%X the gabiroba bush [campomanesia pubescens (dc.) o. berg. (myrtaceae)], a native species of the cerrado is considered a plant with melliferous, ornamental and medicinal potential. aiming to evaluate the influence of abiotic factors on seed germination, two experiments were conducted. the first was conducted in a completely randomized design in a factorial design(4x3x2), composed of four temperatures (15-25, 20-30¡ãc alternate, 25 and 30¡ãc constant), 3 substrates (paper, sand and vermiculite) and two light conditions (light and dark). the second experiment aimed to evaluate the tolerance to desiccation of fresh seeds dried superficially, with 35% of water, by drying it in oven with forced ventilation of air at 30¡ãc for 30, 60, 90, 120, 150, 180, 260, 360, 750 and 810 minutes. to evaluate the physiological quality of seeds gabiroba, shrub planting on paper, in the dark and 30¡ãc, enables a better expression of the force. the seeds of bush gabiroba are intolerant to desiccation and can be classified as recalcitrant.
