The quince belongs from the family Rosaceae. Now, it has been used as rootstock tree door-graft because it induce dwarf plants. The floroglucinol is a phenolic compost, which effects is by increased the auxine and that tends to induce and to increase hardwoody cuttings. The present work was carried out in a greenhouse with intermittent mist writh the objective to determine the best quince cultivars in relation to its capacity of rooting hardwoody cuttings, and the best floroglucinol concentration for the root induction. The cultivars Pineapple, Meliform, Prolonged, Radaelli, Portugal, Inta and MC were used. They were submitted to three treatments of different floroglucinol concentrations (zero, 1500 and 3000 mg.L-1). The cuttings with 12 cm and ½ leaf in the superior part were conditioned in plastic boxes contends medium vermiculita. The experimental design used random blocks in the factorial arrangement (3 x 7), with 3 repetition and 5 cuttings for replication (15 cuttings for treatments). The analyzed variables were determination of the percentage of rooting, number of roots and percentage of cuttings shottings. It was observed that, independently of the tested concentration, the floroglucinol, did not induce the rooting of hardwoody cuttings of the cultivars tested. Cultivar MC presented better percentage of rooting, number of roots and percentage of shottings.
