Ecofisiologia da germina？？o de sementes de Campomanesia pubescens

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°c alternate, 25 and 30°c 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°c 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°c, enables a better expression of the force. the seeds of bush gabiroba are intolerant to desiccation and can be classified as recalcitrant.
