This work was carried out at the Department of Plant Production/Horticulture of the Faculdade de Ciências Agronômicas (FCA) of the Universidade Estadual Paulista (UNESP) located in Botucatu (SP, Brazil). The purpose of this study was to evaluate the influence of substrate and pot type on rooting of stem hardwood cuttings of peach cultivar Okinawa with different diameters. The cuttings were treated with 2.5g L-1 of IBA. The cuttings were maintained in greenhouse for 50 days. The treatments consisted of the combination of six substrate compositions: sand, carbonized rice husk, vermiculite, sand + carbonized rice husk, sand + vermiculite, and carbonized rice husk + vermiculite, mixture at proportion 1:1v/v and three types of pots: plastic bags, polystyrene trays, plastic trays and two groups of cutting diameter: 2 to 6mm and 6 to 10mm. The highest rooting frequency was obtained with plastic bag, and vermiculite independent of cutting diameter.
