| Detrimental effects of glyphosate on plant mineral nutrition have been reported in the literature, particularly on Mn uptake and redistribution. However, in most of the experiments conducted so far glyphosate-susceptible plants were used. Effects of glyphosate on Mn absorption kinetics, accumulation, and distribution within the plant, as well as soybean response to Mn as affected by glyphosate were studied in three experiments. In the first experiment, in nutrient solution, the effect of glyphosate on soybean Mn uptake kinetic parameters (Imax, Km and Cmin) was determined. In a second experiment, also in nutrient solution, differential Mn accumulation and distribution were studied for a conventional soybean cultivar and its near-isogenic... |

| Estudou-se o efeito do alumínio sobre a cinetica da absorcao e translocacao de fosforo e sobre a composicao mineral de duas cultivares de trigo, uma sensivel (Anahuac) e outra tolerante (BH-1146) ao aluminio em solucao nutritiva (pH 4,5). Foram utilizados os niveis de zero e 0,5mg.l -1 de aluminio. O aluminio foi aplicado durante o periodo de crescimento das plantas, sendo retirado apenas durante os ensaios de cinetica de absorcao e de translocacao de fosforo. O aluminio reduziu a Vmax das duas cultivares, sendo esta reducao maior para BH-1146 que para a Anahuac. Tambem reduziu ligeiramente o Km da BH-1146, embora tenha aumentado o da Anahuac. A translocacao de fosforo nas cultivares foi influenciada diferencialmente pelo aluminio, havendo reducao na... |

| The effect of particle size (PS), cultivars (C), and their interactions (PS × C) on the hydration of whole wheat flour (WWF) intended for cookie production was evaluated by different approaches. Three Brazilian wheat cultivars and three particle sizes were evaluated. Total arabinoxylans content was affected by PS, increasing up to 6.18 times with the reduction in particle size. Water-soluble arabinoxylans were more influenced by the cultivar. The water absorption capacity by farinograph indicated that the PS had a greater influence, with high absorption in fine particle size flour. Water absorption based on swelling capacity and absorption kinetics by Enslin-Neff device evidenced high water absorption for coarse particle size flour, regardless the... |
