Morfologia de frutos, sementes e plântulas de Magonia pubescens a. St. Hil. (Sapindaceae)

Abstract

Magonia pubescens, known as tinguí, from the Sapindaceae family, is a characteristic species of the Brazilian cerrado, is resistant to poor soils, is indicated for plantations in degraded areas and of long permanence. The recognition of morphological characters of fruits and seeds, as well as the first sets of plants, is a tool for identification of species. The present work had the objective of analyzing, describing and illustrating the morphological characteristics of fruits, seeds and seedlings of the species. The characteristics of the fruits is was found: type, color, size, texture and number of healthy seeds per fruit, while seeds: color, dimensions, texture and consistency of the teguments, shape, hilo (external characteristics), embryo type, presence or absence of endosperm (internal characteristics) As for the seedling it was detailed: radicle, primary root, secondary root, coleto, hypocotyl, cotyledons, epicotyl and eophiles. The fruit is loculicide capsule, indecent, powdery rough texture, medium outlet 5.98 cm, with an average amount of 15 seeds and dark brown pericarp. The seed is winged, transverse oblong, smooth, wavy texture, coloration from light brown to reddish, forehead of cartácea aspect and brittle appearance wing enfolding all seed average length 3.69 cm and mean thickness 0.35 cm The germination was of the hipógea fanerocotiledonar type, began on the fourth day after sowing and on the twenty-two day the complete seedling formation was given.
