SCHMITZ, Juliano Dutra et al. Performance of peach rootstocks in different crop systems for the production of 'Chimarrita' seedlings. Rev. Ceres [online]. 2014, vol.61, n.2, pp.293-297. ISSN 0034-737X.

The aim of this study was to evaluate the performance of 'Okinawa' and 'Capdeboscq' peach rootstocks in three crop systems for the production of 'Chimarrita' seedlings. The assay was installed in commercial nursery at Pelotas. The evaluation period was from seeding, in 12 July 2010, until the next year, 365 days after seeding, in July 2011. The treatments consisted of two rootstocks: 'Okinawa' and 'Capdeboscq'; and three crop systems: exclusively in the field, on the benches outside the greenhouse, on benches inside the greenhouse and with plastic covering. The experiment was arranged in a in a 2 x 3 factorial (two rootstocks and three crop systems, respectively) randomized block design. In this study, it was possible to produce seedlings of 'Chimarrita' with similar vigor using the rootstocks 'Okinawa' and 'Capdeboscq'. Besides, the system in field provide more vigorous scions regardless of the rootstock used.
