“…In fruits with more than one seed, the fruit is constricted between the seeds, but they are false septa, as observed in different legumes (Barroso et al, 2007;Silva and Môro, 2008). According to Ducke (1925), tento's vegetables have one to three bicolor seeds.…”

“…The characterization of Fabaceae's morphological http://dx.doi.org/10.1590/2317-1545v37n4151436 and anatomical structures of fruits, seeds and seedlings is the goal of several studies aiming to solve taxonomic problems, subsidize species identification, and understand ecological and physiological strategies, among others (Melo-Pinna et al, 1999;Barroso et al, 2007;Silva and Môro, 2008). Seeds internal and external morphology, combined with seedlings observations, allow the identification of structures, offering, in the laboratory, subsidies for the correct interpretation of germination, identification and certification tests of physiological quality.…”

“…Seeds internal and external morphology, combined with seedlings observations, allow the identification of structures, offering, in the laboratory, subsidies for the correct interpretation of germination, identification and certification tests of physiological quality. Therefore, it can assist seed technology studies, and, in the nursery, contribute to the recognition of the species and methods suitability for producing seedlings for various purposes (Andrade et al, 2003;Rego et al, 2007). However, for most Amazonian legume species, basic information about the fruits, seeds and seedlings morphology and anatomy are sparse, and for tento, fruit and seed morphology is partially dealt with by Ducke (1925).…”

-Ormosia paraensis Ducke, known as "tento", has seeds that are used to make handcrafts and wood that is worked on by furniture makers. For forest identification and seeds technology, the information about the morphoanatomy of their fruits, seeds and seedlings is scarce. Therefore, the purpose of this study was to morphoanatomically describe the fruit, seeds and the post-seminal development of "tento". For the morphoanatomical description, the evaluations were examined by optical and electron microscopy scanning. The fruit is a nutant legume, brown to black, dehiscent and with one or two seeds of lateral placentation, being the epicarp slim, the mesocarp woody and the endocarp spongy, measuring about 4.4 cm, 3.9 cm and 2.0 cm in length, width and thickness, respectively. The seeds are bitegmic, exalbuminous and rounded with average dimensions: length of 12.36 mm, width of 9.68 mm and thickness of 8.03 mm. The "tento" seedlings have simple and alternate leaves, with tap roots and cylindrical stem, being its germination hypogeal cryptocotyledonary.Index terms: morphology, post-seminal development, germination, Fabaceae.Morfoanatomia do fruto, da semente e da plântula de Ormosia paraensis Ducke ReSuMO -Ormosia paraensis Ducke, conhecida popularmente por tento, possui sementes ornamentais amplamente usadas na confecção de biojóias, assim como, sua madeira é usada na indústria moveleira. Para a identificação florestal e tecnologia de sementes, as informações sobre a morfoanatomia de seus frutos, sementes e plântulas são escassas. Desta forma, o objetivo no presente trabalho foi descrever morfoanatomicamente o fruto, a semente e a plântula de tento. Para a descrição morfoanatômica de tento, os frutos, as sementes e as plântulas foram avaliados por meio de microscopia óptica e eletrônica de varredura. O fruto de tento é um legume nucóide, pseudo-septado, castanho a preto, deiscente, portando uma ou duas sementes, de placentação lateral, sendo o epicarpo delgado, mesocarpo lenhoso e endocarpo esponjoso, medindo cerca de 4,4; 3,9 e 2,0 cm de comprimento, largura e espessura, respectivamente. As sementes são bitegumentadas, exalbuminosas, arredondadas, com dimensões médias: comprimento de 12,36 mm, largura de 9,68 mm e espessura de 8,03 mm. As plântulas de tento apresentam folhas simples e alternas, com raiz pivotante e caule cilíndrico, sendo a germinação do tipo hipógea criptocotiledonar.Termos para indexação: morfologia, desenvolvimento pós-seminal, germinação, Fabaceae.

“…Seeds of many Brazilian tropical tree species in the genus Eugenia (Myrtaceae) show high water content at shedding and have been considered to be sensitive to desiccation. However, among Eugenia seeds, there are different desiccation sensitivity levels based on the water content, as reported by different authors Anjos and Ferraz 1999;Andrade and Ferreira 2000;Andrade et al 2003;Delgado and Barbedo 2007;Masetto et al 2008). Delgado and Barbedo (2007), for example, identified three different levels of critical water content (described as fresh mass basis) for the seeds of six species of Eugenia, from 65 (the most sensitive seeds) to 45% (the least sensitive seeds).…”
