Desenvolvimento de um modelo para o biospeckle na análise de sementes de feijão (Phaseolus vulgaris L.)

Abstract: RESUMOO biospeckle é uma figura de interferência formada pela reflexão difusa da luz coerente espalhada ao interagir com um objeto que apresenta algum tipo de atividade, biológica ou não. O padrão de interferência se modifica ao longo do tempo devido às estruturas responsáveis pelo espalhamento estarem em atividade. Esse fenômeno tem sido estudado com o intuito de se desenvolver um método rápido e não destrutivo para avaliação de materiais biológicos. A obtenção de um modelo simples que descreva os aspectos es… Show more

“…From its discovery, efforts have been determined in the exploration of the biospeckle as tool no destructive to evaluate the biological activity 23,34,35 . For being no destructive, it allows other studies to be made, concomitant in the same animal, which, of the experimental point of view, it is of great interest 33 .…”

“…The interference pattern modifies along the time due to the responsible structures for the dispersal be in activity. That phenomenon has been studied with the intention of developing a fast method and no destructive for evaluation of biological materials 23,24 . It can be evaluated, besides, viability of seeds with the dynamic biospeckle 25 .…”

“…Specifically for seed analysis, several studies have related the activity presented by the Biospeckle Laser with the quality, viability, deterioration, and germinative potential of commercial seeds, such as beans (Braga et al, 2001;Moreira et al, 2002;Braga et al, 2003;Braga Junior et al, 2005;Rodrigues et al, 2005;Nascimento et al, 2007;Rodrigues et al, 2007), corn (Braga et al, 2001;Peixoto et al, 2018), and coffee (Vivas, 2016). In the works with coffee seed germination, the authors observed that the results obtained by the Biospeckle laser were as efficient as the results of the tetrazolium, with the advantage of not being destructive and expressing the results in near real-time (Vivas, 2016).…”
