The objective of this work was to verify the cold stratification associated with the application of IBA, in rooting of juvenile cutting of the 'Japonês' quince. Woody cutting of the 'Japonês' quince (Chaenomelis sinensis L.) were collected in seedlings with one year old and 130 cm of height, standardized with 25 cm of length, without leaves and diameter of 0.8 cm. A part of the cutting was cold stratificated for 30 days (cuttings in humidified newspaper and protected with plastic sack at 4ºC) and other part placed directly to rooting, in nursery conditions with 50% of brightness. The cuttings were treated with different concentrations of IBA (0, 1000, 2000 and 3000 mg.L-1), for 10 seconds. After 90 days, the percentage of cuttings rooted was evaluated the percentage of that one with callous and sprouted, as vellas, the mean number of sprouts, leaves and roots by cuttings. Cuttings is not cold stratification and treat with 1000 mg.L-1 of IBA.
