[Morphology and anatomy of the fruit and seed in development of Guarea macrophylla Vahl. (Meltaceae)].

Abstract

Morphology and anatomy of the fruit and seed in development of Guarea macrophylla Vahl. were studied in flowers and fruits collected in secondary forests of Maringá, Paraná, Brazil. Pericarp originates from the wall of the ovary and is constituted of epidermic exocarp, parenchymatous mesocarp with brachysclereids and fibrous and lignified endocarp. The seed develops from the hemianatropous, bitegmic and crassinucellate ovule and it is classified as an exotegmic and exalbuminous one. Exotesta and mesotesta constitute the red sarcotesta, with oily content.
