MORPHOLOGY OF THE FRUIT, SEEDS AND SEEDLINGS OF Eschweilera ovata (Cambess.) Miers

Abstract

O estudo morfol\uf3gico de sementes e pl\ue2ntulas, com o objetivo de obter um maior conhecimento de suas estruturas, al\ue9m de fornecer informa\ue7\uf5es sobre a germina\ue7\ue3o, viabilidade, armazenamento e m\ue9todos de semeadura, auxilia a an\ue1lise do ciclo vegetativo das esp\ue9cies, fornecendo informa\ue7\uf5es relativas \ue0 identifica\ue7\ue3o. O principal objetivo deste trabalho foi desenvolver metodologia de identifica\ue7\ue3o morfol\uf3gica de frutos, sementes e pl\ue2ntulas de imbiriba ( Eschweilera ovata (Cambess.) Miers), por meio de descri\ue7\uf5es e ilustra\ue7\uf5es das caracter\uedsticas morfol\uf3gicas externas e internas. Os frutos e as sementes foram colhidos no Parque Estadual de Dois Irm\ue3os, no munic\uedpio de Recife-PE e conduzidos em sacos de polietileno para o Laborat\uf3rio de Sementes do Departamento de Agronomia da Universidade Federal Rural de Pernambuco. Foi realizada caracteriza\ue7\ue3o morfol\uf3gica dos frutos, sementes e pl\ue2ntulas, sendo tomadas as medidas de comprimento e largura. A descri\ue7\ue3o foi feita com aux\uedlio do microsc\uf3pio estereosc\uf3pico binocular. As sementes foram desinfestadas com solu\ue7\ue3o de hipoclorito de s\uf3dio a 5% durante cinco minutos e semeadas em substrato sobre vermiculita, esterilizado e umedecido com solu\ue7\ue3o de nistatina a 0,2%. Constatou-se que os frutos constituem-se em um pix\ueddio, fruto seco, em forma de sino. As sementes de imbiriba apresentam arilo funicular lateral e endosperma abundante, possuem germina\ue7\ue3o hip\uf3gea, sendo a pl\ue2ntula classificada como criptocotiledonar, ocorrendo poliembrionia em torno de 4%.The study of seeds and seedlings morphology the purpose to obtain a larger knowledge their structures, besides supplying information about the germination, viability, storage and sowing methods, it aid the analysis of the vegetative cycle of the species supplying relative information to the identification. The main objective of this work was to develop methodology of identification of fruits, seeds and seedlings of ( Eschweilera ovata (Cambess.) Miers) through descriptions and illustrations of the external and internal morphological characteristics. The fruits and the seeds were harvested in the State Park of Dois Irm\ue3os, in the municipal district of Recife-PE, Brasil, and led in sacks of polyethylene to the Laboratory of Seeds of the Department of Agronomy of the Rural Federal University of Pernambuco. The morphological characterization of the fruits, seeds and seedlings were accomplished, being taken measures of length and width. The description was made with aid of the estereoscopic binocular microscope. The seeds were desinfected with solution of sodium hypochlorite to 5% for five minutes and sowed into vermiculite sterilized and moisture with nistatine solution to 0,2%. It was found that the fruits are in a pix\ueddio, dried fruit, bell-shaped. The seeds have imbiriba aryl funicular side and abundant endosperm, has hypogeal germination, the seedlings being classified as cryptocotyledonary, polyembryony occurring around 4%
