This research had the objective of isolate, identifying and select isolates (s) of Fusarium spp. in cucumber seeds and checking the influence of this (these) isolate(s) on the physiological quality. Three batches were used and treatments utilized consisted in absolute witness; PDA + mannitol - 0.8Mpa; PDA pure; PDA + mannitol - 0.8Mpa + fungi; and PDA + fungi. The physiological quality was assessed by tests carried out in laboratory and greenhouse. Five isolates off Fusarium verticillioides were isolated and it was not possible to affirm its transmission through seed. The hydric restriction technique was efficient to provide the infection of cucumber seeds, since this fungus affected the physiological quality of cucumber seeds of this cultivar.
