The effects of growth regulator concentrations were evaluated for sweet passion fruit (Passiflora alata, Dryander) seedling emergence and growth. The seeds were treated with gibberellin (GA3 0, 100, 200, 300 e 400 mg/l) during 24 hours. The results obtained showed that there were not significance between the treatments, being the highest emergence percentage (97,50%) with GA3 300 mg/l at 28 days. When the seedlings were about 2-3 cm high they were sprayed with the same treatments, at 15 days intervals between the sprayings. The plants height, leaves number, dry weights of leaves plus stems and roots were evaluated. The parameters' analysis showed that GA3 300 mg/l was the best treatment to enhance the growth of sweet passion fruit seedlings.
