“…The data can be used in the species identification, a parameter which was also used by Silva et al (2014). The type of fruit is a diagnostic feature of the Leguminosae, according to Barroso et al (1999), Lopes et al (2012), Ojeda et al (2013), Albuquerque et al (2015), and the classic studies in morphology. Barroso et al (1999) classified the genus Apuleia as samaroid-type legume, dry undeiscent, flat and compressed, adapted to anemochorous seed dispersal with one to a few seeds, oblique, slightly coriaceous, with sparing-spongy mesocarp.…”

-Apuleia molaris spruce ex benth, commonly known in Brazil as "amarelão," is a fast-growing forest plant with a potential for use in reforestation; however, there is little information about the physiology and morphology of its fruits, seeds, and seedlings. Thus, the objective of this work was to describe the morphology of the fruits, seeds, and seedlings, in addition to the anatomic patterns of seedlings, as a contribution to the technical-scientific knowledge and production of amazonian species for reforestation in the state of Pará. For this purpose, the morphological descriptions followed the parameters from specialized literature and the common techniques used in plant anatomy. The species presents leguminous fruit; seeds with pleurogram, average dimensions of 51.21, 21.33, and 2.09 mm length, width, and thickness, respectively; and seedlings with eophyll and pinnate metaphylls, cordiform, phanerocotylar germination, epigaeous, and foliaceous. Eophylls and metaphylls present uniseriate epidermis, collateral and dorsiventral vascular bundle. The morphological characteristics may help in field identification and in the identification of young plants, aiding the production of seedlings of this species. Furthermore, anatomically, the hypocotyl has no striking differences from the root.Index terms: taxonomic identification, seedling production, seed technology.Aspectos morfológicos de frutos, sementes e morfo-anatômico de plântulas de apuleia molaris spruce ex benth.RESUMO -O amarelão (Apuleia molaris Spruce ex Benth.) é uma essência florestal de rápido crescimento, com potencial para o reflorestamento, entretanto existem poucas informações a respeito da tecnologia e morfologia dos frutos, sementes e plântulas. Com isso, o objetivo do presente trabalho foi descrever a morfologia de frutos, sementes e plântulas, além dos padrões anatômicos das plântulas, como contribuição para o conhecimento técnico-científico e produção de espécies amazônicas para o reflorestamento no Estado do Pará. Para isso, as descrições morfológicas seguiram os parâmetros de literatura especializada e as informações anatômicas técnicas usuais em anatomia vegetal. A espécie apresenta frutos do tipo legume, semente com pleurograma, as sementes possuem dimensões médias de 51,21; 21,33; 2,09 mm para comprimento, largura e espessura respectivamente, e as plântulas com eofilos e metafilos imparipenados, cordiforme, germinação fânero cotiledonar, epigea, foliácea. Os eofilos e metafilos apresentam epiderme unisseriada, feixe vascular colateral e dorsiventral. As características morfológicas podem auxiliar na identificação em campo, e na identificação de plantas jovens, auxiliando a produção de mudas da referida espécie, anatomicamente o hipocótilo não apresenta diferenças marcantes da raiz.Termos para indexação: identificação taxonômica, produção de mudas, tecnologia de sementes.

“…As for the seed embryo of Parkia gigantocarpa Ducke, it is linear-axial, with cotyledons crass, straight, convex, and dominant, and at the base, there is a groove where the insertion point of the cotyledons in the embryonic axis is located (RIBEIRO et al, 2015). In seeds of Bowdichia virgilioides Kunth, the embryo is invaginated, filling the entire seed, being considered total in size, of green coloration, ellipsoid format, cotyledons with storage, and a clear delineation between the hypocotyl-radicle axis and imperceptible plume (ALBUQUERQUE et al, 2015).…”

“…In the study of seed germination in Clitoria fairchildiana R.A.Howard, Costa et al (2014) did not observe the occurrence of phase III of imbibition and attributed this to the deterioration of the seeds. On the other hand, Albuquerque et al (2015) identified the three phases of the imbibition in the seeds of Bowdichia virgilioides Kunth and observed the occurrence of phase III when the seeds returned to absorb water, which culminated with the root protrusion after 48 h of imbibition.…”

For the seeds of Bowdichia virgilioides Kunth, Albuquerque et al (2015) found epigeal, phanerocotiledonar germination. Similarly, Ferreira and Barreto (2015) classified the germination of the seeds of Caesalpinia echinata Lam.…”

Dimorphandra gardneriana Tul. is a legume, the fruits of which are used in routine extraction by the pharmaceutical industry. The objective was to study the morphological aspects of seeds, germination, seedlings, and young plants of Dimorphandra gardneriana Tul. The study was conducted at the Laboratory of Seed Analysis (LAS), Center of Agricultural Sciences, Federal University of Paraíba (CCA-UFPB), Areia - PB. The external morphological characteristics observed of the seeds were color, texture, and consistency of the teguments; seed shape; hilum and micropyle position; color and thickness of raphe and other structures present; besides internal embryo characteristics (cotyledons, hypocotyl-radicle axis, plumule, and central cylinder); and presence of the endosperm. The seed imbibition curve was determined by the weight of the seeds over a period of 90 h, evaluated every 6 h, with germination being considered as the protrusion of the primary root, or the moment when the primary root breaks the integument, and normal seedlings were evaluated on the 5th day after sowing. Most of the morphological characteristics identified in the plants and seedlings of D. gardneriana resembled those observed for other species of the same genus. The seeds of D. gardneriana Tul., were medium sized, with an average length of 11.95 mm, width of 5.33 mm, and thickness of 4.3 mm, unitegmic with a hard tegument, and impermeable to water. The process of imbibition of the seeds was initially slow and the three-phase curve of imbibition was not clear. The germination was epigeic and phanerocotiledonar and began on the 5th day after sowing.

“…Bowdichia virgilioides, known as sucupira, is thus the focus of this study. It is an arboreal species belonging to the Fabaceae family (Albuquerque et al, 2015, Cardoso, 2017 used in forest restoration due to its fast growth and low soil fertility requirement (Lorenzi, 2009). There are no reports in the literature on the influence of the collection environment on the quality of seeds of this species.…”

Considering the growing demand for seed production and seedlings for forest restoration, addressing the implications of landscape changes regarding germination of native species becomes of great value for directing seed collections. The objective of this study is to evaluate the influence of seed collection environment on germination and biometry of fruits and diaspores of Bowdichia virgilioides. Fruits were collected in two forest fragments with distinct characteristics (forest I, open canopy; and forest II, closed canopy), and in isolated trees in pastures. Fruit and seed biometry of the three collection environments was carried out, and a germination test was conducted in a completely randomized design with three treatments (forest I, forest II, and open area) and twenty replicates. Collection site, and therefore changes in forest cover, influences the biometry of fruits and seeds, resulting in lighter seeds and fruits with a smaller size in the fragment with a recent history of disturbance (forest I), as well as the vigor of diaspores of Bowdichia virgilioides. Seeds from forest I expressed a greater vigor, while seeds from the pasture area presented a higher propensity to death and formation of abnormal seedlings. For the production of seedlings and commercialization of seeds for forest restoration, the environment of origin of seeds should be taken into account. It is not recommended to use lots of seedlings from Bowdichia virgilioides seeds from isolated trees, such as those located on pastures and roads.
