Morphological characterization of fruits, seeds and germination of Allophylus edulis (St.- Hil.) Radlk. (Sapindaceae). Rev. bras. sementes [online]. 2005, vol.27, n.2, pp. 59-66.

The aim of this research was to characterize morphologically internal and external structures of fruits and seeds and to describe and illustrate the external seedling morphology of Allophylus edulis (St.- Hil.) Radk. from seed germination. In order to describe fruits, internal and external details related to texture, consistency, color, pilosity, brightness, shape, number of seeds per fruit and shedding were observed. Some external aspects of seeds were analyzed, including size, color, texture, consistency, shape, hilum and micropyle position. Regarding the internal characteristics the endosperm presence or absence and cotyledon, embryo axes and plumule type, shape and color. Germination was considered from radicle protrusion to the protophilus emission and seedlings were considered stable when all the protophilus were expanded. The fruits of Allophylus edulis are of the type coca, globose, indehiscent and monospermic. The seeds are ovoid, without endosperm and the embryo occupies the whole seed, more or less bent and slightly tablet. The germination of the seeds has beginning to the eighth day and it can be contained in the fifteenth day, after to planting.
