Propagation of GF677 Peach Rootstock by Stem Cuttings

Abstract

The rooting ability of GF677 peach rootstock by hardwood (H), semihardwood (SH), and softwood (S) stem cuttings collected January, February, May, and November, treated with various IBA concentrations—0, 500, 1000, 2000, and 3000 ppm—was studied. H cuttings collected in January and treated with 2000 ppm IBA caused significant increase in rooting (62%–5%). In addition, the SH cuttings prepared February and treated with 1000 or 2000 ppm IBA gave 42.5%. The May experiment resulted in low rooting percentage where H cuttings treated with 500 ppm IBA gave 10% rooting. In October, SH cuttings with 1000 or 3000 ppm IBA gave the highest rooting percentage (60%), while in November 90% rooting was obtained in H cuttings treated with 3000 ppm. Regardless of type of cutting, IBA at 1000, 2000, or 3000 ppm was better for rooting the GF677 than at 500 ppm. However, irrespective of IBA concentration, H and SH cuttings gave significantly high rooting percentages. On the other hand, best rooting was obtained when the stem cuttings of GF677 (regardless of wood type) were collected in November. Wounding base of the cutting of GF677 improved rooting ability.
