Abstract
The quince tree has always been commercially propagated by cuttings.
Due to low vigor of the young plants, mainly in the first years of the orchard, a series of works was developed in Brazil in order to make it possible to use the Japonês quince (Chaenomeles japonica Koehne) as a rootstock.
The results were satisfactory but the lack of other options of other highly vigorous rootstocks for quince tree and due to the observations in nursery and field of the high vigor of the pear rootstocks Taiwan Nashi-C (Pyrus calleryana Decne.), this work was developed to verify the performance of quince cultivars grafted on these rootstocks by bud grafting.
The Japonês, Mendoza Inta-37, Portugal, Smyrna and Provence quinces were grafted by the cleft grafting method onto Taiwan Nashi-C and Japonês seedlings and maintained in plastic bags (3 L of capacity of substrate) in January.
The scion sticks used had three buds each and were collected from the mother plants at the Agronomic Institute (IAC). The young plants were maintained in the nursery and evaluated after 60 days for the percentage of sprouted grafts.
The length and diameter of the grafts were measured 90 and 150 days after grafting.
Although the sprout percentage has reached the maximum of 25%, there was no statistical difference between the two rootstocks; however, for the stocks that had sprouted, there was an excellent development in the sprouting, mainly for the quince trees grafted on Taiwan Nashi-C, the exception occurred with the Japonês quince, that can only be grafted on rootstocks of the same species.
