Análise de imagens na avaliação de danos mecânicos em sementes de soja

Abstract: INTRODUÇÃONo processo de produção de sementes, estas são submetidas a uma série de etapas, para a obtenção de lotes de alta qualidade. Dentre estas, a colheita, o transporte, a movimentação e o beneficiamento sujeitam as sementes a impactos potencialmente causadores de injúrias mecânicas. Assim, os impactos e os danos ocasionados em sementes são praticamente inevitáveis, dentro deste processo, pois podem ocorrer em várias etapas mecanizadas e ser agravados a cada dia, haja vista a demanda crescente por mecaniz… Show more

“…Even so, the seeds of all classes were submitted to the germination test, for the validation of the classes of seeds used. The use of the X-ray image analysis technique is promising in that it may assist with the selection of high quality seeds and the seedling formation process (Lima et al, 2013;Pinto et al, 2012).…”

“…This fact may be attributed to the low moisture content of the grains and to the reduced distance between the collection point and the reservoir of the mechanical sampler (1.92 and 4.0 m) at the storage units of Portelândia and Morrinhos, respectively ( Figure 3D) Carvalho & Novembre (2012) report that the adequate moisture content for mechanical harvest of soybean seeds is 12 to 15.9 % (w.b.) and, according to Pinto et al (2012), the moisture content required to ensure less mechanical damage is between 13 and 15% (w.b.). Smaniotto et al (2014) recommend moisture content of 12% (w.b.)…”

“…Krzyzanowski (1999) state that mainly mechanical damages can occur during processing, which influences the physical and physiological quality of the seeds, since the falls, transport, mats, elevators and other equipment can cause damage to the seeds. Pinto, Mondo, Gomes-Júnior, and Cicero (2012) and Neve et al (2016) argue that mechanical damage is caused by collisions between seeds or on hard surfaces and that such conditions reduce germination and vigour, which may result in a reduction in their sanitary quality. The results of this study converge to suggest that the cracks arising in the seeds come from the transport of seed mass during the drying and later processing, independent of the physical conditions of the air used in the drying process.…”
