Avaliação do Banco de Sementes em três fragmentos com diferentes estágios sucessionais de uma floresta estacional semidecidual submontana município de Laguna Carapã, Mato Grosso do Sul

Abstract

This study aimed to evaluate the soil seed bank in three fragments with different successional stages of a semideciduous forest Submontane in the city of Laguna Caarapã - MS. The study was conducted in the cool of Finance Jatoba reserve, located in the city of Laguna Carapa, Mato Grosso do Sul, between the coordinates 22o42'24.56 "S; 52o02'43.75 "W 22o41'37.19 and" S; 55o01'55.40 "W. Samples were collected in the dry season in the rainy season. 20 samples were collected for each area totaling 60 samples. The samples were collected in a quadrant 20 x 20 cm and 5 cm deep without litter. The soil seed bank along the two evaluations carried out during the dry and rainy season had its floristic composition consisting of 1438 trees and shrubs individuals. The sampled individuals were classified into 14 species belonging to 14 genera and 11 families and 1 individual classified as morphospecies. Life forms identified in the soil seed bank were studied herbaceous species with 71.99% of the individuals, tree, with 11.88%, grasses, with 11.04% and lianas with 2.22%. The low diversity of species sampled in this study, it may suggest the occurrence of a transient seed bank given that the results did not reflect the regeneration study in the same area. Therefore, it is recommended to carry out more specific searches throughout the year to understand all its dynamics.
