objective of the present study was to evaluate the efficiency of the X-ray test and the relationship between the structure of Crotalaria juncea seeds and germination. Six lots of Crotalaria juncea seeds of the IAC-KR1 cultivar were subjected to X-ray and germination tests. Normal and abnormal seedlings and dead seeds were photographed and analyzed together with the X-ray images of the seeds. Results showed that analysis of X-ray images is effective in identifying mechanical damage, stink bug damage, and deteriorated tissues in Crotalaria juncea seeds and is able to establish an association between their occurrence and germination.Index terms: image analysis, germination, internal morphology.Análise radiográfica para avaliação da estrutura de sementes de Crotalaria juncea L.RESUMO -O teste de raios X é um teste rápido, simples, não destrutivo e de alta precisão, que possibilita examinar com detalhes, a morfologia interna da semente, identificar áreas danificadas, sua localização e tipos de danos. O objetivo na presente pesquisa foi avaliar a eficiência do teste de raios X e relacionar a estrutura de sementes de Crotalaria juncea com a germinação. Foram utilizados seis lotes de sementes de Crotalaria juncea, cultivar IAC-KR1. As sementes foram submetidas aos testes de raios X e germinação. As plântulas normais, anormais e sementes mortas foram fotografadas e analisadas paralelamente às imagens radiográficas das sementes. Verificou-se que análise de imagens radiográficas possibilita a identificação de danos mecânicos, danos por percevejos e tecidos deteriorados em sementes de Crotalaria juncea, com efeitos negativos à germinação.Termos para indexação: análise de imagens, germinação, morfologia interna.

“…A técnica de raios-X também permitiu relacionar a morfologia de sementes com a germinação ou morfologia das plântulas de diversas espécies agrícolas e florestais (Van der Burg et al, 1994;Battisti et al, 2000;Machado e Cicero, 2003;Oliveira et al, 2003;Mondo e Cícero, 2005;Pupim et al, 2008;Santos et al, 2009;Pinto et al, 2009a;Carvalho et al, 2010;Gagliardi e MarcosFilho, 2011), identificar injúrias por umidade em sementes de soja (Obando Flor et al, 2004;Forti et al, 2010) e por percevejo em sementes de soja (Obando Flor et al, 2004;Pinto et al, 2009b) e de feijão (Forti et al, 2008), além de injúrias mecânicas em sementes de milho (Cícero et al, 1998;Carvalho et al, 1999;Cicero e Banzatto Junior, 2003).…”

RESUMO -O crescente interesse pelo uso de combustíveis renováveis nos últimos anos fez com que culturas oleaginosas, como a mamona, se tornassem importante objeto de estudo. No entanto, para a instalação de campos desta cultura, é imprescindível o uso de sementes de alta qualidade. O objetivo da pesquisa contida neste trabalho foi verificar a eficiência do teste de raios-X na avaliação da qualidade de sementes de mamona após a colheita e armazenamento. Três lotes de sementes da cv. 'IAC-2028' (provenientes, respectivamente, dos racemos primário, secundário e terciário) e dois lotes da cv. 'Guarani' (lotes comerciais com sementes de todos os racemos misturados) foram avaliados de acordo com a morfologia interna pelo teste de raios-X, na intensidade de 20 kV por 60 segundos de exposição. Posteriormente, as sementes radiografadas foram submetidas ao teste de germinação de modo a relacionar a morfologia interna das sementes com as respectivas plântulas normais, anormais ou sementes mortas. Após seis meses de armazenamento acondicionadas em sacos de papel Kraft, em condições não controladas de temperatura e umidade relativa do ar, amostras dessas sementes foram novamente avaliadas pelo teste de raios-X. O teste de raios-X é eficiente para avaliar a morfologia interna das sementes e seus reflexos no potencial fisiológico.Termos para indexação: Ricinus communis L., análise de imagens, germinação.X-Ray test to evaluate castor bean seed quality ABSTRACT -The increasing interest in using biodiesel as an alternative energy source is increasing the importance of some oleaginous crops, such as castor bean, although high quality seeds must be used. The objective of this study was to evaluate the efficiency of the X-Ray test in determining castor bean seed quality after harvesting and storage. The internal seed morphology of three seed lots of the 'IAC 2028' cultivar (from the first, second and third raceme, respectively) and two seed lots of the 'Guarani' cultivar (commercial seed lots with the three racemes mixed) was evaluated with the X-Ray test, at a radiation intensity of 20 kV and an exposure time of 60 seconds. Radiographed seeds were submitted to a germination test to determine any relationship between internal morphology and the quantity of normal and abnormal seedlings, and dead seeds. After six months of storage in paper bags, with no control of temperature or air relative humidity, seed samples were once more evaluated by the X-Ray test. The X-Ray test is effective in evaluating the internal morphology of castor bean seeds and its effects on seed physiological potential.
