Resumo: The papaya (Carica papaya L.) propagation is made by seedlings produced from true seeds. Although the use of seeds in the implementation of commercial papaya orchards is well documented in literature, studies on the anatomy and morphology of these structures are in small number. In present work morphological and anatomical aspects of the seeds from two papaya genotypes Sunrise Solo 783 and Formosa Roxo 45,belonging to two grand groups ´Solo` and ´Formosa` are described. These genotypes were obtained of Gemoplasm Bank of the Universidade Estadual do Norte Fluminense Darcy Ribeiro (UENF) in cooperation with the company Caliman Agricola S.A. The work was carried out at the Eletronic Microscopy and Ultra-strutural Analisys Laboratory of the Universidade Federal de Lavras (UFLA). To make the morphological characterization, the seeds were dissected carefully by hand and observed in the stereomicroscope. For the anatomic studies, seeds were prepared according to the routine protocol of the LME and observed in scanning electronic microscope Leo Evo 40, at work distance of 10 mm under high vacuum conditions. Measurements were made using the Software Leo User Interface (Version Leo 3.2). The results of the morphological studies provide adequate conditions to observe the different structures of the papaya seeds and from anatomic studies it was possible to verify structural and dimensional differences among the cells of the two genotypes under investigation.
