dc.description.abstractCalophyllum brasiliense Cambess. is a tree species that is presented as an alternative to replace endangered species of hardwood. The morphology and anatomy of the seedling of this species is the object of the present study. Seedlings at different stages of development were obtained in greenhouse and analyzed fresh and fixed in FAA (Formalin-Acetic-Alcohol) 50. The anatomical analysis was done by the freehand and microtome sections, according to standard techniques in plant anatomy. The seedling and/or tirodendro is cryptocotylar and hypogeal, has cataphylls, and presents eophylls and metaphylls simple with venation pinnate craspedodromous simple. The root is polyarch, the hypocotyl is very short, the cotyledons have an oily and starchy reserve, the epicotyl has stem structure, and eophylls and metaphylls are dorsiventral. The seedling may be classified in the Horsfieldia type/subtype.en
dc.description.abstractCalophyllum brasiliense Cambess. é uma planta arbórea que se apresenta como possível alternativa para substituir espécies em extinção com madeira nobre. A morfologia e anatomia da plântula desta espécie é objeto do presente trabalho. As plântulas, em diferentes fases de desenvolvimento, foram obtidas em casa de vegetação e analisadas a fresco e fixadas em FAA 50. A análise anatômica foi feita mediante seções a mão livre e microtômicas, de acordo com técnicas usuais em anatomia vegetal. A plântula e/ou tirodendro é criptocotiledonar e hipogeia, possui catafilos, e apresenta eófilos e metafilos simples de venação pinada craspedódroma simples. A raiz é poliarca, o hipocótilo é muito reduzido, os cotilédones possuem reserva amilácea e oleaginosa, o epicótilo tem natureza caulinar e os eofilos e metafilos são dorsiventrais. A plântula enquadra-se no tipo e subtipo Horsfieldia.pt-BR
