INTERSPECIFIC AND INTERGENERIC PEAR, APPLE AND QUINCE GRAFTING USING PYRUS CALLERYANA AS ROOTSTOCK

Due to the lack of rootstock options for pear and quince trees in Brazil, and the difficulties with apple nursery tree production, this work was carried out to verify the take and development of pear cultivars grafted on ‘Taiwan Mamenashi’ rootstock and apple and quince trees grafted on ‘Taiwan Nashi-C’ rootstock (Pyrus calleryana Decne.). Buds of ‘Tenra’, ‘Centenária’, ‘Triunfo’, ‘Seleta’ and ‘Primorosa’ pear trees, ‘Condessa’, ‘Galícia’, ‘Princesa’, ‘Eva’ and ‘Rainha’ apple trees and ‘Mendoza Inta-37’, ‘Smyrna’, ‘Japonês’, ‘Provence’ and ‘Portugal’ quince trees, were in the summer, grafted onto the referred pear rootstocks, which were eight months old and 0.8 cm of diameter.
Thirty days after grafting, the rootstocks were pruned off right above the graft area.
There was more than 90% success of bud sprouting for the pear tree cultivars and more than 72.5% for the apple cultivars; for quince trees, the ‘Smyrna’ had 20% of sprouting and the others 10–15%, except for ‘Japonês’, that didn’t sprout at all.
After 90 and 150 days from the time of grafting, the length and average diameter of the sprouts were evaluated.
In the last evaluation, the sprouting of pear cultivars were between 34 to 39 cm in length, should be with larger shoot diameters for ‘Primorosa’ and ‘Tenra’; the apple cultivars produced sprouting with lengths from 42.9 to 49.1 cm; and the sprouting of ‘Smyrna’ and ‘Portugal’ quinces were 82.6 and 81.2 cm, respectively.
