Biometria de frutos e germinação de sementes de Couratari stellata A. C. Smith (Lecythidaceae)

Abstract: RESUMO -Estudou-se as características biométricas de frutos e quantificou-se a germinação em Couratari stellata, espécie cuja altura varia de 30 a 40 m e ocorre em solos de terra firme das Guianas até a região central e oeste da Amazônia. Determinou-se o comprimento e o número de sementes por fruto; número de sementes completamente formadas e de sementes vazias; o grau de umidade; a massa de 100 sementes; a percentagem de germinação, de plântulas anormais e de sementes mortas; e o tempo médio de germinação.
