| The aim of this study was to evaluate the effects of silver nitrate in the in vitro development and conservation of passion fruit plants. Experiments were carried out at the Laboratory of Culture and Tissues, in the National Cassava and Fruits Research Center (EMBRAPA), using microcuttings of Passiflora gibertii N. E. Br., previously cultivated in vitro. The microcuttings were placed in MS media supplemented with silver nitrate at concentrations of 0, 1, 2, 4 and 8 mg·L-1, and, during 30, 60 and 90 days, the following variables were identified: Shooting length (cm), number of roots, number and coloration of leaves. A completely randomized design with 30 replications in a split-plot scheme was employed. Polynomial regression equations were adjusted in... |

| Abstract: Although it has already started in some states, charging for the use of water resources is not yet widespread in Brazil. The aim of this research was to know the perceptions and willingness of farmers in relation to payment for the use of water resources, to make it feasible to collect this fee, introduced by Law No. 9,433, of 1997?Brazilian National Policy of Water Resources (PNRH). In this context, we sought to obtain this knowledge through qualitative research and a semi-structured survey applied to 37 farmers from five hydrographic basins in the Brazilian Federal District. The results, using Iramuteq software, showed the lack of motivation to pay for use of water resources, but also made it clear that the negative situational motivation can... |
