Anatomy and ontogeny of the pericarp of Pterodon emarginatus Vogel (Fabaceae, Faboideae), with emphasis on secretory ducts.
Discrepant and incomplete interpretations of fruits of Pterodon have been published, especially on the structural interpretation of the pericarp portion that remain attached to the seed upon dispersal. The present work clarified these doubts and analyzed ultrastructural aspects of the Pterodon emarginatus diaspores using light and transmission electron microscopes. Cell divisions are prevalent ...
متن کاملAnatomy and ontogeny of Pterodon emarginatus (Fabaceae: Faboideae) seed.

متن کاملDefinição e Avaliação de uma Abordagem para Extração e Catalogação de Conteúdo Obtido da Deep Web
This paper presents an approach for the extraction and labeling of data presented in Deep Web databases. Such a data are extracted from a set of HTML pages generated as the result of a query posed on the hidden database through a Web form. Data labeling (and persistence) aims at providing further structured queries over this hidden content. Preliminary experiments had demonstrated that the prop...
