Resumo: 	The grapevine propagation is usually made using grafting directly in the field, on rootstocks planted the previous year in situ, or rooted in the nursery. In this process the change takes about two years to be formed. Given the above, the aim of the present work in advance to obtain  grapevine plants in grafting times and root induction through basal heating. As rootstock used the grapevine hybrid ‘Riparia’ x ‘Rupestris 101-14’ and the cv. ‘Niagara Branca’. The experimental design was a randomized complete block, in a 3x5 factorial scheme, containing four replications, and resulted from two factors, with factor A, consisting of three pre-treatments for rootstock cuttings (control = A1, humid = 24 hours in water = A2 and 2000 mg L-1 of AIB in hydroalcoholic solution 50% = A3) x five combinations (B) between root induction, grafting and planting time, being: B1 = table grafting followed by root induction by heating basal at 21ºC for 30 days and planting in plastic bags; B2 = root induction of rootstocks by basal heating at 21ºC for 30 days, grafting 30 days after collection and planting in plastic bags. B3 = root induction of rootstocks by basal heating at 21ºC for 30 days, planting in plastic bags and grafting 60 days after collection; B4 = table grafting and planting in plastic bags and B5 = planting in plastic bags and grafting 60 days after collection. The basal heating chamber induced a high rooting rate of cuttings (80%), but did not affect the rate of plants formation. Pretreatment with AIB was unfavorable to the formation of seedlings. It is possible to obtain grape seedlings at 7 months. Treatment with basal heating resulted in high rooting rate of cuttings (80%), but did not affect the percentage of seedling.
