The tip pruning stimulates the emission of lateral shoots, thus can produce higher number of flowers, fruits and seeds. This work aimed to evaluate the effect of apex pruning on fruit and seed production in pumpkin. The treatments consisted of plants without pruning, with pruning in the sixth, eighth and tenth node of main stem. The experimental design was a randomized block, with six replications. It was studied a line of pumpkin of the Germplasm Bank of the Universidade Estadual Paulista/Faculdade de Ciências Agronômicas. The characteristics evaluated were: number of branches per plant and fruit position in branches of the plant production (number and weight) of fruits per plant, fruit yield, fruit average weight, fruit length and diameter, seed weight per fruit, seed yield and quality (germination test, first count, thousand seed weight, emergence, speed of emergence and accelerated aging). There was a significant difference only for number of secondary branches per plant and thousand seed weight, with larger values for plants that have not been pruned. It was obtained high average of germination (94%) and good fruit (16.9 t ha-1) and seed (148 kg ha-1) yield. The apex pruning does not influence the production of fruits and seeds, as well as the physiological seed quality in pumpkin.
