Abstract
O objetivo deste trabalho foi avaliar a viabilidade do uso do marmeleiro 'Japonês' como porta-enxerto para cultivares de pereira com interenxertos de outras cultivares de marmeleiro em dupla enxertia. Pereiras 'Seleta' e 'Triunfo' foram enxertadas pelo processo de borbulhia e garfagem em garfos de 15 cm dos marmeleiros 'Portugal', 'Provence', 'Mendoza Inta-37' e 'Smyrna de Harcy'. Os garfos enxertados foram armazenados em câmara fria (4ºC) por 24 horas e, em seguida, foram enxertados pelo processo de garfagem tipo fenda cheia em porta-enxertos do marmeleiro 'Japonês'. O delineamento experimental foi inteiramente casualizado em arranjo fatorial 2x2x4. Após 60 e 120 dias, foram mensurados a percentagem de brotação dos enxertos e dos interenxertos, o diâmetro e o comprimento médio e a massa de matéria seca dos enxertos. Não houve interação tripla e dupla entre os fatores estudados, apenas diferença entre os fatores isolados. Houve diferença na percentagem de brotação apenas entre os métodos de enxertia e as cultivares de marmeleiro utilizadas como interenxertos. A dupla enxertia é viável na produção de mudas interenxertadas de pereira no porta-enxerto 'Japonês' com interenxerto do marmeleiro de gênero Cydonia.
The objective of this work was to evaluate the viability of using 'Japonês' quince as rootstock for pear tree cultivars through intergrafting with other quince cultivars using the double-grafting process. 'Seleta' and 'Triunfo' pear trees were grafted by budding and cleft grafting onto 15-cm clefts of 'Portugal', 'Provence', 'Mendoza Inta-37' and 'Smyrna de Harcy' quince trees. The grafted clafts were stored in a cold chamber (4ºC) for 24 hours, and were then grafted onto 'Japonês' roostocks by full-rift cleft grafting. A completely randomized design with 2x2x4 factorial arrangement was used. After 60 and 120 days, the percentage of sprouting, diameter, the medium length and the dry mass of the grafts and intergrafts were evaluated. No double or triple interaction between the studied factors was detected, only differences among isolated factors. Differences in sprouting percentage were detected only between the grafting methods and the quince cultivars used as intergrafts. Double-grafting is viable for pear seedling production using 'Japonês' rootstocks intergrafted with Cydonia quince trees.
