“…-Sapotaceae) ... para o reconhecimento de essências florestais no estágio juvenil nos estudos de sucessão e regeneração natural em formações florestais, sendo na verdade o ponto de partida (BELTRATI, 1984;GALDINO;FERRAZ, 2007;GARWOOD, 1996;GURGEL et al, 2006;OLIVEIRA, 1993;PINHEIRO et al, 1989;RODERJAN, 1983). Os estudos sobre autoecologia de espécies envolvendo a morfologia de propágulos e desenvolvimento inicial de plântulas, também têm aplicações práticas em estudos ecológicos, no manejo florestal e na conservação da fauna (OLIVEIRA, 1993 (FERREIRA et al, 2001;OLIVEIRA, 1993;HIRT;FLORES, 2012). Muitas vezes, a longa duração do período de germinação e/ou o lento desenvolvimento inicial das plântulas, são comportamentos peculiares das espécies, e portanto, não são considerados no planejamento e no seu processo de produção (LEONHARDT et al, 2008).…”

Morphological aspects of fruits, seeds, and seedlings, and anatomy of seedlings of apuleia molaris spruce ex benth

et al. 2016

-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.

Morphology of fruits, seeds, seedlings and saplings of three species of Macrolobium Schreb. (Leguminosae, Caesalpinioideae) in the Brazilian Amazon floodplain

et al. 2014

The evaluation of the post-germination phases of plants allows the recognition of transitional structures that support the relationships among taxa and their establishment. Together with fruit and seeds, seedlings and saplings provide useful characters for identifying many species. This study aimed to describe and characterize the morphology of the fruits, seeds, seedlings and saplings of Macrolobium acaciifolium, M. bifolium and M. pendulum, as well as to evaluate the ecological, taxonomic and phylogenetic value of the structures identified. In this work, the seeds were sown in plastic trays with sterilized sand and sawdust, without pre-germination treatment. The fruits of the three species are woody legumes, dehiscent fruit or indehiscent fruit. The seeds have seed coats with or without venation and variable embryos, with plumules differing among the three species; this trait can be helpful in distinguishing among the species studied. The seedlings are of the cryptocotylar-hypogeal-reserve or phanerocotylar-epigeal-reserve type. Macrolobium bifolium and M. pendulum are similar species, differing in only a few characters. These characters have taxonomic value and aid species identification. The characteristics of M. pendulum are described here for the first time.
