Composição florística e síndromes de polinização e de dispersão da praça Padre Pedro Tenório Raposo, Maceió - AL

Abstract

ABSTRACT

The afforestation of city streets, squares and parks is a necessity for the daily life of the people who live there. Whether in relation to the ecological aspects of the squares, which are mainly related to microclimatic ecosystem services, it is essential to know the existing vegetation in this urban space. This work aimed to conduct a floristic evaluation and pollination and dispersal syndromes of the woody community of the Padre Pedro Tenorio Raposo square, located in Jardim Saúde complex in the municipality of Maceió, AL. The study was conducted through 5 visits to the Padre Pedro Tenorio Raposo square for species identification, organized in a table recording the floristic composition, distributed in families, species, dispersal and pollination syndromes and their origin (exotic or native), during the month of October 2022. A total of 10 families, 50 individuals and 14 species were found. The families with the highest tree species richness were Fabaceae (4), Anacardiaceae (2) and combretaceae (2). The most prominent dispersal syndrome was anemocoria representing 58.33% of the total species, followed by anemocoria (33.33%) and autochoric (8.33%). The fleshy fruits showed a lower percentage, representing 29.31% of total species recorded, the dried fruits represented 70.69% of species, in relation to fruit size, predominated medium size fruits with the percentage of 48.27% of total species, large fruits were 34.48% and small fruits 17.24%. As for the predominant seeds have small size representing 48.27% of species, 27.58% represent large seeds, 24.13% were classified as medium size, in relation to the seeds per diaspore, what predominated were fruits with many seeds per diaspore, representing 65.51% of the total species sampled, the fruits with few seeds represent 39.05% of the total species, and in relation to pollination syndromes represented Meliophilia 66%, chiropterophilia 24%, Entomophilia 8% and Psychophilia 2%. It is concluded that the square did not present a considerable diversity of species, and that the majority are exotic, demonstrating that floristic knowledge of tree species in urbanized areas are essential conditions for the conservation of native species and that obtaining and standardizing the attributes are basic activities for conservation and preservation.
