Visando avaliar os efeitos do fluoreto sobre capim-braquiária, plantas de Brachiaria brizantha e B. decumbens foram submetidas a nevoeiros simulados com fluoreto (10 µg ml-1). Amostras foliares de porções aparentemente sadias foram coletadas 24 horas após a última exposição para análises microscópicas. Folhas, raízes e rizomas foram submetidos à quantificação do teor de fluoreto. As folhas apresentaram necroses...
