Efeito do tratamento químico na sanidade de sementes de espécies florestais

This study evaluated the effect of different fungicide and sodium hypochlorite treatments in reducing the incidence of fungi on seeds of native species of the Atlantic rainforest. The experiment was done using the completely randomized design in a 5×5 factorial with five levels of factor A (forest species) and five levels of factor B (chemical treatment and surface disinfection with sodium hypochlorite) with four replications. The fungal genera Fusarium, Alternaria, Aspergillus and Penicillium were identified. The species 'Jacarandáda- Bahia' and 'Ipê-roxo' had lower fungal incidence, 1.0% and 1.3%, respectively. Except for 'Angico Vermelho', the fungicide pencycurom and sodium hypochlorite were not significantly different from the control in the species evaluated. Seed treatment with fungicides 'Captan' and 'Tiram' yielded satisfactory results in reducing the incidence of fungal contamination in forest species seeds.

Restauração florestal visando à conservação de recursos hídricos por meio da combinação linear ponderada

This study evaluated using of Multicriteria Evaluation in a GIS, specifically by Weighted Linear Combination Method for generation of map of priority areas for forest restoration in the initial part of River Pardo Basin, SP, in order to water resources conservation. Aiming to define criteria and restrictions it was used Participatory Techniques, and the following factors had been selected: proximity of the hydrographic network, proximity of forest cover, slope and erodibility of soil. To calculate the weight to each factor it was used the decision-making process, known as Analytic Hierarchy Analysis, this method consists of a paired comparison of factors to determine the relative importance of each. According to Weighted Linear Combination, the very high priority areas have a more limited spatial distribution, with an apparent concentration around the water bodies, outlining a buffer to the river system. The proximity factor of the hydrographic network, and enables the connection forestry, contributed, along with the factor of proximity to forest cover, so there would be the definition of most of the areas with the highest priority in the basin, which concentrate the largest areas of forest and native riparian areas along the hydrographic.
