Cerrado; Degradação do habitat, Produção de Frutos, Caryocar brasilienseResumo
Objetivo: Verificar se os efeitos da transformação do Cerrado preservado em ambiente
degradado, afetam a produção e qualidade dos frutos de C. brasiliense no norte de Minas Gerais.
Método: O estudo foi conduzido nesses dois ambientes do Cerrado e em cada área, mediu-se
diâmetro altura do peito e altura dessa espécie. Os frutos foram coletados, pesados e abertos
para a contagem de sementes viáveis e abortadas. Todas as sementes foram pesadas e a
porcentagem de sementes abortadas e frutos predados foi calculada. Resultados: Foram abertos
1.723 frutos e 5.025 sementes foram avaliadas. O peso dos frutos, das sementes e a sua
quantidade foi maior em ambientes degradados. A proporção de sementes abortadas e frutos
predados não diferiram entre os ambientes. Por fim, a altura e a área basal também foram
maiores em ambientes degradados. Conclusão: Antropização de áreas do Cerrado pode
modificar a qualidade dos frutos do pequizeiro, sendo frutos mais pesados em áreas degradadas.
Entretanto, estudos futuros devem avaliar o potencial de germinação dessa espécie.
