Soybean seeds may show low germination when evaluated by the paper towel germination test due to high percentages of abnormal seedlings, typical of imbibition damage. This research evaluated the effect of initial seed moisture content (SMC) of different soybean cultivars and production locations on the occurrence of imbibition damage. Treatments consisted of seedlots of four cultivars (Embrapa 48, BRS 184, BRS 232 and BRS 245RR) from 4 Brazilian production locations (Ponta Grossa-PR, Londrina-PR, Mauá da Serra-PR and Orlândia-SP). Seed moisture content was adjusted to 9%, 11%, 13%, 15% and 17% prior to the evaluation of imbibition damage. A completely randomized experimental design was used with four replications. Analysis of variance and mean comparison by the Tukey and the Dunnet tests (P ? 0.05) were applied for statistical analysis. It was concluded that the increase of seed moisture content is affected by cultivar and initial seed quality. Additionally, it was observed that imbibition damage is not detected when initial seed moisture is equal to or higher than 15%. |

The improper disposal of potentially dangerous metal-containing wastes is detrimental to the environment and human health, requiring the development of easy methods for removing these cations, particularly in water bodies. The influence of different surface-charged lamellar materials on the sorption and desorption of Cr6+, Cu2+, and Mn2+ in aqueous solutions was investigated by modifying polyacrylamide/methylcellulose (PAc-MC) hydrogels with bentonite or hydrotalcite. In disk or powder form, the adsorption and desorption capabilities were examined. Regardless of their shape, the bentonite-hydrogel and unmodified hydrogel revealed lower contaminant retention capacities on polymeric structures. In contrast, the hydrotalcite-hydrogel demonstrated a stronger affinity for holding ions in the nanocomposite polymeric structure. The nanocomposite produced by calcining hydrotalcite at 550 ◦C displayed the best retention properties. Shapes of disks or powders did not affect sorption capacity, but disks were considerably more practical for recovering processed materials. These findings contribute to comprehending the retention capacity of modified hydrogels (or modified nanocomposites). |
