ABSTRACT: In this study, the aim was to determine the influence of potassium nitrate, using different concentrations and immersion times on the dormancy of the seeds of Brachiaria humidicola cv. ?BRS Tupi?. Four experiments were performed adopting a factorial scheme (5x3+1) in different seed lots, for different post-harvest storage durations, during which the seeds were immersed in potassium nitrate solutions of different specific concentrations (0, 0.1, 0.3, 0.5 and 1% KNO3), for three exposure periods (12, 24 and 48h), plus one control (untreated), in a completely randomized design. The characteristics assessed included the imbibition curve, germination, first count and germination rate, as well as viability confirmed by using tetrazolium test. From the findings it was evident that treatments involving 0.1; 0.3; 0.5 and 1% KNO3 or pure water, with a 12 hour-soaking period enabled the stored seeds to germinate well for a minimum of eight months post harvest. Root protrusion was observed 24 hours post seed imbibition, whereas for the untreated seeds, satisfactory germination was observed from at least 12 months post harvest and, in most of the lots, between 18 and 24 months. |

Here we propose a simple one-pot solvothermal method to synthesize well-dispersed CuO catalysts over carbon black surface for application in CO2 electrolysis. Although simple, the route produced catalysts with good performance even in lower CuO contents, increasing the efficiency of the catalytic layer. Films prepared by straightforward dropping on fluorine tin oxide (FTO) substrates were stable (up to 30 hours), showing good activity for CO2 reduction reaction (CO2RR) and controlling the competitive H2 evolution to preferentially form CO2 reduction products (CO, formic acid, ethanol, and acetic acid). The results showed values of almost 50% of faradaic efficiency for products of CO2 reduction, comparable with other more elaborated catalysts reported in the literature, even utilizing cheap support, easy synthesis, and lower potentials |
