The predominant phenological patterns for the Caatinga are marked by the rapid replacement of the crowns during the beginning of the rainy season and by the deciduous habit at the beginning of the dry period. The flowering and fruiting process is directly related to the rainy season and mainly in an environment with many variations such as the Caatinga. The present work aimed to characterize the flora of the area where the apiary / school is located, as well as the phenology of ten species representative of the arboreal extract occurring in the Caatinga area in the semi-arid region of Alagoas. The study was conducted at the experimental station Curral do Meio (Sementeira), located in the municipality of Santana do Ipanema, mesoregion of the Sertão region of Alagoas. The observations were made monthly from April 2019 to January 2020, where flowering data (flower buds and anthesis flowers), fruiting (developing fruits and ripe fruits ready for dispersion), sprouting (emergence of new leaves) and leaf fall. In the 50 plots sampled in the experimental area, 1,626 individuals were found, which are distributed in 18 families, 36 genera, 40 species and two indeterminate individuals. During the present study and according to thedata obtained, it can be seen that, for the ten species, the production of new leaves occurred during the rainy season and the beginning of the dry season, which indicates that the sprouting phase is directly related with precipitation. However, when foliar senescence is observed, it can be analyzed that some species concentrated the fall of the leaves in the dry period and the beginning of the rainy season, such as Catingueira, Baraúna and Umburana de Cheiro, while in Pereiro this phenophases were practically registered over almost the entire period, which indicates that the species is gradually replacing the leaves. |
