PIO, Rafael et al. Development of 31 cultivars of quince grafted in the japanese rootstock. Rev. Bras. Frutic. [online]. 2008, vol.30, n.2, pp. 466-470. ISSN 1806-9967. http://dx.doi.org/10.1590/S0100-29452008000200034.
The quinces have always been commercially propagated by means of rooting stem cuttings. Due to the lack vigor of the seedlings, especilly afer the first years whih followed the planting season, a sequency of studies were developed in Brazil aiming to permit the use of 'Japanese' quinces (Chaenomeles sinensis Koehne) as a rootstock for the quinces. Beacuse of lack of information, this experiment was developed with the aim of verifying the development of different rootstock cultivars. The 'Japanese' quinces, 'MC', 'Adams', 'Van Deman', 'Provence', 'Cheldow', 'Smyrna', 'Rea's Mamouth', 'De Patras', 'De Vranja', 'Lajeado', 'Champion', 'Mendoza Inta-37', 'Alongado', 'Meech Prolific', 'Bereckzy', 'Alaranjado', 'Kiakami', 'Du Lot', 'Radaelli', 'CTS 207', 'D'Angers', 'Zuquerinetta', 'BA 29', 'Constantinopla', 'Marmelo Pêra', 'Apple', 'Portugal', 'Füller', 'Meliforme' and 'Pineapple' were grafted by means of clevis process in 'Japanese' seedlings, by the full slit method. Clevis with three gems were used, collected from parent plants. The seedlings were kept in greenhouse, and the percentage of sprout clevis was evaluated after 60 days. The length and medium diameter of the graft were evaluated in the 60; 90; 120 e 150 days after the grafting. It was concluded that the quinces presented good affinity. with the 'Japanese' rootstock. The cultivars 'Van Deman', 'Japonês', 'Smyrna', 'De Vranja', 'Lajeado', 'Mendoza Inta-37', 'Alongado', 'Meech Prolific', 'Meliforme', 'Cheldow', 'Champion', 'Bereckzy' and 'De Patras'were the ones that had the highest vigor in the greenhouse phase.
