The search to exotic fruits by the consumers and producers have in creasing in the latest years. The commercialization in CEAGESP is being similar to the flowers, that are an important part. The dovialis can be used in this way and the present research was conduced due the ausence of technical information about this culture. Evaluate the influence of the temperature on percentage of germination of seeds of this plant. The experiment was conduced in the Laboratory of Seeds, located in the Department of Vegetable Production, of FCAV - UNESP - Campus of Jaboticabal/SP, using seeds that were extracted from ripe fruits of dovialis trees, washed, placed to dry on shade and so conditioned in gerbox, being realized 4 replications with 10 seeds in each one and the treatments were composed by 4 temperatures: 15, 20, 25 and 35ºC, in a experimental delineation entirely randomized. The values of percentage of germination were transformed in arc sen x/ 100 . The averages were compared by the test of Tukey, with 5% of probability. Were realized daily evaluations of the number of germinated seeds, being the percentage of germination represented by the adding of the obtained plants, and the VIG was calculated according to Maguire (1962). Through the obtained results in this research, can be concluded that the temperatures of 20 and 25ºC were the most appropriated to a higher and faster germination for the specie in study.
