Características fisiológicas de biótipos de Conyza bonariensis Resistentes ao glyphosate cultivados sob competição

Abstract: RESUMO -A resistência de plantas daninhas a herbicidas está relacionada a modificações metabólicas, enzimáticas, fisiológicas e/ou anatômicas. Aliado a essas mudanças, a planta pode aumentar ou diminuir as atividades fisiológicas, o que, consequentemente, pode afetar o seu crescimento e desenvolvimento. Assim, biótipos resistentes podem apresentar melhor adaptação ecológica em ambientes de cultivo e tornar-se predominantes devido à eliminação das plantas sensíveis. Em condições de seleção natural, biótipos com… Show more

“…Despite our inferences, herbicide resistance may (GALON et al 2013, TORRES-GARCÍA et al 2015, YANNICCARI et al 2016 or may not (DUFF et al 2009, TRAVLOS & CHACHALIS 2013, VILA-AIUB et al 2014) constitute fitness costs (including seed production and vigor) in the resistant populations. In some cases, by the way, the glyphosate-resistant biotype was more competitive than the glyphosate-susceptible biotype, particularly when grown at high densities and under moisture-deficit stress (SHRESTHA et al 2010).…”

“…Authors had found the resistance to glyphosate providing a penalty for C. bonariensis resistant biotypes regarding on plant growth (MOREIRA et al 2010) and gas exchange (GALON et al 2013). In addition, glyphosate resistance also reduced the seed production of Lolium multiflorum L. (VARGAS et al 2005, FERREIRA et al 2008) and Lolium rigidum Gaud.…”

“…In addition, the prevention or management of herbicideresistant weed populations requires unusual strategies using alternative herbicides, as well as information on species ecology. However, this information is frequently scarce (Moreira et al, 2010a) and is usually limited to the emergence of resistant biotypes (Vargas et al, 2007;Vidal et al, 2007) or to competitive aspects (Shrestha et al, 2010;Galon et al, 2013;Silva et al, 2014b).…”

“…Os processos de transpiração e captura de CO2 só ocorrem quando os estômatos estão abertos, bem como a Gs. (GALON et al, 2010;GALON et al, 2013;MANABE et al, 2014). Com relação à massa da matéria seca total (MST) contatou-se a formação de seis grupos segundo o critério de agrupamento utilizado.…”
