Germinação de sementes de três espécies de Fabaceae típicas de floresta estacio...

O presente estudo avalia a germinação de sementes de Anadenanthera colubrina, Acacia polyphylla e Bauhinia cheilantha, espécies típicas de florestas decíduas, submetidas a tratamentos pré-germinativos e ataque de insetos nativos. As sementes de cada espécie foram agrupadas em: sementes escarificadas com lixa, sementes imergidas em água aquecida a 70 °C, sementes com sinais de ataque por insetos e o grupo contro...

Seed germination of three species of Fabaceae typical of seasonally dry forest

This study evaluates seeds germination of Anadenanthera colubrina, Acacia polyphylla and Bauhinia cheilantha, typical species of deciduous forests. Seeds were submitted to pre-germination treatments and attack of native insects. The seeds of each species were grouped in: seeds scarified with sandpaper; seeds immersed in water heated to 70 °C, seeds with signs of attack by herbivore insects and the control group...
