Abstract: RESUMO -Pesquisas tem sido conduzidas visando determinar métodos de detecção de organismos geneticamente modificados (OGM), devido, principalmente, à importância sobre a atividade comercial. Atualmente, são utilizados bioensaios, que avaliam características fenotípicas das plântulas, testes de ELISA e Kits, que possibilitam identificar proteínas transgênicas específicas de DNA. O objetivo deste trabalho foi comparar a eficiência dos métodos para detectar sementes de soja Roundup Ready (RR). Amostras de semente… Show more

“…BRSMG 810C, found in the germination test performed with pre-imbibition of seeds in paper towels moistened with the herbicide, was totally inhibited (Table 3); corroborating results obtained by (Tillmann and West, 2004;Cunha et al, 2005;Miranda et al, 2005;and Pereira et al, 2009). As higher the percentage of GM seeds was added in seed samples of non-GM soybean, reductions of normal seedling were detected; indicating the existence of seed mixtures and the feasibility of their detection by the seed analyst.…”

“…In the literature are also found results on: reduction on length of primary root and its thickening (Funguetto et al, 2004;Pereira et al, 2009); paralyzation of development (Pereira et al, 2009); and lack of secondary roots (Funguetto et al, 2004;Cunha et al, 2005;Pereira et al, 2009). By the analysis of Spearman's correlation, it was observed that there was high and statistically signifi cant correlation between the two methods of detections used (r = 0.82; p ≤ 0.0001).…”

“…inibiu o desenvolvimento de plântulas da cultivar convencional, mas essas plântulas chegaram a emitir os primeiros sinais de raízes secundárias, podendo levar a equívocos na interpretação. Por outro lado, como também relatado por Cunha et al (2005), concentrações mais altas do herbicida, como 0,06 e 0,12 % do e.a. causam prejuízos também ao desenvolvimento das plântulas da cultivar GM, como, aumento na taxa de plântulas anormais, redução na emissão de raízes secundárias e no comprimento médio de plântula (Tabelas 3 e 5).…”

“…Anormalidades causadas pelo herbicida são particulares: ausência de raízes secundárias (Goggi and Stahr, 1997;Funguetto et al, 2004;Cunha et al, 2005), redução no comprimento de raiz primária e seu engrossamento (Funguetto et al, 2004) …”
