Morpho-anatomical study of Protium tenuifolium (Engl.) Engl plants

Protium Burm.f. stands out for its diversity of species in the Amazon. Therefore, objective present work was to describe morphological characters fruits, seeds and seedlings, as well provide information on germination P. tenuifolium (Engl.) Engl. until initial seedling growth. The fruits highlighted were collected from January April area Manoel Preto/Anani Hill complex, Sustainable Development Reserve Iratapuru river (SDR), municipality Laranjal do Jari, Amapá. These are ellipsoid with a rounded base, an average size 1.5 - 2.8 x 0.8 2.2 0.7 cm, slightly acute apex short stipule, their weight ranges 0.6 5.1 g. They can one, two or three pyrenes per fruit. pyrene is green dark green, ovoid shape, narrowing at one poles, 1.1 1.8 1.2 0.1 g bone consistency. It presents, region funicular connection, white spot which consistency texture different rest pyrene. epigeal type, cryptocotyledonar, axis between cotyledons, has permanent reserve adhered seedling. reaches stage about 30 days after sowing. axial root system; yellowish brown cylindrical primary thin, yellowish, secondary roots irregularly distributed along root. epicotyl cylindrical, erect, relation hypocotyl, ca 2 mm long, sub-woody, pubescent. next leaves composed, unifoliated, alternating they have some similar characteristics those described first leaves, except petiole size, since larger, 7 10 cm. From these characteristics, individual already considered young plant.
