Substratos utilizados na produção de mudas de espécies florestais da Amazônia

Abstract

Global demand for wood products is increasing year by year. Reforestation is an effective way to reduce the impacts of forest devastation and generation of scientific information on species. For the production of seedlings of tree species, using the substrate it is one of the variants which can define the quality of the changes produced. Thus, this review paper aims to provide results of previous studies with some native species of the Brazilian Amazon as the substrates that are used and make allowances for future research that may assist in identifying the most suitable substrates for the production of seedlings better quality. The Cupiúba, Angelim Pedra, Para-pará and Marupá showed only a substrate as an efficient way of producing seedlings. The species that presented over a substrate used in d seedling production process were: Itaúba, Cumaru and Paricá. In an overview of the substrates used in the production of seedlings, it was observed that the most common are the manure and sand, appearing as seedling production means for all species except the Angelim Pedra. Currently, studies on this subject are inadequate, substrates generally used in the production of seedlings of native species use based on the mixture of manure and sand to its final composition.
